Honeywell Bendix/King KMD 550 Pilot's Manual Addendum page 14

The most important function of the system is to provide the pilot with
easily interpreted information about terrain/obstacles relative to the air-
craft, and thus increase the pilot's Situational Awareness. In brief, when
using the Terrain Display during flight, the normal presentation of green,
yellow and red colors indicate:
GREEN colors Terrain/Obstacles are below the aircraft altitude.
Safe terrain/obstacle clearance is indicated.
YELLOW colors Terrain is very near or above the aircraft altitude.
THE AIRCRAFT DOES NOT HAVE SAFE TERRAIN CLEARANCE.
RED color Terrain is well above the aircraft altitude (at least 2000 feet higher!).
THE AIRCRAFT DOES NOT HAVE SAFE TERRAIN CLEARANCE.
THE AIRCRAFT MAY NOT BE ABLE TO ESCAPE THIS TERRAIN.
NOTE: Green colors indicating terrain/obstacles below the aircraft are
NOT shown when the aircraft is on the ground, to reduce display clutter
and to show only terrain that is significantly higher than the aircraft in the
departure area. Green colors will appear when the aircraft has climbed
approximately 500 to 800 feet above the elevation of the runway.
The following picture shows an example of the Terrain Display with the
flight plan data overlaid on the terrain data.
NOTE: This guide is not intended to provide all the details of proper
usage and interpretation of EGPWS information. Please reference the
Pilot's Guide that was provided with the EGPWS sensor for more infor-
mation.
