FLTA alerts are automatically inhibited 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.
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 (Figure 6-60).
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.
