BANK ANGLE CALLOUT
Minimum Terrain Clearance (MTC) for message triggering for GPWS:
− Minimum: 0 ft.
− Maximum: Increases linearly from 30 ft at 10° of bank angle to
150 ft at 40° then from 150 ft at 40° up to 2450 ft at 40°.
Minimum Terrain Clearance (MTC) for message triggering for
EGPWS:
− Minimum: 5 ft.
− Maximum: Increases linearly from 30 ft at 10° of bank angle to
150 ft at 40° then from 150 ft at 40° up to 2450 ft at 55° ,
remaining constant at 55° above 2450 ft.
The aural message "BANK ANGLE, BANK ANGLE" is sounded when
the airplane bank angle is too high or roll rate exceeds 1°/sec during
all phases of flight.
The message is generated again if bank angle increases by 20%.
For airplanes equipped with EGPWS, when roll attitude increases to
40% above the initial callout angle, the callout will repeat continuously.
