Three envelopes are defined for Air Transport aircraft. These
are identified as Basic Bank Angle, Bank Angle Option 1, and
Bank Angle Option 2 advisories.
The Air Transport Basic Bank Angle limits are similar to the
Business Aircraft Bank Angle limits except above 150 feet the
bank limit remains at 40 as shown below.
Bank Angle Option 1 provides bank angle advisory thresholds
at 35, 40, and 45 independent of altitude. In this case, an
advisory at 35 is provided and another is not given unless 40
is exceeded and then again only if 45 is exceeded. If the roll
rate exceeds the audio callout time, then the bypassed limit is
Also, when any one of the thresholds is exceeded, the bank
angle must reduce below 30 for the process to reset before
additional Bank Angle Advisories can be provided.
For example, if greater than 40 is obtained before the 35
callout is complete, another callout is provided only if 45 is
obtained or the bank angle is reduced to less than 30 and then
again increases to 35.
Bank Angle Option 2 provides a combination of the Basic
Bank Angle and Bank angle Option 1. The Basic Bank Angle
limits are provided below 130 feet, and Bank Angle Option 1
is provided above 130 feet.
Any one of these three Bank Angle limits can be selected by
program pin if the aircraft type is defined as an Air Transport
