Out with the old, in with the new.


This week I had the opportunity to work with CERTUS on a engine change. He put the new ROTAX 912 in his car and drove it down from Wisconsin to central Florida. I was busy on Tuesday so he began the disassembly by himself. When I arrived early Wednesday morning the old engine sat in a tray on the hangar floor and the shiny new engine sat proudly in her mount on the SportCruiser. Wow! 

The next few days were spent assembly and reattaching systems. Oil lines, fuel lines, cooling lines, electrical lines all have to installed and routed in a particular way. As you might expect, not all parts fit perfectly the first time. He seldom had to disassemble a previous item to install the new part. I was the "GoFor" and helped by finding wrenches, pliers, screwdrivers and such. I also leaned how to buck rivets. As each hour went by the engine turned into a system. Friday afternoon I turned the key and she came to life. All temperature and pressures in the green. No leaks, no smoke, no issues. We pushed her back into the hangar for final adjustments.

It was IFR Saturday morning but improved throughout  the day. Saturday afternoon we put the cowling back on. CERTUS and I prepared for a maintenance check flight. KLAL is a controlled field so in my initial call to ground I let them know what we would be doing. This plane doesn't have a BRS so my cockpit brief stated we would stay in the pattern. In case of engine failure he would fly the airplane and I would assist as backup and handle the radios. We would not attempt a restart and if an airport landing was not feasible we would look for something soft straight ahead. Good runup. 5050RPM on the roll. No noises, shutters or smells and the instruments were all in the green. Smooth and quiet. Two full stop landings a Go Around. She went smoothly from idle to full power without any hesitation. 

Maintenance check complete. Back to hangar, CERTUS got out and the customer got in. Same brief, same plan, and we got the same results. Acceptance check complete. Not including the transportation time, it took just 5 days to do an engine change and put the airplane back in the customer's hands.. 

Good job CERTUS.

Lake Wales X07

 Sally is healthy. I was ready for a xcountry flight. Somewhere I've never been, a runway I've never seen. A search on SkyVector led me to Lake Wales. It would be about an hour flight.

The city of Lake Wales was established near the lake in 1911–12, planned by the Lake Wales Land Company.[7] The spelling Wales was used for the city, although the lake is still generally spelled Lake Wailes. Allen Carleton Nydegger, a Civil Engineer, was contracted by the Lake Wales Land Company to plot out the community of Lake Wales. He and his crew camped on the shores of Crystal Lake and spent months plotting out the new community. In 1925 the Atlantic Coast Line Railroad built a new line from Haines City joining lines to Everglades City. A depot was opened on this line at Lake Wales. The City of Lake Wales was officially incorporated in April 1917.[8]. Wikipedia

Beautiful winter weather. Forecast was for CAVU although METARS showed some early morning fog/mist at some of the low lying airports. No interesting NOTAMS but the airport is a Skydiving center and hosts Ultralight events. 

Normal preflight and runup. This is always a good thing following some maintenance. So nice to arrive at the hangar and not find any leaks or flats. And the CHT stayed in the green for all ground operations. Nice.

Just a few students in the pattern. I guess this is the new normal for a weekday. No wait at the hold short line. 5050RPM on the takeoff roll, CHT climbed and stabilized at 238°F during the climb out. Good stuff.  Thanks CERTUS. We leveled at 2700' to stay clear of KLAL airspace and then I pushed the button to let Sally fly. Winds were about 20kts right on the nose, but it was smooth air. Headwinds aren't a problem when you're not in a hurry. I started my descent passing KBOW. 

Winds favored RW06. There were reported skydiver operations but the jump plane was just taking off as I entered on the 45. Lots of large birds in the area. I made a very nice full stop landing and got off on the first taxiway. As I taxied back one of the large birds flew over head with a rodent in its mouth. The jump plane announced skydivers in the air. I completed my checks, made my call and took off. The beautiful Bok tower was immediately in front about 2 miles away.

Bok Tower Gardens (also known as Bok Mountain Lake Sanctuary and Singing Tower) is a contemplative garden, and bird sanctuary located north of Lake Wales, Florida, United States. It consists of a 250-acre (100 ha) garden, the 205-foot (62 m) tall Singing Tower with its carillon bells, Pine Ridge Trail, Pinewood Estate, and a visitor center. The tower is built upon Iron Mountain, one of the highest points of peninsular Florida, estimated to be 295 feet (90 m) above sea level. Wikipedia

On the departure leg (not upwind leg) I saw the skydivers, about a half dozen of them.. I made my call and turned to the west to avoid them, then circled back to fly by the tower. That's definitely on our Bucket List for Florida. Time to go home.

We flew past a quiet KGIF and F57 (Jack Browns) looked like they were using one of their Cubs to go fishing. 18Kts on the tail got us home quickly. Sally performed very well for the entire flight

It's nice to have an adventure now and then.

The day CERTUS came to town


After a "project meeting" at the local Waffle House we drove over to the hangar and got organized. Tools were laid out on the table. Parts were unpacked and inspected. The cowling was removed and a close look at the engine was performed.

  1. Oil Cooler: Even with cooler weather Sally had been reporting CHT One High on several occasions. I purchased a new cooler and we removed and replaced the old one. This (of course) included an oil change.
  2. Air Filter: Some might consider this a minor change but what a difference it can make. We changed the standard to a High Flow Air K&N performance filter.
  3. Spark Plugs: About 100 hours on the old plugs. The burn looked good on all of them but it was time. Added new boots as well. Good compression checks.
  4. Ducati Rectifier: While there are better choices for E-LSAs, the Ducati is the only one I can use. I'm convinced that heat is the primary cause of failure and Florida is hot. Coupled with the CHT problem, I was getting Voltage Low alerts. Removed and replaced the old rectifier.
  5. Fuel Sump Valve: I noticed some fuel stain on the pilot side fuel sump. On close inspection I could see a "dribble". I repeatedly tried to reset the valve but failed. We removed and replaced it.
  6. Maintenance Check Flight: I knew it was better even before we got to the run up area. The CHT was rising but stabilized at about 200°F. When the oil temperature reached 122°F I powered up to 4000RPM and immediately the oil temperature dropped back down. A short wait at the hold short line was not a problem. The final test was passed during a Vy climb with no CHT alerts. 
Not a bad day's work. She's fixed.

Low Approach



Another beautiful Saturday to fly. This time
I didn't feel quite so alone. As I taxied from the hangar an executive was on final to land and as I approached the run up area a trike was landing on RWY05. (Caution Wake Turbulence!) 

We departed the pattern and headed south keeping east of I75 to stay clear of the Tampa Class B. It was a little choppy at 1000' but  Sally and I enjoyed the view. I dialed in 48x and made our initial call. The weather advisory called winds out of the east at 10G16. We were the only ones in the pattern.

Instead of passenger jets and miles of tarmac, Airport Manatee has a turf runway and an assortment of taildragger aircraft.

It's home to an eclectic mix of antique, modern and experimental aircraft, where flight instruction, fuel sales, airplane repairs and restoration, and hangar rentals are available.

Airport manager Tom Reeder calls its a grassroots, blue-collar airport. Information here

It was a fun flight.

An Autumn Flight

 A cold front moved through last night. Crisp cool air and low humidity is perfect for flying and Sally and I were long over due for some exercise. I got a late start. I haven't been sleeping well lately and after the alarm went off I lingered in bed for awhile. That gave the sun a chance to rise and allowed me to get a good weather check. It would be breezy later in the day but we definitely had "Go" conditions.

I skipped my normal breakfast and chose to stop at the local Wawa on my way to the airport. Gas was $2.05/gal, the Colombian coffee is pretty good as is the sausage/egg & cheese bagel. Very little traffic on the roads for a Saturday morning, but the normal amount of bikes, joggers and walkers were out. Biden and Trump signs were displayed along the route. I wonder how some of the neighbors get along with each other.

Now its been awhile since I visited KVDF and it occurred to me that I didn't remember the security code for the gate. I know I had a math formula to memorize it but couldn't quite remember how it went. When I pulled up to the keypad I let muscle memory do it's thing and presto, the gate opened! As I pulled up to my hangar my neighbors across the way were working on a C182. I waved but they were too busy to notice. Good social distancing I suppose. I opened my hangar and found spider webs across the doors. It had been awhile.

"Hello Sally." I good walk around revealed no issues. It's a great feeling to see good tires and no leaks. It did take a lot of pulls to get the burp. I pulled her out of the hangar, did the last few checks and buckled in. She started easily. AWOS said we should use RWY05. I was surprised by the quiet radio as we taxied over. No chatter? When I turned the corner on the taxiway the ramp looked empty. I got that "Twilight Zone" kind of feeling like I was the last guy on Earth. 

Runup was smooth. 3950rpm/3960rpm for a mag drop from 4000rpm. CHT was 220 and climbing on a cool day. That still needs attention. As I completed my checks a Cessna called on a 5 mile straight-in (finally another voice) and I replied I would get out in front of him. Sally gave me 5050rpm for takeoff and climb rate was over 1200fpm at Vy. We love the cooler air.

After 3 T&Gs we departed to the north for some avionics checks. Level at 1500' I engaged the autopilot in HDG/ALT mode. Next I put X35 in the GPS and pushed the NAV button. It was hazy with no clear horizon so I decided to use 1600'. A few minutes later we passed n Archer, opposite direction at about 1500', no factor. 

All systems checked, I put in PCM and let Sally take me there. Winds were gusting and it got a little bumpy. The wind vector showed 26 out of the northeast. Such beautiful Florida fall colors! Lush greens and...more lush greens. It's Florida! 

KPCM was reporting 8 out of the east so I set up for a T&G for RWY10. A SkyCatcher reported taxiing there as well. It was a normal approach with a slight left to right xwind and I was happy with the landing. Time to go home.

School Closed


2020 has been a difficult year and I'm forced to make a difficult decision. While the variable costs have been reduced, the fixed costs of running my flight school have gone up dramatically.  Notably, Insurance costs:
From: Aviation Insurance Resources (Orlando FL) 
Global Aerospace:  Pleasure Use:  $1801
Acceleration Aviation:  Rental & Instruction:  $5625 
I got numerous quotes from a variety of brokers but all show substantial increases over previous years.

With COVID still running strong in Florida I can't afford to take the risk of starting new students. There are certain jurisdictions that may fine the flight school for not enforcing masks. I can't afford someone launching a lawsuit stating that the flight school was negligent in their protocols and procedures.

Today I notified my students that the school will not reopen.

We had a good run.

Maybe a Solution

Video Link: CHT Diagnostics

I'm frustrated with the COVID resurgence. Tampa seems to be in full bloom and I can only hope that it will die out once this latest resurgence is over. Sally and I have been doing some maintenance so we can be ready for students if/when the pandemic subsides.

CHT 1 Hot: I rechecked all of the obvious and still found nothing amiss. Certus volunteered a used radiator (fluid cooler) to try. I removed the old, then gave the system a bath. I used a water hose on inlets and outlets and let it flush the system completely. I lightly washed the whole engine removing any grime and ran water through the used radiator for a few minutes. The shock mounts would not come off the old radiator so I ordered some new from Amazon (here). I did a taxi test and saw some improvement. With Florida temperatures reaching triple digits I called it a day.

Early the next morning I rechecked all of my previous work, added about a cup of coolant and took her for a test flight. It turned into another record breaking hot Florida day but my results still showed a major improvement over previous attempts.

Rule: No training flights if OAT exceeds 90° F.

Next: Investigate the Oil Cooler.

Note: Maybe Sally would look good with a P51 scoop.

CHT 1 High

Video: CHT 1 Test

Cylinder Head Temperature. The Rotax engine uses a fluid to cool the four cylinder heads.

I'm still struggling with this. A suggestion from Ronin5573: "The awos said 26deg cel or about 76 deg f. Not a hot day. I would have to agree that the problem is still there. Your CHT are coming up much faster then your oil.  I don't think you plane has the coolant thermostat but that would be my first guess. Considering you just changed the coolant I would suspect maybe replacing the radiator cap on the tank.  Make sure its the 1.2 bar or 17.4 psi. Also when you remove the cap look into the tank and that first  inner lip, make sure its clean.  Sometimes you will see some black residue from the seal from the cap. If you do get some light sandpaper and remove that.  Could also be a bad spring on the cap.  I have herd that if there is a small leak,  or better way of putting it is if the cap allows air to pass then it messes up the flow of the coolant and almost stops the flow. Kind of like having air in the system.  they are about 80-to 90 bucks to replace.  Just a suggestion" ~http://www.scflier.com/topic/1362-cht-high/

All good suggestions but unfortunately all tried. Perhaps its time to replace the oil cooler or water cooler?

It really gets hot in Florida. I need to find a solution.

Cleaning the Air Filter



Video: Plant City Exercise

You should be doing this for every annual/condition inspection. It's easy enough, remove the hose and one screw and it pops right out. But my hangar doesn't have easy access to water so this minor chore sometimes got missed. Mistake.


I had been noticing higher Cylinder Heat Temperatures (CHT) and as we approach the real heat of a Florida summer it became a real concern. I mentioned this to CERTUS and he recommended that I buy some K&N cleaner, take the air filter home and wash it out in my laundry tub. It takes a good day to dry before you can apply the red oil used to trap the fine particles that could get to the carburetors.

My weather was not good. Most local airports were IFR due to fog/mist. So I watched some news and drank some coffee waiting for the temperature/dew point to spread,. Democrats and Republicans still hate each other. The pandemic still has most places shut down and evidently wearing a face mask displays some kind of bias. Time to go fly.

I stopped at Wawa to get 5 gallons of premium for today's flight. The price had jumped up over 60¢/gal in a week. That wasn't talked about on the news show I just watched. Maybe I missed it. The drive to the airport was quiet as there are still not as many cars on the road.  But the airport was busy. Two schools are now flying full time and the pattern is full.

The clean filter made a difference. I had to taxi to the farthest runway and wait for a few planes to land before it was my turn. Sally had no complaints.

What a wonderful day to fly.

A Flight Over the Beach

Video:  Over the Beach

A long video about flying above the beach during the COVID19 Pandemic.

Low Approach at KVNC
Florida has just (partially) opened the beaches in the state. Some communities only allow exercising, no chairs, umbrellas, blankets, etc. Others allow sunbathing but only for a few hours. All must maintain 6' separation. I wanted to see what this looked like from the air.

(Please excuse the Pandemic haircut, the barber shops are still forbidden to open.)

How to Exercise Your Airplane

Fly it.

I planned  to do a "Twofer", by flying N905SC in the early morning then return and fly N674PS immediately after. The preflight for 5SC went well. I had cleaned the battery terminals after my last visit. The start and ground procedures went well. Light traffic in the pattern, I was surprised that one of the schools based at the airport was still flying students. However the volume had gone from 4 or 5 in the pattern to 2 or 3.

The weather was good. A scud layer at about 3000' was no factor and the visibility was fantastic. I enjoyed the view of the Tampa skyline as I exercised the avionics to insure all systems were working properly.

I flew south along the east side of I75 staying away from my "nightmare towers" as I played with the Skyview autopilot. Then went over to Plant City to see if the runway construction was completed. It wasn't. Then back home for about 0.8 hours. Plugs and covers and tie-downs completed. No gripes.

It was good to see Sally again. We had plenty of gas in the tanks. Engine burped after 30 pulls with oil 2/3 up the stick. The previous work on the right main tire looked good, the left was fine, but the nose tire was low.
"Every 20 minute job is one broken bolt away from becoming a 3 day ordeal." Anonymous
I fired up the compressor and unwound the hose to reach the nose gear. I rolled the plane back to get the valve stem aligned with the cutout on the wheel pant. But the stem was at an odd angle and I couldn't get the hose to attach. I only played with it a few minutes before deciding to take off the pant to investigate further. The tire was not low, it was flat. So my twenty minute job just turned into a 2 hour ordeal. I'm a slow but meticulous mechanic. Simple Green found some bubbles near the base of the valve stem. Fortunately I had a new tube in stock. (Thank you Certus!) It was mid afternoon by the time I was ready for a maintenance check flight. She rolled nicely out of the hangar. We did two touch (just barely letting the nose gear kiss the runway) and goes and a full stop on RWY23. I let her run the length of the runway and took the last taxiway before returning to the hangar. No shimmy, no wobble. Returned to flight flight status.

A severe cold front came through ruining any chance for flying for the next few days. When it finally cleared up we had a cool clear day to get some more exercise with Sally. Preflight was uneventful (yay!) and I decided to go up to Crystal River. It was a nice smooth flight up. Again visibility was unlimited. After I made my position report a Piper Cub replied that he was setting up for an entry to RWY36. I hadn't considered that! So I took interval on him and made my way around the pattern to a beautiful low approach about a foot off the turf. Next I turned my downwind for RWY36 into a crosswind for RWY27 to practice a crosswind landing on the asphalt. Just one T&G, it was time to go home.

I fly a VFR airplane so rarely bring up the procedures page on my 696 GPS. Also, the landing pattern a KVDF is usually so full it doesn't lend itself to practicing instrument approaches. Now that the pattern isn't so busy I decided to dial up a GPS approach just to see if I could remember how to do it. Turned out to be a lot of fun. I just may have to do this more often.

Risk Assessment.

In many states and communities, nonessential businesses have been ordered to close, taking that decision out of the hands of business owners. Aviation-related businesses, including flight schools, are included on the U.S. government’s list of essential businesses published by the Cybersecurity and Infrastructure Security Agency, which most states are following. However, it’s worth checking state and local directives, because flight schools might be listed among the nonessential enterprises that must close their doors. AOPA Link

Obviously, all the now fully understood CDC protocols should be followed: avoiding unnecessary travel, social distancing, frequent hand-cleansing etc. But since”social distancing” in a training aircraft is obviously not possible, constant cleansing, by the pilot before (and after) every flight of all surfaces with approved disinfectants is essential. Obviously, NO sharing of any personal items (especially headsets) is axiomatic. And to be honest, there is an element of trust here too. People training together have to be personally careful and absolutely truthful about previous recent travel and contacts if the group of pilots sharing airplanes and facilities is going to be safe. 

Regarding this issue, an urban setting with a more transient clientele is going to be more dangerous since the chance of exogenous COVID-19 contact from social mixing is greater. If you are a smaller club of less-mobile, regular known members in northern Idaho, you are probably going to be safer. I would highly recommend eliminating “Discovery Flights” to strangers for the same reason – potentially bringing germs into your “protected zone of known operators.” SAFE Link

Last week in this space, I suggested Covid-19 safe practices in the flight instruction environment. I wrote that in the optimistic hope that it would be sufficient. It's not. With the guidance of health professionals from both public health agencies and in private practice and with the goal of helping "flatten the curve" in mind, it's time to reassess. Some may disagree, but I believe it's time to stand down and refrain from in-cockpit flight instruction until we have broken the back of this pandemic. I say this because I cannot imagine a way of practicing any form of social distancing within the confines of an aircraft cockpit. Bob Meder, NAFI Board Chair

“Here’s the bottom line,” Merrill said. “Everyone should make every possible attempt to stay home unless you’re an essential business. And if you just can’t, you still have to maintain a 6-foot distance. And if you can’t, then you have no business being in that place because you’re putting yourself and everyone else at risk.”

The rules will apply to residents of Tampa, Temple Terrace, Plant City and unincorporated Hillsborough County. If approved Thursday, the rules go into effect at 10 p.m. Friday. Tampa Times Link

So, how to assess this? Some pundits on Facebook have determined that a Flight School is an essential business. Why, because it is a part of the national transportation industry. Not buying it. (While I hesitate to state this, I suspect the pilot shortage just got solved for the next year or so.)

Flight schools work on a razor thin budget. Already this year I've seen a 20% increase in insurance. ADS-B is an expensive mandatory maintenance upgrade for 2020. Hangar fees continue to climb, airplane fixed costs don't go away. A month without revenue could kill my business.

I've heard that two flying clubs at the same airport have taken different actions for this issue. One has closed the other stayed open. I bet the repercussions will ripple through their board meetings for years.

What to do?

My March 12th email to all students.

The coronavirus has the highest impact on elderly people. In case you haven't noticed, that would be me. Please do not come to the airport if you're sick. (Use IMSAFE). If you have just traveled to an infected part of the country, please cancel the flight even though you may feel fine. We can always reschedule. 

My March 17th email to all students.


I must use an abundance of caution and stop training flights until the coronavirus threats are over. I hope to start up again on April 1st. Stay safe. 

April 1st, 2020: an update.

My school is closed indefinitely.

However I do intend to fly solo. I did Monday and made these notes: "It was quiet at KVDF, a few planes in the pattern but definitely not the volume of planes flying at a healthy airport. I did a T&G AT X39, went up to Pilot Country, wandered over to KPCM (closed for repairs) did some ground reference maneuvers and headed home. Radio was nearly silent. Except for a few “radio checks” I spoke to no one. Restored my soul. Safe arrival KVDF."

I plan to fly as often as I can. Its great to get away from the COVID-19 news.

BTW: just an amateur observation: The two curves we always see show an early peak if we do nothing and a lower peak (extended in time) if we follow the government guidelines. That's important so that our healthcare system can handle the load. But the area under both curves is the same. So the same number of people are going to get the virus. If you are in an endangered group you are hoping that by reducing the peak you are giving hospitals time to find you a bed and our researchers time to find a cure to change the curve completely. Come on J&J!
April 9th, 2020: an update.

As the United States enters a period that administration health officials are saying could be the strongest wave of COVID-19 infections yet, we’re hearing more and more reports of aircrew members falling ill with the virus. Unions representing flight attendants have begun to share that many members have tested positive. And the numbers are concerning. Plane and Pilot

I've received requests from my students returning from college wanting to book training slots for the summer. I told them I cannot open my schedule until there is evidence that the pandemic has subsided or our medical researchers have developed an acceptable prescription to alleviate the symptoms. I will checkpoint with them in June.

April 11th, 2020: an update.

A flight school in Florida recently had the police show up at their facility and told them they needed to terminate all operations, in spite of the fact that they had enhanced cleaning methods in place, and screening of staff and students. They contacted their attorneys and are currently still operating in a limited manner after that interaction. The school specifically stated that if they are forced to close, they will be closing their doors permanently if they need to close more than 30 days.

The state of Maryland has similarly told providers of flight training that they must stop their efforts. Two training providers (both operate multiple aircraft) have indicated that they will be closed permanently if they are prohibited from operating more than 30 days.

An FBO that offers training in Pennsylvania reported that they were told by local officials that they must terminate any in-person flight training in aircraft. When they indicated they would close the business as a result, they were told that they couldn’t do that and had to stay open because they were also the provider of fuel at the airport. Their airport management indicated to them that they must keep that service open or they would terminate the FBO’s airport operations contract. What’s a Flight Instructor to Do Now?

BTW: Another amateur observation. Last month all of the discussion was about "flattening the curve". Our social distancing was done to insure hospital beds and medical personnel would be available to take care of the sick. Now the talk has changed and is about keeping people from getting sick at all (even if the hospital will not be overwhelmed.) I would like to make my own call on this new strategy. I'll "keep my distance" but would like the option to go have a pizza (or fly with a student) if I want too. 
April 14th, 2020: an update.

“I don’t know of a magical date when everything would be okay again,” said Cindy Prins, an epidemiologist at the University of Florida.

And yesterday, the state's surgeon general, Scott Rivkees, warned we can't expect it anytime soon: Floridians might need to practice social distancing and wear face masks until a COVID-19 vaccine exists, which could take a year.

“Until we get a vaccine, which is a while off, this is going to be our new normal and we need to adapt and protect ourselves,” he said.

He was then whisked away by the governor's spokeswoman. Watch the video here.

In Hillsborough, a curfew and confusion. Hillsborough County has enacted one of Tampa Bay's most stringent pandemic measures: A curfew from 9 p.m. to 5 a.m. is now in effect.

Officials want to curb large gatherings to slow coronavirus infections. But can residents jog or walk their dogs? That is still unclear.

What is clear is that residents soon will have to wear face masks when conducting essential business. The county’s Emergency Policy Group likely will pass the measure Thursday. Tampa Bay Times.

In aviation we’re often faced with the questions of could versus should. The FARs provide a baseline of could, but it’s our training in aeronautical decision making and our past experiences shaping our judgement that decide should. AOPA

April 16th, 2020: an update.

During last year’s flu season, according to the CDC, 490,561 people in the U.S. were hospitalized due to the seasonal flu virus. The prior year, it was 810,000 flu hospitalizations. This explains why, as we noted here, America’s hospitals have not been overwhelmed by the number of Wuhan flu sufferers, not even in New York City. The number of COVID-19 hospitalizations falls well within the natural variability in flu hospitalizations that we always see from year to year. Powerline blog

April 17th, 2020: an update.

According to the sheriff's office, response teams were called to the business multiple times after getting complaints on April 3, twice on April 7, April 10 and April 16.

During those calls, deputies say Wood was issued several warnings but refused to close the store and became argumentative.

On Thursday, deputies say Wood again refused to close and was arrested around 6 p.m. He is charged with operating a non-essential business and traveling to operate a non-essential businessarrested for violating safer-at-home order

My April 17th email to all students:

I hope you are all well and taking precautions to stay that way. My family is fine, although weary of "hunkering down" and the weather has been lousy for exercising Sally. Hopefully, it will get better this week.

So Hillsborough County still shows an increase in cases each day but the rate of change seems to be decreasing. This is good news. However, I'm trying to determine when we can start flying together again. Previously I could let my students use their best judgment by using IMSAFE. That doesn't work anymore, There are too many asymptomatic carriers that would pass that test. How do I judge when it is OK to let someone in the cockpit with me? Until I get better guidance I plan to use the Federal Gating Guidelines as the primary reference for my decision. (see attached.) I will use the Hillsborough County daily statistics as my data source. (LINK)

These changes will also be made to our normal flight ops:
  1. We will meet at my hangar rather than the FBO. Preflights, briefs and debriefs will be done there to avoid unnecessary contact with others. I will provide the gate code.
  2. I will no longer provide a headset.
  3. Only one flight will be scheduled per day. With the summer heat coming upon us that flight will probably start at 9:00 AM or sooner. As always we will not fly in temperatures above 90 degrees.
  4. Students will provide their own supplies for cleaning the cockpit prior to and after each flight.
My next status will be on May 2nd. I would appreciate any ideas or inputs you may have.

April 27th, 2020 an update:

My school is still closed. I've bee watching the statistics for Hillsborough Country to see if we have "reached the peak." We currently have 1028 cases, an increase of  7.7% over last week. Not quite there yet.


3 Coronavirus Facts Americans Must Know Before Returning To Work, School.
  1. Fact 1: Staying home saves lives but it doesn’t kill the virus. As I stated earlier, the area under the curve is the same. So staying in my house doesn't kill the virus however it does make it less likely for me to catch it. 
  2. Fact 2: We’re in this for the long-haul. The coronavirus will persist until there is either (a) a safe vaccine (still 12 to 18 months away) or (b) until there is “herd immunity,” whereby two-thirds of the nation (about 200 million people) must become infected, recover and develop the appropriate antibodies. This, too, will take at least a year. I can't wait for either one of these two options.
  3. Fact 3: Our nation is ignoring the most important metric: R0 (pronounced “R naught”) is a number that indicates the contagiousness of an infectious disease like COVID-19. Specifically, it tells us the average number of unvaccinated (or otherwise vulnerable) people who will contract a disease from one contagious individual. Early data suggests the R0 of COVID-19 is between 2.5 and 3.0. However, the actual number depends not only on the biology of the disease but on the actions people take. So I plan to take actions to to limit the way I might get this thing. Masks, gloves, in depth cleaning and of course, washing my hands.

I went flying today (solo). I didn't talk to anyone on the ground. I made my normal position reports in the air. It was about 1.3 hours of not thinking about this $@(&*.

My May 3rd, 2020 status to all students:

All,

I believe we have a much better understanding of the pandemic and its impact on our society. I also think opening up the lockdown is a good idea however, I'm not ready to do so just yet.

Hillsborough just had a large spike this weekend with nearly a 20% week to week rise in known cases. I think this is mostly due to increased testing but regardless it shows the virus is still very active in our community. Wear your mask, wash your hands, be safe.

My family and I are doing fine. I fly Sally regularly (solo) to keep her exercised and myself proficient. The pattern at KVDF is pretty quiet. I miss flying with you.

I'll provide a new status on May 16th.

May 7th, 2020 an update:

From NAFI:

"Good Job, Jack Pelton
One of the lessons we teach our students is the art and science of aeronautical decision-making. As defined by the FAA in AC 60-22, ADM "is a systematic approach to the mental process used by aircraft pilots to consistently determine the best course of action in response to a given set of circumstances."

When you read EAA CEO Jack Pelton's announcement that AirVenture 2020 has been cancelled (see below), that is precisely the process that was followed by that organization. It had to have been a very difficult decision, knowing the emotional impact that it had on the aviation community along with the economic consequences for both EAA, the industry, and the Oshkosh region, and I'm sure all of that was taken into account."

"My conclusion is, like in any good flight planning, don't take the risk. Therefore, I have no choice but to cancel AirVenture 2020. Together, we can come back stronger, safer and ready for AirVenture 2021 and create a memorable world class aviation event. Because of our dedicated and enthusiastic EAA members, our Association is strong. We know that at some point this storm will pass. And over the next 12 months we will continue to support all of you as we again, together, grow EAA in the Spirit of Aviation." ~Jack Pelton

May 20th, 2020 an update:

To my students:

Hillsborough County still shows an increase in cases each day but the rate of change seems to be decreasing. As of May 17th, the week to week change has been +10% in reported cases, most of which coming from nursing homes. So while the virus is still active in our community I believe we can move forward with caution. I plan to partially open the school on June 2nd unless we see a spike in new cases. I will not do any Discovery Flights but otherwise maintain a normal schedule.

Some of you may feel it is still too soon to start, in which case please don't schedule until you are comfortable. If you work in an area where the risk of infection is already high, please don't schedule. 

These changes will also be made to our normal flight ops:
  1. We will meet at my hangar rather than the FBO. Preflights, briefs and debriefs will be done there to avoid unnecessary contact with others. I will provide the gate code.
  2. I will no longer provide a headset.
  3. Only one flight will be scheduled per day. With the summer heat coming upon us that flight will probably start at 9:00 AM or sooner. As always we will not fly in temperatures above 90 degrees.
  4. Students will provide their own supplies for cleaning the cockpit prior to and after each flight.
  5. I will no longer supply a seat cushion.
Please contact me with any questions.

This morning I read this in my local newspaperOne day before a top Florida Department of Health data manager lost her role maintaining the state’s COVID-19 data, she objected to the removal of records showing people had symptoms or positive tests before the cases were announced, according to internal emails obtained by the Tampa Bay Times.

The dashboard that Jones managed is the best official source for in-depth data on how the deadly pandemic is moving through the state. Studying it is the surest way to know where outbreaks are growing and where testing is being done. Without access to the data, Floridians would have to rely on the word of officials and politicians without being able to verify for themselves.

So the data I use to make my Go/No Go decision my be corrupted.


May 25th, 2020 an update:

Lockdowns failed to alter the course of pandemic and are now destroying millions of livelihoods worldwide, JP Morgan study claims. JP Morgan research said infection rates had fallen since lockdowns were eased. It suggested the virus 'has its own dynamics' which are 'unrelated' to lockdowns. Report said they were imposed with little thought of 'economic devastation'

Author Marko Kolanovic, a trained physicist and a strategist for JP Morgan, said governments had been spooked by 'flawed scientific papers' into imposing lockdowns which were 'inefficient or late' and had little effect

June 3rd, 2020 an update:

Dr. Anthony Fauci now says that a second wave of COVID-19 may not even happen and that wearing a mask is largely symbolic at this point. Link

I opened the school and flew with a student yesterday. We exercised COVID19 safety recommendations and flew a normal training flight. It was great to be back to work.!

June 9th, 2020 final update:

Preliminary evidence from the earliest outbreaks indicated that the virus could spread from person-to-person contact, even if the carrier didn’t have symptoms. But WHO officials now say that while asymptomatic spread can occur, it is not the main way it’s being transmitted. 

“From the data we have, it still seems to be rare that an asymptomatic person actually transmits onward to a secondary individual,” Dr. Maria Van Kerkhove, head of WHO’s emerging diseases and zoonosis unit, said at a news briefing from the United Nations agency’s Geneva headquarters. “It’s very rare.”Link here

I went to my Doctor yesterday for a visit. My blood was taken for routine analysis. I asked them to check for the COVID antibodies.

A New Angle

Video Link: A New Angle

A new student and I sat in the runup area for RWY5. He was going through the checklist and I monitored the results as he tested the mags and carb heat. It was a busy day at KVDF. A lot of flight schools trainers were doing their circuits and my attention occasionally got diverted to watch them land.  I looked over my student's shoulder to make sure the canopy hooks were in place and then turned to check my own. Out on the runway, all was not well. A plane fouled the right side of the runway, tail sticking straight up in the air. I called on the CTAF to let the busy traffic pattern know that RWY5 was now closed. We went over to RWY36 and took off from there.

I spoke to the airport manager once we got back. A student on her first solo had porpoised and botched the landing. She is fine but the C150 was totaled. I hope she can "get back on the horse", but I doubt it.

In other events, my CFI insurance is up over 20% this year.

I started working with Jeff, a "snowbird" down for the winter trying to avoid the brutal Illinois weather. His Sting experienced an ADSB failure and I helped ferry his plane from SRQ to VDF. We did some testing, worked with the expert on the phone at Garmin and eventually decided to take to the great folks at Gulf Coast Avionics at LAL. We used the ADAPT flight plan app to fly in the Tampa airspace.  Josh took most of the afternoon readjusting the settings to correct the problem.

I'll work with Jeff to help him get his Sport Pilot license before his winter stay in Florida ends. Jeff just passed his Knowledge TEST!

One student has been practicing short field landings. The ACS states:
Touch down at a proper pitch attitude within 200 feet beyond or on the specified point, threshold markings, or runway numbers, with no side drift, minimum float, and with the airplane’s longitudinal axis aligned with and over runway centerline.
How do you measure that? I added a new camera mount to the bottom of the airplane and made a test flight. The video referenced above shows the results. Each centerline stripe has a standard length of 120'. Each space between the stripes is 80'. (The size of the painted runway designation numbers should be 60 feet tall and 20 feet wide.) Link

So, if your intended point of landing is the beginning of the stripe, you must touch down PRIOR to the beginning of the next stripe.




(Watch the video and tell me how I did.) I have gotten a bit busy. The school has seven students now, most are scheduled once a week. The winter weather has been good and Sally is holding up well. (Brakes and tires are keeping me busy.)

And most importantly, we are having fun.

ADSB-Out

It was mandated. All airplanes flying in controlled airspace* must be equipped with "NextGen" ADSB-out equipment. *the ADS-B mandated airspace defined in 14 CFR 91.225 (above 10kft MSL in Class E or within the boundaries of Class B and Class C airspace) including the 30-mile veil. 
An ADS-B Out transmitter alone is not sufficient to meet the requirements of 14 CFR 91.225 and 91.227. Aircraft must be equipped with a Version 2 ADS-B Out transmitter and a compatible GPS position source. There are two types of ADS-B systems available:
  • Mode S transponder with Extended Squitter, referred to as 1090ES that meets the performance requirements of Technical Standard Order TSO-C166b
  • Universal Access Transceiver (UAT) that meets the performance requirements of TSO-C154c. UAT has the additional capability to receive weather data provided by the FAA ADS-B network and operates on 978 MHz.
Due to the S-LSA restrictions previously discussed, my new mode S transponder with Extended Squitter,  (1090ES), is a Garmin GTX 335. Since the new transponder has the same dimensions as the old, I ASSUMED  it would be a simple "plug and play". Nope.


  1. The new mounting box screws did not align with the avionics tray. New holes had to be drilled in the tray. Not trivial if you don't have a right angle drill.
  2. The mounting mechanism has moved from the center of the old transponder to the right on the new. The instrument panel had to be trimmed to accommodate this change.
  3. The old connector (from the Dynon D100 EFIS) would not fit the new transponder. We did a deep analysis of the old versus new pinout to determine what pins had to be added to the new connector. (This would provide the RS232 altitude information.) New pins were soldered and inserted into the new connector.
  4. A new GPS antenna is required which meant a new custom cable had to be built. Holes were drilled through the skin in front of the canopy and the cable was connected to the new transponder.
Thank you CERTUS!

Ready to fly? Nope. It also has to be programmed. This is done by holding the ENTER key while turning the unit on. This brings up a series of configuration menus.  Most are fairly straight forward but some require knowledge greater than mine. Fortunately, there is YouTube, right? That didn't get the job done. Test flights showed that it wasn't working properly (Thank you Tampa Approach for being so patient.) I needed an expert and found Mike. Call Garmin G3X support at 866-854-8433. The last problem was a SIL failure (Source Integrity Level). Mike took me through all of the configuration options and found that I needed to change my "UNK" to IE-7. (Yeah, that doesn't mean anything to me either.)

But it works.  I am 2020 compliant!
