Why is the autopilot always on?

The autopilot controls the dampening system that prevents pilot-induced oscillation. The autopilot master switch should therefore always be on unless there is an autopilot malfunction. Altitude and attitude hold functions are then engaged/disengaged as needed with the pushbutton switches on the autopilot panel. If you switch off the autopilot you will get a general warning indication. In the real Draken the master switch was wire-sealed in the on position.

Switching between Draken and another airplane in flight is not recommended as this could screw up the autopilot settings.
