@plumps said in A/T and Autopilot not engaging:
If you wait ages (>10 minutes) [...] all the AP/TPR/YD systems start to work again.
well, indeed. I let it sit today reeeeally long and voilá, A/T showing green lights and good to go. will double check soon. no idea though what's going on in the backgroud when one flight A/T starts readily engaged and one time not. with very same Rj85 Lufthansa livery (official) and at the very same airport.
BTW, clicking the fly now button as soon as it turns yellow/can be clicked did NOT do the trick, still A/T lights was grey and could not be enabled
