Autopilot Servo Installation, Configuration, and Calibration
SkyView System Installation Guide - Revision K 10-25
You should be able to find a sensitivity level that is acceptable for both heading
holds and turns in smooth air. You may, however, find that in periods of extended
turbulence, a lower sensitivity level must be set.
Verify turn rate limit and bank limit settings during turn(s)
During an autopilot-controlled turn, verify that the time to complete a turn matches your
expectations given the setting for the turn rate target. For example, if the turn rate target is set
to 3 degrees per second, a 90 degree turn should take about 30 seconds. If this is not the case,
the bank angle required by the target turn rate may exceed the set maximum bank angle.
Ensure that during an autopilot-controlled turn, the bank angle indicated on the PFD does not
reach your maximum bank angle. If it does, you must either increase the maximum bank angle
or decrease the turn rate target.
At this point, all the parameters in the Roll Axis Menu should be appropriately tuned.
Disengage the autopilot
Disengage the autopilot by either pressing and holding the disengage button for 2 seconds or
by entering the AP Menu (MAIN MENU > AP MENU) and toggling both axes to off ( i.e.,
and ).
Pitch Servo Flight Tuning Procedure
This procedure tunes the pitch autopilot servo and thus, the flight characteristics of the aircraft
in altitude holds, climbs, and descents.
Pitch Servo Flight Tuning Procedure Overview
The following list is an overview of the pitch servo flight tuning procedure. Each step is
described in more detail after the list.
1. Verify preferred airspeed minimum and maximum values and default climb and descent
vertical speeds.
2. Ensure the aircraft is in trim.
3. Engage the autopilot in altitude mode.
4. Allow a few minutes of stable flight under autopilot control.
5. Adjust roll servo torque and/or sensitivity and/or pitch gain values as needed.
6. Initiate autopilot-controlled climbs and descents.
7. Verify roll torque, sensitivity, and the other available advanced gain and rate settings
during climbs and descents.
8. Verify airspeed minimum and maximum values and default climb and descent vertical
speeds during altitude changes.
9. Execute several autopilot-controlled changes of altitude and observe the overall aircraft
performance.
10. Observe and verify trim indications during altitude holds and changes.
