6. Press NAV button again and the autopilot will return
to the ROL mode.
Note: it is important to understand that in installations
with a DG the Heading Bug is supplying the OBS signal
to the autopilot. The CDI does not output the necessary
signal strength for where the OBS card is set.
Therefore, Heading Bug must correspond with desired
VOR/LOC/GPS track. When following a GPS flight
plan, the Heading Bug must be repositioned to the next
waypoint course as soon as it is captured and the
aircraft begins the turn towards the new track.
In the approach (APR) mode, the autopilot intercepts
and tracks VOR/LOC/ILS and GPS courses.
To arm APR mode (with the KAP 140 currently in the
HDG mode):
1. Select the desired frequency for VOR or LOC/ILS.
For GPS, verify the desired waypoint or destination.
2. OBS Knob - SELECT desired course. (For a
localizer, set it to serve as a memory aid.)
3. APR Mode Selector Button - PRESS. Note APR

The autopilot will flash HDG for 5 seconds to remind
the pilot to reset the HDG bug to the OBS course.
