Roll Hold Mode (Rol); Low Bank Mode - Garmin Socata TBM850 Pilot's Manual

ROLL HOLD MODE (ROL)

If Roll Hold Mode is activated as a result of a mode reversion, the flight director rolls wings level.
NOTE:
When the flight director is activated or switched, Roll Hold Mode is selected by default. This mode is
annunciated as 'ROL' in the AFCS Status Box. The current aircraft bank angle is held, subject to the bank angle
condition.

CHANGING THE ROLL REFERENCE
The roll reference can be changed by pressing the CWS Button, establishing the desired bank angle, then
releasing the CWS Button.

LOW BANK MODE

When in Low Bank Mode, the flight director limits the maximum commanded roll angle to 15 ° . Low bank
arc limits are displayed in green along the Roll Scale.
Low Bank Mode can be manually selected/deselected by pressing the BANK Key while in Heading Select
or Navigation Modes (GPS and VOR). Low Bank Mode is activated automatically climbing above 25,000 ft
(FL250), and deactivated when descending below 25,000 ft. The annunciator light next to the BANK Key
illuminates while Low Bank Mode is selected.
