It's the STC process first. Then the AML.
I think Dynon did the 172 STC and then all the other models on the AML. The STC process is paperwork with the FAA. You can read about it on the FAA website.
I was hoping for a shorter answer than reading something on the FAA website.

Interesting information here. Like I said, I actually get my RPM down to 2250ish and see about 9.9 GPH and 143 knots true.
I might start playing with the prop and see what speeds I get at 2100 RPM.
-
What do you guys find the best RPM for speed and fuel efficiency at altitudes of 6500 to 8500’?
Whats the lowest RPM you’ll use in cruise at full throttle at those altitudes? I’m usually around 2230 to 2250 RPM and wondering if I should or can go lower to save a little bit of gas.

I predict a 3Q or 4Q 2023 certification of the M20 AP. My two cents.

It would be a shame that after all the work and effort BK made towards getting the Aerocruze STC’d that they end up with dismal sales numbers due to lack of confidence amongst customers. Looks like a great product (if you could get one).

There are probably different levels of work that needs to be completed for the FAA to sign off on various STCs…
For the GFC500 AP… Garmin was enlisting MSers to support the project with their planes…
One of every model was actually being used for a few weeks…
An AP is more complex than a single radio…. Some of that complexity was mounting brackets for each model, wire runs, and chain drives….
So… the answer is… it probably depends…
But, the STC writer will have that conversation of requirements with the FAA as the project gets started…
a great question to ask if you have a Howard Aircraft and aren’t sure about an STC you are purchasing…
The installation information probably has the serial numbers of the planes used to write the STC and AML…
PP thoughts only, there is a lot of similarity with the big Gov three letter organizations…
It may be wise to ask your favorite Dynon guy… if this question is related to Dynon…
Best regards,

This question was more out of curiosity more than anything. I was looking at the AML and some of the aircraft I don’t even recognize. I had to Google the Howard DGA-11 and the Nardi FN-333. I knew Nardi was an Italian manufacturer that once made Hughes model helicopters under license in the 70s and 80s but that’s it.
I can’t imagine there’s a old Hughes biplane flying around somewhere with a Dynon Skyview in it but then again, I could be wrong.

Being that there are smarter people than me on here, does anyone know how the certification process works to build an AML for a particular piece of equipment? For example: The AML for the Dynon Skyview HDX includes over 600 different airframes and some of them are pretty obscure aircraft such as the Howard Aircraft DGA-11, Mooney M22, Nardi FN-333 (All of 29 ever made), PZL M26 (9 made), etc. Does this mean they installed and tested a Dynon Skyview in each airframe or do they determine that two airframes are similar enough to sign-off on an approval for multiple different airframes?
Same with the Garmin GFC 500. There are currently 28 different models of airplanes with numerous subvariants. I’m guessing not all the subvariants are tested for each model.
Does anyone have any insight on the certification process? I’m very curious.

How do you know that GA pilots don’t have higher rates of all these conditions? One of the problems with studying small exposures and long-term effects is that you have to follow a lot of people (or animals) for a long time to quantify the effects.
For example, we know radiation is bad but we don’t know how bad. Most of our data on this comes from Hiroshima and Nagasaki but we don’t have good studies to show how this compares to ultra short exposures to high radiation environments (like a CT scan). To quantify this we would need to follow hundreds of thousands of people for their lifetimes in order to determine what effect the radiation has on their risk of cancer. We can’t do that. So we’re stuck knowing there is a risk but not how big that risk is. We do know that any level of radiation exposure can increase cancer risk and that higher radiation exposures further increase this risk so instead we try to expose patients to “as little as possible” in terms of radiation (and maybe use ultrasound or MRI instead of a CT or not get a CT at all if the risks don’t seem to justify the benefits).
Lead is the same as radiation. There is no safe established level of lead so (putting my public health hat on) the goal should be to expose people to “as little as possible.” I wear gloves when I sump the tanks, wash my hands afterwards and I barely smell the fuel (I was a chemistry major so I’ve received specialized training in smelling things). I don’t let my son sump the tanks, touch the gas caps or fuel the plane either.
I know facts don’t matter these days, but the association between lead and harm is well established and so is the association between people around GA airports and lead levels.
I certainly can’t tell anyone how they should spend their time, but as my wife (a psychiatrist) often tells her patients “is this really the hill you want to die on?” You really want to be the last person supporting leaded fuel when there is clear evidence of harm just because you (and I don’t mean you personally, @NotarPilot) are a cheap ba$tard? If $1-2/gal prices you out of aviation then you probably should pick a different hobby.
Studies no one will read:
https://pubmed.ncbi.nlm.nih.gov/24261063/
https://pubmed.ncbi.nlm.nih.gov/21749964/
https://pubmed.ncbi.nlm.nih.gov/16181659/
You bring up many very good points. At the very least I will be wearing gloves when I pump and sump the gas.
As far as the studies go, you’re right. I guess I just assumed there would have been a study of leaded fuel and the effects on GA owners and pilots. Hell, it seems like there have been studies on everything else on this planet, why not that?

Funny - I was thinking of that Shakespeare line too. It's not the FAA that keeps GA stuck in the 1950's - It's the Owners still longing for that Chevy Bel Air that cost $2,166 new, no seat belts, no pollution controls, vacuum tube radio and all....
Which is why Cirrus is the most successful single engine piston manufacturer in the world.

100Ll has a tremendous amount of lead in it which isn’t good for anyone. The goal here should be finding a good solution that doesn’t require lead.
I’m not trying to be smart here and this is a sincere question but if lead based aviation fuel was this tremendous danger to people wouldn’t small GA piston owners and pilots have demonstrably higher levels of cancer, anemia, weakness, and kidney and brain damage than the rest of the public that isn’t directly around this stuff? I know some of you may argue, based on my previous posts, that I’ve suffered some brain damage but let’s think of me as the outlier.
Any of you ever get a little bit of a gas on your hands or fingers while sumping the fuel out of your tanks before a flight?

The more I read about Turo the less I am inclined to move forward with this. I just see too much risk and liability. I think to do it right I would need to form an LLC just to register the cars with to protect my assets. I’m just not that much of a risk taker for this.

Wow! You got completely blocked??? That’s ridiculous. The Aerocruze option is looking like a very bad option especially if you must go through Duncan to have it installed. I’m happy to wait for Dynon to get the STC done for my SkyView system. Luckily the HDX makes hand flying and IFR flight really really easy so I’m in no hurry.

Have you talked to @kortopates? That’s in his neck of the woods. Reminds me of a cartoon I saw in the Union-Tribune when the Mexican cops were stealing American cars. The question was “How does a Mexican cop stop your car?” And the answer was “he steps on the brakes!”
Interesting article. Just goes to show, you get what you pay for.

I’d be into it. I”ve used Turo 3 times. 2 of my 3 experiences were perfect. I just did a 4 day backpacking trip in the Sawrooths. I TURO’d an Outback for 5 full days for $61 a day. It was parked in short term parking at the Boise Airport less than 100yds from baggage claim. Lockbox on the driver side window. So much easier and faster than rental car BS. I check TURO first and the rental car companies second. I would think that the number of AirBnBs in the area would be a good indicator of demand for a Turo rental.
Thank you for your input as well as everyone else’s. The airport I’m considering to start out at would be San Diego Brown field (KSDM), which seems to lack an on-site rental company and seems to get a decent amount of traffic that would likely make it a little profitable.

FYI two more airports in the area were hit. Poplar grove and one other
Just curious, how did they get in your hangar? I have a combination lock on mine. A few trusted people have the combination and I’ve never had an issue. Sorry to hear this happened to you. I trust your insurance will cover the loss?

There is a website that lists airports with FREE cars.
https://www.airportcourtesycars.com/
Local airport does not have one, but if someone is around, they will give a ride. Or there is a nearby Enterprise to rent one.
There used to an airport nearby that had an old beater, free for use. If the gas was low, you would stop and put a few gallons in. The muffler fell off, so some pilots got a replacement went over and replaced it.
Just some info.
Not sure if I would use a paid courtesy car versus a Lyft/Uber
I think these examples are few and far between.

You can't get an Enterprise car for $30/day any more. The last one I got ( a month ago) was more like $90...
Yeah I agree, just like you can’t just a 150 for $30 an hour anymore.

If done right, it might work. If I knew there was a (some) vehicle(s) available at the smaller airport where I wanted to stop, I would gladly Venmo or Zelle a reasonable amount to the owner and use it to go eat lunch etc.
Establishing a price, advertising the availability, and factoring in the deadbeats who would take advantage might be a daunting task. Add in the problem of who is going to maintain it (flat tires, oil change, semi-cleanliness, etc.) and it could get tough.
Perhaps if enough guys who hangar at one of those fields put a car at his place and spread the word....
What is the consensus of our group about what they think would be a reasonable price, and how they would handle the fuel.
I’ve only rented a Turo once but I liked how the platform is set up. You take photos of the car, the dash, the fuel gauge, etc. You pay through the app and Turo keeps a portion of 15 to 40% depending on the level of “protection” you want, kind of like insurance only they don’t call it that.
I would like to see the option, on Turo, of being able to rent it for less than a day. I’m not sure that’s an option. But maybe something like being able to rent it for 2 or 3 hours to go get lunch or run an errand.
And the deadbeats you mention would certainly be a concern of mine. I also believe that doing it right might involve registering the car under an LLC to protect you and not registering it in your own name.

I’m considering possibly venturing into this side hustle by buying a car and leaving it at a local airport to make it available for GA pilots to use when there isn’t a car rental option at that local airport. Do you think this would be beneficial for GA pilots? I know that location plays a big part in where to station the car(s) but do you find that getting ground transportation to be one of the biggest challenges when visiting smaller airports?

One of the crew (I think the PI) was on the news talking about it and they played a short clip from the vid below. He said they were in one that was comparable in 2019 but this may have been worse.
Call me crazy but I would love to go for a ride on one of those flights just once in my life. My coworkers think I’m crazy because I actually like turbulence and wind. I think the highest I saw the wind get coming off a mountain on the Ol’ G500 was 58 knots. I’ll admit though, I flew away from that area as quickly (not fastest) as possible.

Question: Does the FAA send you a new airworthiness certificate when you change your N number or just a new registration? I changed my N number and finally got my new registration card but the airplane still has the old airworthiness certificate. I can’t find anything online saying I’ll get a new one.

I bought it on YouTube about 2 months ago. I’ve watched it several times and the dogfight scenes even more times with my son. He really enjoys it even though he doesn’t like flying in the real plane. I think it was $25 to buy the movie.
