0 Radio Height
This quantity appears when it is less than 2500 feet.
- If a DH has been entered, the radio height appears :
~ in green when DH + 100 feet < RA < 2500 feet
~ in amber when RA < DH + 100 feet
If "NO" is entered as the DH on the MCDU APPROACH page, 0 feet becomes a default
value.
When the aircraft reaches the decision height selected on the MCDU, DH letters flash
amber for three seconds, then stay in amber above the radio height indication.
- If no DH has been entered or if both FMGCs fail, the radio height appears :
~ in green when 400 feet < RA < 2500 feet
~ in amber when RA < 400 feet
The radio altitude indication changes every 10 feet down to 50 feet, then every 5 feet
down to 10 feet, then every foot.

(~ Landing Elevation (blue)
~
The horizontal bar on the altitude scale shows the landing elevation at the flight-planned
destination.
It is displayed :
- during flight phases 7 and 8 and
- if the QNH reference mode is selected.
Ground reference
A red ribbon on the right of the altitude scale represents the field elevation. This ribbon,
which is driven by the radio altimeter signal, is displayed below 570 feet.
It moves up, as does the lower line of the attitude sphere, with the altitude scale as the
aircraft descends. When the aircraft has touched down, the top of this ribbon is at the
middle of the altitude window.
