Please add the information to the ticket, that ALL avionics are affected on ps5:
G1000, G3000, G5000, Honeywell, Boeing 737, etc… They are all affected, so it seems to be an issue of underlying mechnics of the game. Thank you in advance.
I also suspect this issue on ps5 also tied to it: https://forums.flightsimulator.com/t/autothrust-disengages-itself-randomly-on-ps5/
It might be a symptom of the same thing - or completely independent. I don’t know… but autothrottle is a subsystem of the avionics… so it might be tied.
