Mode Selection
Heading Mode
1. Set the PFD Heading Bug to the desired heading on the compass
card.
2. Press HDG on Programmer/Computer. The HDG annunciation will
illuminate and the airplane will turn to the selected heading.
3. Use the PFD Heading Bug to make heading changes as desired.
Navigation Mode
1. Select a reliable VOR or VOR-LOC signal on the NAV receiver.
2. Set the PFD Course Pointer to the desired course on the compass
card.
3. Press NAV on Programmer/Computer. The HDG annunciation will
illuminate and the airplane will turn to the selected navigational
aid.
If the course needle is at full-scale deflection or if the aircraft's
closure rate to the selected course is sufficiently slow, the autopilot
will establish the airplane on a heading for a 45° intercept with the
selected course. Otherwise, the intercept angle will be less than
45°. As the airplane approaches the course, the autopilot will
smoothly shallow the intercept angle.
To manually select an intercept angle other than 45°:
a. Set the PFD Heading Bug to the desired course, such that the
difference between this heading and the desired course is the
intercept angle.
b. Set the PFD Course Pointer to the desired course.
c. Press and hold HDG and simultaneously press NAV once on
the Programmer/Computer. HDG and NAV annunciations will
illuminate and the airplane will turn to the selected heading.
d. When the on-course intercept turn begins the HDG mode will
disengage and the annunciation will go out.
