is transmitted via 453 bus to the display.
(1) Functional Description and Operation
The terrain hazard display function enhances situational awareness by providing
a display of terrain-related hazardous situations in front of the aircraft on existing
ARINC 708A-compatible weather radar or EFIS flight deck displays. The display
may be either the EFIS Navigation Display (for EFIS-equipped aircraft) or the
weather radar display. A crew-activated switch is used to select/deselect the
terrain image on the display.
