Inhibiting Glideslope Deviation (GSD) Alerts
NOTE
: The G/S Inhibit function should be activated when flying a localizer
backcourse approach to prevents nuisance GSD alerts. GSD alerts are
inhibited independent from all other FLTA, PDA, and GPWS alerts.
1. While viewing the TAWS-A Page, touch the
MENU
key.
2.
Touch the
G/S Inhibit
key to inhibit or enable glideslope or
glidepath alerts (choice dependent on current state).
NOTE
: The G/S Inhibit function will only be active for a single approach
and the inhibit function will not remain active for subsequent approaches.
When G/S alerts are inhibited, they are only inhibited for a single approach.
To inhibit G/S alerts on the next approach, the G/S Inhibit function must
be activated again between the first and second approaches.
NOTE
: Glidslope Deviation alerts will not be available if the G/S INHB
function is activated.
