The B739 and the 777’s autopilot keep disconnecting mid flight 💀
I'm flying in A320 A380 B737 B777 B787 types on AeroFly, but I've never had such a problem, you should check if everything is suitable for autopilot to work.
An information for 737 and 777: If you are experiencing this problem during turns, adjust the heading switch from minimum to maximum or a setting close to it.
