Sam Harris Posted May 14, 2023 Report Posted May 14, 2023 Hello everyone, I have an M20A and would like to add an autopilot The STC's on the Bendix King Aerocruze start with the B model - any ideas out there? Thanks, Sam Quote
chriscalandro Posted May 14, 2023 Report Posted May 14, 2023 Sell your airplane and buy one with approval for the autopilot you want. 1 Quote
kerry Posted May 15, 2023 Report Posted May 15, 2023 I have a Pathfinder P2A in my M20A. It was done with field approval by previous owner. There are M20A that came from the factory with autopilots but probably not what you're looking for. Quote
chriscalandro Posted May 15, 2023 Report Posted May 15, 2023 (edited) Field approval cannot be done for an auto pilot. It MUST be done as a one time STC, and unless you’re building your own autopilot, you won’t get the engineering info needed from the manufacturer. it requires an FAA engineering rep, an STC, even if only for one serial number of airplane, a ton of engineering data, and a ton of paperwork. if you have an auto pilot that was “field approved” I suggest you don’t say it publicly, and keep the name of who approved it buried deep in a log entry. a few of us tried to go this route for the Dynon autopilot.

Rwsavory Posted May 15, 2023 Report Posted May 15, 2023 And even if the Aerocruze were available it appears to be akin to the Ivory-Billed Woodpecker. 1 Quote

We were told many times long ago that autopilots could be approved under NORSEE, and that this would accelerate their availability to GA. Quote

I can tell you two manufacturers who thought that would work out for them. 1 Quote
carusoam Posted May 17, 2023 Report Posted May 17, 2023 See how far Big G has gotten with their AP… They were steadily working their way through the alphabet… The oldest was probably the 65 M20C… The M20A is slightly different from the M20C… The M20C already had the servo mounts from the factory from the Brittain system that was there originally…. Make contact with the Garmin factory… get on a list. Or make a list for them…. An AP is a wonderful thing to have for a plane…. Best regards, -a- Quote
kerry Posted May 17, 2023 Report Posted May 17, 2023 N1960 has a Brittain Accu-Flite. I believe Dan Morris installed it. I think Dan is on Mooneyspace. If you can contact him then maybe he can give you some details on how he did it. N1960 | 1960 MOONEY M20A on Aircraft.com Quote

I do not think he installed it. I believe he purchased the airplane already outfitted with the Accu-Flite but he does lurk on Mooneyspace so he may be able to chime in. The issue with any Brittain product is availability. They are scarce. You would probably have to spend many months to years cobbling together a system. The company is of course not making them any more either. Quote
