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
ARM annunciated
.
The autopilot will flash HDG for 5 seconds to remind
the pilot to reset the HDG bug to the OBS (or desired
for a LOC) 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 desired approach course for a LOC, or OBS
course for a VOR/GPS.
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.
5. If the Course Deviation Bar is greater than 2 to 3
dots the autopilot will annunciate APR ARM; when the
computed
capture
point
is
reached
the
ARM
annunciator will go out and the selected course will be
automatically captured and tracked. If the D-Bar is less
than 2 to 3 dots: the ROL mode will disengage upon
selecting APR mode; the APR annunciator will
illuminate
and
the
capture/track
sequence
will
automatically begin.
