7.3 Servo Calibration Procedure
The SkyView HDX Autopilot servo settings are available for download as a configuration file that
is loaded into the SkyView HDX display. This file configures the autopilot servo performance
settings to meet the applicable certification regulations. Servo calibration cannot be performed
without the following:
• An ADAHRS module (SV-ADAHRS-200) installed and configured in the SkyView
network.
• All servos installed and configured in the SkyView network.
• V-speeds correctly entered in SkyView HDX. (See the 103261-000 SkyView HDX
System Installation Manual document for instructions.)
To make a new servo appear on the SkyView HDX display, configure the SkyView network
(SYSTEM SETUP > NETWORK SETUP > CONFIGURE). (See the 103261-000 SkyView HDX
System Installation Manual document for instructions.)
To calibrate the servos, enter the Servo Calibration Wizard (SETUP MENU > HARDWARE
CALIBRATION > AP SERVO CALIBRATION > CALIBRATION) and follow the onscreen
instructions to calibrate the servo(s).
SkyView HDX checks the status of the AP Disengage Button. If SkyView HDX detects that the
button is pressed (the input is grounded) upon entering AP SERVO CALIBRATION, the AP
Disengage Button is assumed to be stuck (or incorrectly installed), resulting in the following
message being displayed, and the Autopilot servo calibration is aborted:
"The servo disconnect switch appears to be pressed and may be installed
incorrectly. The servo disconnect switch should be a type Momentary, Push Button
Normal Open (PBNO). Press cancel below to return to the servo calibration menu."
If the servo calibration procedure is not successful, inspect the button and servo wiring. (See the
103261-000 SkyView HDX System Installation Manual document for instructions.) If button type
and wiring is correct, call Dynon Technical Support.
If the servo calibration procedure is successful, SkyView HDX will automatically instruct you to
run the servo test procedure. (See Section 7.4 for instructions.)
