Table 9.3.2 Roll Modes
Wings Level/Roll Hold Mode (ROL)
Whenever the Flight Director is activated in the ab-
sence of a specific roll mode (i.e., the FD key is pressed),
Roll Hold mode is active under the following conditions:
• If the aircraft bank angle is
greater than or equal to
6 degrees, Roll Hold mode is selected by default.
The Flight Director maintains the roll attitude of
the aircraft at the moment of selection.
• If the aircraft bank angle is less than 6 degrees,
Wings Level is selected by default, and the Flight
Director rolls the wings level.
Both modes are annunciated by ‘ROL’.

Changing the Roll Reference
The pilot can establish a new reference to hold by
pressing the
CWS button, establishing the desired bank
angle, then releasing the CWS button. The selection of
Wings Level or Roll Hold is the same as for mode engage-
ment.
