REL (Relative Altitude) Display
The REL (Relative Altitude) display mode shows the terrain above and
below the aircraft’s current altitude, regardless of climb or descent rates. It
is most useful to answer the question of what is “above” and what is
“below”; and also, what is “somewhat” below.
During an alert this display will be automatically selected and shown in
ARC view unless the pilot has previously selected TAWS INH.
The display mode may be overridden by the pilot after the automatic
switching occurs.
