News / Where is 'the first contact with the ground' of the Polish Airforce One [17]
QNH = height above sea level
QFE = height above point of measurement
So say Smolensk for instance. It's 720ft above sea level.
If the plane is on the ground, and the altimeter has the QNH pressure, it would read 720
If it is QFE it would read 0
is it possible the pilot got a false reading due to atmospherics and the fog ?
