TAWS Operation

Inhibit Mode

TAWS provides an ‘inhibit mode’ (Figure 2-4). This mode is designed to deactivate PDA/FLTA aural

and visual alerts when they are deemed unnecessary by the aircrew. Flying VFR into an area where unique

terrain exists could cause the system to annunciate a nuisance alert. Pilots should use discretion when

inhibiting the TAWS system and always remember to enable the system when appropriate. Only the PDA

and FLTA alerts are disabled in the inhibit mode. See section 3 for more information on TAWS alerts.

To inhibit TAWS:

1. Select the TAWS Page and press MENU. ‘Inhibit Terrain?’ is selected by default.

2. Press

ENT. The TAWS system is inhibited. The annunciation is displayed in the terrain

annunciator ﬁeld whenever terrain is inhibited (Figure 2-4).

To enable TAWS:

1. Select the TAWS Page and press MENU. ‘Enable Terrain?’ is selected by default.

2. Press

ENT. The TAWS system is functional again.
