MK V & MK VII EGPWS Pilot Guide
When a caution alert is triggered, the terrain (or obstacle) that
created the alert is changed to solid yellow (100% density) as
illustrated below.
When a warning alert is triggered, the terrain (or obstacle) that
created the alert is changed to solid red (100% density) as
illustrated below.
NOTE: When a TAD caution or warning alert is active, the
display image (cells) surrounding the target are enlarged
(surrounding cells are illuminated). This allows a smaller
terrain or obstacle (e.g., a single tower) to be better seen on
the display.
The transition between green and yellow is below the aircraft in
order to account for altimetry and/or terrain/obstacle height
errors. Also, the transition altitudes between colors are biased
upward proportional to the descent rate when greater than
1000 feet per minute. This provides approximately a 30
second advance display of terrain.
