The callout "BANK ANGLE, BANK ANGLE" advises of
an excessive roll angle. The EGPWS provides several
excessive bank angle envelopes supporting Air Transport,
Business, or Military aircraft types (only Air Transport and
Business aircraft types are addressed below).
One envelope is defined for turbo-prop and business jet
aircraft (see graph below). Bank angles in excess of:
• ±10° between 5 and 30 feet,
• ±10 to 40° between 30 and 150 feet,
• ±40 to 55° between 150 and 2450 feet,
• 55° above 2450 feet
produce the bank angle advisory (shaded area). Bank angle
advisories are inhibited below 5 feet.
