Q Code Description
QFE
Atmospheric pressure at sea level, corrected for temperature and
adjusted to airfield elevation. When set on the altimeter it reads
height.
QNE
Atmospheric pressure at Sea level in International Standard
Atmosphere (ISA) 1013.25 mbar.
QFF
Barometric pressure at a place, reduced to Mean Sea Level (MSL)
using the actual temperature at time of observation as mean
temperature.
QNH
Atmospheric pressure at Mean Sea Level (MSL) (may be local,
measured pressure or a Regional Forecast Pressure (RFP). When
set on altimeter it reads altitude.
Selecting a task exits the menu and
