3.2.5 TAWS CAUTION (Terrain or Obstacle Ahead, Sink Rate, Don't

Sink)

When a TAWS CAUTION occurs, take corrective action until the alert ceases.

Stop descending or initiate either a climb or a turn, or both as necessary, based

on analysis of all available instruments and information.

TAWS annunciators external to the GTN may not indicate the

exact threat causing the alert. Example: WIRE alerts may be

annunciated as TERR or OBSTACLE on external devices.

3.2.6 TAWS INHIBIT

The TAWS Forward Looking Terrain Avoidance (FLTA) and Premature

Descent Alerts (PDA) functions may be inhibited to prevent alerting, if desired.
