10.2 TAWS INH
FLTA and GPWS alerting, can be inhibited by pressing the TAWS
NORM/TAWS INH softkey on the Pilot’s Menu. This feature can also be
operated by holding the external mounted MUTE button for 2 seconds, if
installed. When active this function removes terrain from the screen.
This feature is used for:
Abnormal failure of GPS/FMS resulting in erroneous data. A
conventional (flagged) GPS/FMS failure will automatically fail
alerts and the terrain display.
To eliminate nuisance alerts during unusual VFR missions.
A perceived nuisance alert should be brought to the attention of
Sandel Avionics for analysis.
Be aware that the TAWS INH function cancels all FLTA alerts and inhibits
GPWS modes 1, 3, 4, and 5. When TAWS INH is active, Altitude
Callouts remain active.
