Autopilot Servo Installation, Configuration, and Calibration
10-12 SkyView System Installation Guide - Revision K
While not required, you may install a 4.7 - 5.3k ohm resistor across the AP Disengage/CWS
button. A future firmware update will allow SkyView to detect a break in this circuitry if this
resistor is present in the installation.
Wire Sizing
While it is beyond the scope of this installation guide to advise on specific types of wiring for a
particular aircraft, choice of wiring should be sized to 1) minimize voltage drop over the length
of the particular wiring run, and 2) conduct the amount of current required by the subsystem
without the wiring becoming warm to the touch. Appendix C: Wiring and Electrical Connections
contains information and suggested resources for wiring and electrical connections.
Wiring Installation
Care should be taken such that aircraft wiring is not subjected to chafing, excessive flexing, or
connections/junctions subjected to excessive vibration which may cause the
connection/junction to fail or short-circuit.
Autopilot Servo Calibration and Test Procedures
You must calibrate, test, fine tune, and flight test the autopilot servos in order to
complete the autopilot installation.
Adjusting autopilot settings while the autopilot is engaged is not recommended, as
some settings changes may cause the autopilot to react immediately and counter
to the pilot’s immediate expectations.
All servos must be properly networked into the SkyView system and IAS tape colors /
v-speeds must be configured prior to any servo calibration, testing, or tuning.
Reference the Network Setup and Status Section for instructions on how to
network the servos into the system and the Airspeed Limitations Section for
instructions on how to set IAS tape colors.
Servo Calibration Procedure
The servo calibration procedure identifies the orientation and range of motion of each servo
and must be performed before the servo test procedure. SkyView uses this procedure to
automatically differentiate between the pitch and the roll servos.
To calibrate the servos, enter the Servo Calibration Wizard (SETUP MENU > HARDWARE
CALIBRATION > SERVO CALIBRATION > CALIBRATION) and follow the onscreen instructions to
calibrate the servo(s). If the servo calibration procedure is successful, SkyView will automatically
instruct you to run the servo test procedure.
