The default roll axis mode is Roll Hold (ROL). When
no other roll axis modes are selected, this is the active
roll axis mode when the autopilot and/or flight director
is engaged.
Roll Hold Mode (ROL)
1) Press the
FD
or
AP
Key.
If the aircraft bank angle is
≥ 6 degrees when
the key is pressed, Roll Hold Mode is selected by
default. Roll attitude at the time of activation
is maintained by the autopilot up to 25˚. If
only the flight director is active, command bars
indicate the proper roll attitude.
If the aircraft bank angle is < 6 degrees
when the key is pressed, the aircraft will be
maintained at wings level. If only the flight
director is active, command bars give guidance
to maintain wings level.
Roll Hold Mode is annunciated by ‘ROL’.

2) A new heading can be established by pressing
and holding the
CWS
Button and manually
turning the aircraft to the desired new heading.
Release the
CWS
Button and the aircraft will
maintain wings level at approximately the new
heading, but will not hold the heading. The
same practice applies to holding roll attitude.
