2.10 Radar Altimeter

When an optional Radar Altimeter is installed, the altitude received from the
radar altitude will be displayed on the PFD.
NOTE: See the Radar Altimeter documentation for details on the radar
altimeter performance and limitations.

When the radar altitude is 0, the brown band will be level with the altitude
tape pointer. As the radar altitude increases above 0, the brown band will move
down the tape in an amount equal to the current radar altitude.

The Radar Altimeter self-test process will be annunciated on the PFD above
the Radar Altimeter altitude value. The self-test is a wiring test to indicate
communication between the GDU and the Radar Altimeter. The self-test will be
cancelled after 15 seconds, the Test key is pressed again, or you leave the System
Setup page.
