Navigation Mode From Rol Mode - Honeywell KAP 140 Installation Manual

Navigation (NAV) Mode from ROL Mode (All Angle Intercept)
In the navigation (NAV) mode, the autopilot intercepts
and tracks VOR/RNAV and GPS courses.
To arm NAV mode (with the KAP 140 currently in the
ROL mode):
Maneuver the aircraft to the desired intercept angle
prior to selecting ROL mode.
1. Select the desired frequency for VOR or RNAV. For
GPS, verify the desired waypoint or destination.
2. OBS Knob - SELECT desired course.
3. NAV Mode Selector Button - PRESS. Note NAV
ARM annunciated
.
The autopilot will flash HDG for 5 seconds to remind
the pilot to reset the HDG bug to the OBS course.
Check the heading displayed on the DG against the
magnetic compass and reset if necessary.
4. Heading Selector Knob - ROTATE BUG to agree
with OBS course.
If CDI needle is to the left, desired intercept course
should be 30º or greater to the left of selected (Heading
Bug) course; and 30º or greater to the right is CDI
needle is to the right. Intercept angles greater than 45°
can result in course overshoot when close to the VOR
station or LOC/GPS signal. Therefore, intercept angles
greater than 45° are not recommended.
