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.
