Help & Advice on an avionics upgrade path

[wslade2]

I have a Uavionics AV-30 and a couple years ago asked them to include Skymaster on their AML list when they went for their certification. I got an email from them advising skymaster was approved before I took delivery of my certified AV-30 and have spoken with them throughout certification process.
However, in terms of driving legacy autopilots discussed on this thread, it is of no help.

Show that email to the FAA ramp inspector and see how far it gets you. Or to the NTSB investigator after an accident/incident. You have an "Unapproved installation" which grounds your aircraft immediately, and threatens your pilot's license as well. I was castigated on this site for using non-PMA LED landing lights, but they were endorsed by the Bonanza Society, so I knew they were good lights. I understand the rules don't always make sense. But the risks are very different here. You best have a canopy cover whenever you park at a public airport. Prying eyes will cause you grief. The AV-30 is well-known in the aviation world, and most serious inspectors know its only approved for single engine aircraft. I don't agree with the logic, but I don't agree with the hassle it could cause either.

Don't learn the hard way.

Might be able to install under NORSEE as a AoA indicator, but I agree, not as primary replacement without bona fide STC via AML & permission letter.

I understand the comments and appreciate them.
I had noted their AML list did not include 337 when I checked their website few weeks ago and have been meaning to call them to see what's up. But the e-mail saying "Cessna 337 has been added to the AML list" exists. I just pulled it up again to check my memory. So I will call to clarify.
Avionics installer was also comfortable with it when we ordered unit and conferred with them.
However, with caution I have retained my OEM AI...plus it drives my legacy autopilot.
I believe my personal next step beyond the legacy stuff I have would be an Aspen and STEC autopilot.

I talked to some senior guys at Garmin recently. They intend to add 337 to G500txi Engine Indication System to STC and GFC autopilot. When?? “In the fullness of time” is what I remember thinking...

Just a brief note on support of the Garmin G5s - I have two installed, and it is integrated with my GTN750 and my OLD Century IIB autopilot - and it works great - I could only be happier once they STC the GFC500 for the Skymaster!!!

I have a bit of envy when seeing the GI275 in a friend's aircraft (cleans up panel nicely), however the large display and total functionality and safety of the G5 to an old aircraft is well worth the investment.

I will note that I did the G5 install myself (and integration with the AP) and it works great! I had to retain the horizon that drives the AP, and the G5 HSI integrates beautifully.

Let's keep pressure on Garmin to include the C337 on the GFC500 (or the 600) AML - they are including aircraft types that have far fewer airframes on the US register than the 337...I have let them know this by calling out those types!

P.S. Compare and contrast the 2 aircraft panels - one from 1948 and one from 1966... Pretty good for some 'old girls'

Jeff:

Quick question, did you have a new pilot side instrument panel made? I have the same year, just an earlier serial number, and my instruments are not lined up vertically like yours because the clock (same as yours) is mounted right above the yoke (factory hole) which pushes the bottom 2 instruments out so they are not directly lined up with the ones above. I will be installing 2 G5's this year and was wondering what to do about them not lining up vertically.

Thanks! Tom

Love your panel, I'm going to do the exact same thing with the mid cont m93 clock/USB + AV20s, as well as the G4 insight.
