QFE corresponds to which altitude type?

Indicated altitude Absolute altitude True altitude Pressure altitude

Correct Answer:

Absolute altitude

Explanation:

QFE sets the altimeter to the pressure at the airfield surface, so the instrument uses that surface as its zero reference. The readout then shows height above the airfield itself, i.e., the altitude above the ground (absolute altitude, or AGL). On the ground it reads zero, and as you climb, the display increases by the height you’ve gained above that field’s surface. This is different from setting QNH, which makes the altimeter indicate height above mean sea level (true/AMSL), and from the standard 29.92 setting used for pressure altitude.
