How do,
Had a very weird experience last night whilst flying my POSkY 747 out of Barcelona to LHR. I was just about to reach my nominated cruise altitude of FL30 when i got a master caustion light (yellow if i recall correctly) and a warning of sink rate. The wierd thing was i was nose up at an indicated 230kts and +1500VS.
Nothing i did could recover the aircraft, so the 747 was lost somewhere in the north pyrennees 😞
Does anyone have any idea what would cause this?
