KAP 140 Two Axis Operation
The KAP 140 is a digital, panel-mounted autopilot system for light air-
craft.
1. PITCH AXIS, (P) ANNUNCIATOR
- When illuminated, indicates failure
of the pitch axis and will disengage
the autopilot when the failure occurs
and not allow engagement of the
pitch axis.
2. AUTOPILOT ENGAGE/DISEN-
GAGE (AP) BUTTON - When
pushed, engages autopilot if all logic
conditions are met. The autopilot
will engage in the basic roll (ROL)
mode which functions as a wing lev-
eler and in the vertical speed (VS)
hold mode. The commanded verti-
cal speed will be displayed in the
upper right corner of autopilot dis-
play area. The captured VS will be
the vertical speed present at the
moment of AP button press. When
pressed again, will disengage the
autopilot. For software version 03/01

TOR BUTTON - When pushed, will
arm the Heading mode, which com-
mands the airplane to turn to and
maintain the heading selected by the

selected at any time and will result in
the airplane turning to the new head-
ing. Button can also be used to tog-
gle between HDG and ROL modes.
