* No annunciation appears in the AFCS Status Box. The commandable bank angle range is indicated by
a green band along the Roll Scale of the Attitude Indicator.
** ESP equipped aircraft only. LVL mode is entered from an automatic engagement of the autopilot due
to the aircraft remaining outside of the normal flight envelope for approximately 10 seconds.
The CWS Button does not change lateral references for Heading Select, Navigation, Backcourse, or
Approach modes. The autopilot guides the aircraft back to the Selected Heading/Course upon release of
the CWS Button.
The autopilot may be engaged within the following ranges:
Pitch 50° nose up to 50° nose down
Roll ±75°
If the above pitch or roll limits are exceeded while the autopilot is engaged, the autopilot will disconnect.
Engaging the autopilot outside of its command limits, but within its engagement limits, will cause the
autopilot to return the aircraft within command limits. The autopilot is capable of commanding the aircraft
in the following ranges:
Pitch 20° nose up to 15° nose down
Roll ±25°, or ±30° while using a GPS lateral mode
The Flight Director is not designed to perform unusual attitude recoveries from attitudes outside the
following range:
Pitch 50° nose up to 50° nose down
Roll ±75°
