MFD Terrain Awareness Display
Do not use the Terrain Awareness Display for navigation of the
aircraft. The TAWS is intended to serve as a situational
awareness tool only and may not provide the accuracy fidelity
on which to solely base terrain or obstacle avoidance
To select the Terrain Awareness Display Page on the MFD, rotate the
page knob to TAWS.
Terrain and obstacle alerts are the most critical situations displayed by
TAWS. There are two levels of alerts:
• Caution Alert - Possible terrain or obstacle conflict within 40-
60 seconds. When triggered, the terrain or obstacle that
caused the alert is displayed in bright yellow. In addition, a
message describing the nature of the alert is presented in the
MFD message bar.
• Warning Alert - Possible terrain or obstacle conflict within 30
seconds. When triggered, the terrain or obstacle that caused
the alert is displayed in bright red. In addition, a message
describing the nature of the alert is presented in the message
When a caution or warning alert is active, the display image
surrounding the target is enlarged somewhat to allow the terrain or
obstacle to be better seen on the display.
If a terrain or obstacle alert occurs while a page other than Terrain
Awareness Display Page is being displayed, a terrain or obstacle alert
message is displayed in the Message Bar. When the pilot
acknowledges this message, the MFD will automatically switch to the
Terrain Awareness Display Page.
The message bar will be removed from the display when the TAWS is
no longer in alert status, or if the pilot acknowledges the message from
the Terrain Awareness Display Page.
