Recently I’ve encountered an issue on the A350. It occurs at the beginning of the flare phase. Without any input on the thrust levers, the A/THR automatically switches from normal active mode to armed mode (FMA A/THR changes from white to blue). At the same time, the FMA throttle mode changes from SPEED to MAN THR, and the thrust increases from the normal approach N1 (51%) to 86%. It feels as if the system is forcing a go-around. I’ve experienced this twice: the first time during a very normal and stable flare, right after passing 50 ft. The second time happened when the aircraft was descending with a relatively high sink rate. I checked the A350 FCOM but couldn’t find any explanation for this behavior. Has anyone else experienced the same issue? Is this a bug or something else?
