My apologies for not being more specific, but along with what posted above I'm flying the a321 I believe it's the lufthansa model, cold and dark. managed mode . Right after takeoff, gear up I egage the AP; sometimes it will track the "step by step" flight plan other times it will not. I use a Saitek x52 I think it is, but it's a separate throttle and joystick. I will have to check if any switched or buttons could be interfering withe the autopilot. I will also try reinstallling Airbus X. Question, when the AP is on, the 5th colum in the FMA shows the AP on in white letters. Is this the correct color to indicate the AP is on?
Thanks again for the response
