Autopilot Installation and Configuration
6-16 EFIS-D10A Installation Guide
2 SERVO(S) FOUND PLEASE CENTER ALL CONTROL SURFACES AND MAKE SURE
THEY HAVE A FREE RANGE OF MOTION. PRESS DISCONNECT SWITCH TO
CONTINUE.
 Follow all onscreen instructions, moving the controls to each position, pressing the
Disengage/CWS Button to confirm each position. This process calibrates the autopilot to
detect the orientation and range of each servo.
 If calibration was successful:
CALIBRATION WAS SUCCESSFUL. ROLL FOUND. PITCH FOUND. PRESS OK BELOW
OR PRESS DISCONNECT SWITCH TO CONTINUE.
 Press the AP Disengage/CWS Button or OK button on the EFIS.
 If calibration was unsuccessful, an error message is displayed, describing the reason. The
most common causes are not enough travel being detected, or too much travel. In either
case, mechanical adjustments must be made.
After successful completion of the calibration, the system automatically continues into SERVO
TEST Mode. An initial SERVO TEST must be performed before the autopilot is usable. If the
initial SERVO TEST is canceled, the AP status display at the lower left of the EFIS screen
shows “TST” as the status for the installed servo(s).
 After successful calibration the screen displays:
PLEASE CENTER ALL CONTROL SURFACES AND MAKE SURE THEY HAVE A FREE
RANGE OF MOTION. PRESS OK BELOW TO BEGIN THE TEST.
 Follow all onscreen instructions, moving the controls to each position, pressing the OK
button to confirm each position. This process verifies that the controls move to the
correct position, and ensures that the Disengage/CWS Button properly disengages the
servos.
Note: After successful completion of Configure DSAB, Servo Calibration, and Servo Test, the
AP mode is enabled. The following occurs:
 The AP status indicator is displayed at
the lower left of the EFIS screen
(shown at right).
 The AP button is present on the EFIS
menu, replacing the BUGS menu
(which is now located within the AP menu).
 All bugs (IAS, Heading, and Altitude) are turned hollow.
With an autopilot installed, the heading and altitude bugs
are only filled in when those modes are engaged (HDG,
TRK, ALT hold).
 The EFIS now has a record of which servo performs which function and the particular
range of motion it will be executing.
If servos are swapped or replaced, Servo Calibration must be performed again.
