TERRAIN AWARENESS DISPLAY
The GA-EGPWS can be interfaced to numerous types of cockpit dis-
plays. Graphical display of GA-EGPWS terrain and obstacle data is the
most important enhancement to Situational Awareness. This is especial-
ly true for lower performance aircraft. In addition to showing terrain
ahead of the aircraft, (depending on configuration settings and display
types) the system shows Geometric altitude (MSL/GSL), Magnetic
Heading or Track. The color and intensity of the terrain displayed instant-
ly alerts the pilot to areas of dangerous terrain and conversely to areas of
less precipitous terrain. Range of the Terrain Display is selectable by the
pilot from 1 nm to 320 nm, again depending upon the display type
installed in the aircraft.
The following figure shows the Terrain Display color patterns when the
aircraft is at lower altitudes, with terrain near or above the aircraft altitude
for the display range selected by the pilot.
