Entegra EX5000 -25- 600-00108-000 Rev 07

1) Range Annunciation—The range number indicates the currently

selected range as selected by the Range knob. The supported

ranges are 2.5, 5, 10, 20, 40, 80, 160, 240, and 320 nm. At start

up, the EX5000 TAWS range defaults to 80nm.

2) Display Orientation—This annunciation describes the

orientation of the TAWS display. If heading is available to the

EGPWS, the TAWS display orientation is “heading up”, with the

aircraft's heading to the top of the display. HDG ### MAG

displays, where ### is the aircraft's magnetic heading as reported

by the EGPWS.

If Heading is lost or not available to the EGPWS, the EGPWS

may use magnetic ground track instead, and TRK ### MAG

displays, where ### is the aircraft's magnetic ground track.

In certain locales, such as near the magnetic poles, magnetic

variation may become unreliable. The Display Orientation will

switch to the “true” value, for example, HDG ### TRU or TRK ###

TRU.

If neither heading nor ground track is available, the terrain will be

replaced by the cyan message “TAWS Display Unavailable”.

3) Scan Marker—The marker is a short white line that moves

across the top of the display area. It indicates the current position

of the scan.

4) Peaks Mode Elevations—Appears only when your EGPWS has

been installed with the “Peaks Mode” option selected. The two

numerical values correspond to the highest terrain/obstacle

elevation displayed and the bottom elevation of the lowest color

band displayed. Elevations are expressed in feet above sea level,

with the hundreds digit displayed half size, i.e. 108 is equal to

10,800 feet and 010 is equal to 1,000 feet.

If there is no appreciable difference in elevation (flat terrain) only

the highest value displays. The color of each elevation value is

the same as the color of the terrain display containing that

elevation (green, yellow, or red). During a terrain alert,

threatening terrain will be displayed as bright red and/or bright

yellow. The elevation value colors are not modified in this case,

but continue to correspond to the colors that would appear in the

TAWS display under normal circumstances, and represent the

actual elevation of the terrain relative to the aircraft.
