Flight Level
Display
In aeronautics. The Flight Level corresponds to an altitude expressed in
hundreds of feet above the isobaric surface 1013.25 hPa, which allows all
aeroplanes in the world to fly alongside each other risk-free, irrespective
of the pressure values governed by local meteorological conditions.
Select the lower block using the button (it flashes), then
