10.8.5.6 Inhibiting/Enabling TAWS-A PDA/FLTA Alerting
TAWS-A also has an inhibit mode that deactivates the PDA/FLTA aural and
visual alerts. Pilots should use discretion when inhibiting TAWS-A and always
remember to enable the system when appropriate. Only the PDA and FLTA
alerts are disabled in the inhibit mode. After cycling power, TAWS-A will no
longer be inhibited.

1. While viewing the Terrain page, touch the
Menu
key.
2. Touch the
TAWS Inhibit
key to inhibit or enable TAWS (choice
is dependent on current state). A green bar in the key indicates
the TAWS is inhibited.
10.8.5.7 Excessive Closure Rate Alert
The
Excessive Closure Rate (ECR)
alert provides suitable notification
when the aircraft is determined to be closing upon terrain at an excessive speed
for a given aircraft gear and flap configuration.
The following figures show the ECR alerting criteria for flaps in the landing
configuration and for all other flight phases respectively.
ECR alerts are automatically inhibited when the aircraft is 5 NM from the
nearest airport, except when FLTA is not available (causing the TAWS N/A or
TAWS FAIL annunciation to be displayed), in which case ECR alerting will
remain active until landing.
