KAP 140 Two Axis with Altitude Preselect 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 leveler
and in the vertical speed (VS) hold
mode. The commanded vertical
speed is be displayed in the upper
right corner of autopilot display area
for three seconds after engagement
or if either the UP or DN button is
pressed. 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
and later, the AP button must be
pressed and held for 0.25 seconds
to engage the autopilot.
3. ROLL AXIS (R) ANNUNCIATOR
- When illuminated, indicates failure
of the roll axis and will disengage the
autopilot and not allow engagement.
4. HEADING (HDG) MODE SELEC-
TOR BUTTON - When pushed, will
arm the Heading mode, which com-
mands the airplane to turn to and
maintain the heading selected by the
heading bug on either the DG or
HSI. A new heading may be
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.
This button will engage the autopilot
in units with software prior to soft-
ware version 03/01.
