I think you may be on to something, there, guys. Makes sense."Miss-key", or a binding problem could absolutely be a probability.
I don't manually actuate AI Pilot. I have it bound to a 4-way on my throttle, and it may be bouncing the "A", or perhaps the delay is long enough for the game to see the "A" as a stand alone key press. Being bound to a very common, single letter such as "A" , for someone like me with many, many
HOTAS bindings is like asking for problems me thinks.
Going to re-map AI pilot to a single function button and re-map "auto-trim" to a less common and more complicated Key-press (maybe a three key combo)in game.
See how it goes, but that may be it.
Very much appreciate your thoughts on this.
