Okay this may be normal to some people but for me this caused my 747-8 to smash into the ground,
I was on inbound into KCAE and my HUD altitude was saying 1,200ft whist my A/P Altitude was set to 2500ft i was so confused plus the visibility was below 4km
I saw the terrain just below me and realised i was atleast 800ft above it my speed had already dropped to 160kts and as soon as i turned A/P off to climb I plummeted. This just really p’d me off coz i nearly finished my 30min flight
Why did i have two different altitude readings and why did my plane become so low?
