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 will remain at maximum sensitivity for
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.
• Note •
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.
