L-1011 Autoflight: Command Modes (22-10)

Once an autopilot lever has been placed in CMD or or command, it continues to act as if it were in control wheel steering until pitch or roll command modes are engaged.

Command modes are selected by pressing the switchlights along the top of the autopilot panels. Only one pitch mode and one roll mode can be selected at a time. Selection of a second pitch or roll mode will automatically disengage the first pitch or roll mode. Selection of a command mode will cause both autopilot computers to operate in that mode even though only one computer is engaged.

The switchlight for each mode will illuminate to show positive mode selection.
