5.3 TAWS Reference
5.3.1 Auto-Range
If the EGPWS has been installed with the “auto range” option
selected, the terrain display range is automatically set to 10nm
whenever a terrain or obstacle alert takes place, overriding the
current range selection. To remind you that the range has been
automatically changed, the text “Auto” is added in the range
annunciation. Manual range control is not disabled by auto-range.
You can reset the range to any desired value.
5.3.2 Simultaneous Alerts
If a terrain or obstacle alert and Traffic Advisory (TA) are issued at the
same time, TAWS will have priority, and the terrain or obstacle alert
message will be presented in the Message Bar. When you
acknowledges the alert, the EX5000 switches to the TAWS Display
page. After you acknowledge the TAWS message from the TAWS
page, the TA is shown in the Message Bar. If you then acknowledge
the TA, the dedicated Traffic page (discussed in Section 3.1, "The
Dedicated Traffic Page" on page 25) displays.
If a TA occurs while a terrain or obstacle alert is in progress and the
TAWS Display page is being displayed, the EX5000 will remain in
TAWS Display and the TA message will appear in the Message Bar.
Acknowledging the TA message displays the dedicated Traffic page.
5.3.3 Terrain Messages and Error Indications
The TAWS display may present messages in the Message Bar.
Press ACK button to acknowledge TAWS page messages and
remove them from the message bar. Large text annunciations will
remain. See Table 12.12 TAWS Messages on page 152 for a listing
of possible TAWS messages.
If the TAWS page is accessed immediately after you turn on the
EGPWS, the system may still be initializing and the TAWS page will
display the text “TAWS Initializing” rather than the expected terrain.
The EGPWS and TAWS page will begin normal operation when
initialization is complete.
