BENDIX/KING KAP 1402 AXIS AUTOPILOT
GENERAL
The Bendix/King KAP 140 2-Axis Autopilot provides the following
modes of operation:
1. Roll (ROL) mode - keeps the wings level,
2. Vertical Speed (VS) mode - holds the climb or descent rate
at the moment the autopilot is engaged or a manually-set
climb or descent rate. Controlled using the UP and DN
buttons.
NOTE
The autopilot can hold a set vertical speed only if
engine power and airplane weight will let it. If the
vertical speed set on the autopilot is more than the
airplane can supply and airspeed decreases
sufficiently, the airplane can be made to stall. Make
sure that the vertical speed set on the autopilot
results in airplane performance that stays in the
operating limitations of both the autopilot and the
airplane.
3. Altitude Hold (ALT) mode - holds a set altitude using
combined engine power, pitch and pitch trim control.
4. Heading (HDG) mode - holds the magnetic heading set
using the HDG bug on the G1000 Primary Flight Display
(PFD) HSI.
5. Navigation (NAV) mode - locks on a course set using the
CRS knob when a valid VHF navigation source (NAV 1 or
NAV 2) is shown on the G1000 HSI, when GPS is set as the
HSI navigation source and the GPS is operating in OBS
mode, or when the course is set automatically using GPS
direct-to or flight plan (FPL) navigation and GPS is shown
on the G1000 HSI.
