10.8.5.11 Inhibiting GPWS Alerts (EDR, ECR, FIT, and NCR)
NOTE: The "Inhibit GPWS" function only affects GPWS alerts (EDR, ECR, NCR,
and FIT). Alerting for FLTA, PDA, and GSD is controlled independently from the
GPWS alerts listed below.
EDR, ECR, FIT, and NCR aural and visual alerts can be manually inhibited as
a group. Discretion should be used when inhibiting alerts and the GPWS system
should be enabled when appropriate. When these alerts are inhibited, the alert
annunciation “GPWS INH” is shown on the TAWS-A Page annunciation window.
1. While viewing the TAWS-A Page, touch the
MENU
key.
2.
Touch the
GPWS INH
key to inhibit or enable GPWS alerts
(choice dependent on current state).

10.8.6 Altitude Voice Call Out (VCO)
TAWS-A provides aural advisory alerts as the aircraft descends, beginning at
500 feet above the terrain, as determined by the radar altimeter (if greater than
5 NM from the nearest airport) or 500 feet above the nearest runway threshold
elevation (if less than 5 NM from the nearest airport). Upon descent to this
altitude, TAWS-A issues the aural alert message
“
Five-hundred.
