NOTE
•
When operating at or near the best rate-of-climb
airspeed, with the engine set to climb power or when in
vertical speed mode, it can be easy to slow to airspeeds
where any additional reduction in airspeed will result
reduced rate-of-climb. Hold sufficient airspeed during
vertical speed mode operation to avoid a stall.
c. AP Button - PUSH and HOLD to engage the autopilot. Make
sure that ROL and VS are shown on the face of the
autopilot. If no selection of other operating modes is made,
the autopilot will operate in ROL and VS modes.
NOTE
When operating in ROL mode, turbulence may result in
changes to airplane heading. ROL mode only works to
keep the wings level. When tracking the ILS course
outbound on the missed approach procedure, use NAV
mode to prevent unwanted GS coupling.
BEFORE LANDING
1. A/P DISC/TRIM INT Switch - PUSH to disengage the autopilot.
PERFORMANCE
There is no change in airplane performance when the Bendix/King KAP
140 2 Axis Autopilot is installed. Refer to the Operating Limitations
section of this supplement for limitations that can have an effect on
airplane performance.
