SPZ--8000 Digital Integrated Flight Control System

REV 2
Modes of Operation

ROLL HOLD MODE
The autopilot recognizes the roll hold mode as being operational when:
D No lateral flight director mode is selected and,
D The aircraft’s bank angle is greater than 6, but less than 45 and,
D Touch control steering (TCS) was used to initiate the roll maneuver.
When these conditions are satisfied, the autopilot maintains the desired
bank angle, as shown in Figure 8--2. If TCS is released at bank angles
greater than 45, the autopilot rolls the aircraft to a 45 bank and
maintains that angle. While the TCS button is pushed, the TCS
message is displayed on the advisory display unit and replaces the AP
annunciator on the EADI.
