Autopilot Operation
EFIS-D100 Pilot’s User Guide 7-17
If CWS mode is engaged and during this time airspeed exceeds AIRSP MAX (SETUP > AP > PITCH SERVO)
releasing the AP Disengage/CWS Button will not re-engage the AP. The Autopilot can only be re-engaged
when airspeed is below AIRSP MAX.
Optional Preflight Checklist
If you desire an Autopilot preflight test, the following can be used as a baseline.
1. With the circuit breaker for the servos powered OFF, test the controls for proper operation of the control
surfaces. The controls should feel normal; the servos should add little resistance. The EFIS-D100 should display
an
alert regarding DSAB connectivity. Additionally, the AP Status display should show AP:ERR:ERR.
2. With circuit breaker for the servos powered ON, observe the EFIS. Verify that the AP Status indicator now
shows AP:OFF:OFF.
3. Repeat Step 1; the “feel” should be the same as with servo power OFF.
4. Enter the EFIS > SETUP > AP > SERVO TEST menu and follow on-screen instructions. This verifies proper
operation of the AP servos and AP Disengage/CWS button.
