henrylzy 0 Posted June 11, 2021 Share Posted June 11, 2021 This happened at around five hours after airborne, the aircraft start climbing on its own, from FL360 to a max of 47176 feet, while the speed was stable. Then after a short while, the speed was dropped to 152kts from 301kts, as shown in the screen shot below, and the altitude was dropped to 23364 feet. It all happened while I was sleeping, and this was not the first time the aircraft behaving like this. The aircraft's AT was still on CLB when I woke up, and the FPS was really low(5-10 fps).
