intercept course in NAV mode or twice to intercept course in
GPSS mode on the autopilot programmer/computer. When
the on-course intercept turn begins the HDG mode will
disengage and the annunciator will go out.
During the intercept sequence, the autopilot operates at
maximum gain and sensitivity (90% of standard rate turn).
When the selected course is intercepted, course deviation
needle centered, the course-tracking program is activated.
The system
approximately 15 seconds while the wind correction angle is
established. The maximum turn rate is then reduced to 45%
standard rate. Approximately 60 seconds later, the maximum
turn rate is reduced to 15% standard rate.
4. For increased sensitivity during GPS approach or if desired for
enroute tracking, press the APR button on the autopilot
programmer/computer. The NAV, GPSS, and APR annunciators
will be illuminated. Use HDG to accomplish a procedure turn.
Engage GPSS again to complete the approach.
VOR Tracking and VOR-LOC Approach
1. Begin with a reliable VOR or VOR-LOC signal selected on the
NAV receiver.
2. Select desired course on HSI and establish a desired intercept
heading.
3. Press the NAV button on the autopilot programmer/computer. The
NAV mode will illuminate. Course interception and tracking will be
as described under GPS Tracking and GPS Approach above.
4. For station passage, set HDG bug to within 5° of selected course.
If the HDG bug is within 5° of center and the course deviation
is less than 10%, the autopilot will immediately establish the
lowest level of sensitivity and limit the turn rate to a maximum
of 15% of a standard rate turn.
5. For increased sensitivity during approach or if desired for enroute
tracking, press the APR button on the autopilot programmer/
computer. Both NAV and APR annunciators will be illuminated.
