The GDU displays radar height when a radar altimeter is interfaced to the system.
Radar altitude displays to the left of the altitude tape. The RA altitude field
automatically displays when the aircraft is within operating range of the installed
radar altimeter unit (generally 2,500 ft AGL).
Brown and white hash marks depict a ground awareness band on the altimeter tape.
When the radar altimeter readout is 0 ft, the ground band will level with the altitude
pointer.

Depending on configuration, an audio alert is active when the radar altimeter
indicates the aircraft is descending below 100 ft.
