ALT 1: Absolute altitude

ALT1 is your altitude above Mean Sea Level (MSL). Toggle between displaying ALT1 and ALT2 by pressing A1 / 2. ALT1 is automatically set to your GPS altitude as soon as the Element Speed acquires a GPS signal. This altitude calibration means, of course, that the QNH pressure setting is also automatically adjusted.
