Autopilot Servo Installation, Configuration, and Calibration
SkyView System Installation Guide – Revision S 10-15
1N914, available from Radio Shack (P/N 276-1122). With a diode installed for each
display, the External LEVEL Button will work correctly with any combination of displays
powered on and powered off.

Use a multi-pole pushbutton (momentary, normally open / push to close) for the
External LEVEL Button. With this option, run each display's connection to a different
pole on the pushbutton. With the multi-pole pushbutton installed, the External LEVEL
Button will work correctly with any combination of displays powered on and powered
off.
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. Generally,
20 AWG wire is a suitable gauge for the servo power / ground wires for lengths up to 20’ of
wire.
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
There are both ground-based setup and in-flight turning procedures that are
required to fully configure your autopilot installation. Initial servo setup /
calibration / test procedures are covered in this guide. In-flight procedures are
covered in the SkyView Autopilot In-Flight Tuning Guide.
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.
