Operation
All interface with TAWS is conducted through the FMS, the weather radar control panel, the
EFIS control panel and ND.
The FMS can display TAWS pages allowing the operator the ability to change TAWS
displays and operation settings.
The TAWS pages provides four pages on which the following can be displayed:
• View perspective.
• Vertical and horizontal range.
• The number of waypoints.
• TAWS displays and Self-Test.
• TAWS software.
•
Terrain and airport databases.
Cold temperature correction
TAWS is corrected for co
ld temperatures.
Barometric altimeter
CAUTION:
• TAWS relies on accurate barometric altitude data for proper operation.
• Correction of altimeter settings for the area of operation is required.
Emergency procedures
In the event that the Airplane Flight Manual requires a flap setting not normally required for
landing, press the FLAP OVRD push button to simulate flaps in landing position.
When an off airport landing or ditching is required the Forward-Looking Terrain-Avoidance
(FLTA) and Premature Descent Alert (PDA) functions should be inhibited by activation of the
TERRAIN INHIBIT switch.
The GPWS circuit breaker may be pulled to deactivate the TAWS when an emergency
procedure in the emergency checklist specifies landing with the gear up.
