Additional Taws-B Alerting - Garmin G1000 NXi Pilot's Manual

The system automatically disables FLTA alerts when the aircraft is less than 200 feet above the destination
runway elevation while within 0.5 nm of the approach runway or the aircraft is between runway ends.
When Terrain-SVT or TAWS-B FLTA alerts are manually inhibited, the annunciation is shown on the PFD and
in the MFD for maps displaying relative terrain

ADDITIONAL TAWS-B ALERTING

In addition to the FLTA alerting discussed previously, TAWS-B provides the following additional types of
alerts.
PREMATURE DESCENT ALERTING
A Premature Descent Alert (PDA) is issued when the system detects that the aircraft is significantly
below the normal approach path to a runway.
PDA alerting begins when the aircraft is below 700 feet AGL within 15 nm of the destination airport and
ends when the aircraft is 0.5 nm from the runway threshold.
