PEAKS MODE
This is a feature provided only by EGPWS version 216 and, when
selected, adds additional density patterns and level thresholds to the
standard mode display levels and allows the terrain to be displayed
during the cruise phase even if it is more than 2000 ft below the
airplane.
When the Peaks display is on, elevation numbers indicating the
highest and lowest terrain/obstacle currently being displayed are
shown on the display. These elevations are expressed in hundreds of
feet above sea level (MSL) with the highest elevation on top and the
lowest on the bottom. In the event that there is no appreciable
difference in the terrain/obstacle elevations, only the highest value is
displayed.
The color of the elevation value displayed matches the color of the
terrain displayed.
If the airplane is 500 ft (250 ft with landing gear down) or less above
the terrain in the displayed range, the peaks color displayed will be
identical to the terrain awareness display mode, with the exception of
sea level displayed as cyan.
