change to recapture the altitude when the control input is
released.
3. Altitude can be synchronized to another altitude by rotating the VS
knob on the programmer/computer. Clockwise rotation will
increase and counterclockwise rotation will decrease altitude 20
feet for each ‘click.’ The maximum adjustment is ±360 feet.
Adjustments greater than 360 feet can be made by selecting VS
mode and flying the airplane to the new altitude and then reengaging
ALT mode.
Vertical Speed Mode
1. Begin by manually establishing the desired vertical speed.
2. Press HDG or NAV to engage a roll mode. The associated
annunciator will illuminate.
• Note •
A roll mode must be engaged prior to engaging a pitch mode.
3. Press the VS button on the autopilot programmer/computer to
engage the vertical speed mode. When the mode is engaged, the

autopilot will synchronize to and hold the vertical speed at the time
the mode was engaged.
• Note •
The vertical speed is displayed in 100-foot increments on the
programmer/computer window. A plus (+) value indicates
climb and a negative or minus (-) value indicates descent.
4. Vertical speed can be adjusted by rotating the VS knob on the
programmer/computer or the right knob on the PFD when the VSI
bug has been selected.
• Note •
A flashing VS mode annunciator indicates excessive error
between actual vertical speed and the selected vertical speed
(usually in climb). The pilot should adjust power or reduce the
commanded vertical speed as appropriate to remove the
error.
GPS Tracking and GPS Approach
1. Begin with a reliable GPS 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.
• Note •
If the course needle is at full-scale deviation, the autopilot will
establish the airplane on a heading for a 45° intercept with the
selected course. As the airplane approaches the course, the
autopilot will smoothly shallow the intercept angle. The pilot
may select an intercept angle less than the standard 45° by
setting the desired intercept heading with the HSI HDG bug,
pressing and holding HDG, and then pressing NAV once to
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 approach or if desired for enroute
tracking, press the APR button on the autopilot programmer/
computer. Both NAV and APR annunciators will be illuminated.
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.
