1. PITCH AXIS (P) ANNUNCIATOR - P annunciations on the lower
left corner of the KAP 140 autopilot computer indicates failure of
pitch axis and will either disengage the autopilot or not allow
engagement of the pitch axis. In turbulent air, the P annunciator
may illuminate during abnormal vertical accelerations.
2. AUTOPILOT ENGAGE/DISENGAGE (AP) BUTTON - When the
AP button is pressed and held for approximately 0.25 seconds,
the autopilot will engage only if all preflight self-test conditions
are met. The autopilot will engage in the basic roll (ROL) mode
which functions as a wing leveler and the pitch axis vertical
speed (VS) mode. The commanded vertical speed will be
displayed in the upper right corner of the KAP 140 autopilot
computer display. The captured VS will be the vertical speed
present at the moment the AP button is pressed. The AP button
may also be used to disengage the autopilot.
3. ROLL AXIS (R) ANNUNCIATOR - R annunciations on the lower
left corner of the KAP 140 autopilot computer indicates failure of
the roll axis and will disengage the autopilot or not allow
engagement of the roll axis.
