10.8.5.8.1 Overriding Flaps-based FIT alerting
1. While viewing the TAWS-A Page, touch the
MENU
key.
2. Touch the
Flap Override
key to toggle the override state.
When the Flaps Override option is enabled, the annunciation “FLAP O/R”
is annunciated on the TAWS-A Page. If GPWS alerts are also inhibited (which
include FIT), the “FLAP O/R” annunciation is not shown.
FIT alerts also occur during takeoff or go-around if the aircraft’s height
above ground level (as determined by the radar altimeter) is too close to rising
terrain. TAWS-A will issue the aural message
“Too Low - Terrain”
annunciations when conditions enter the caution alert area.
