A simple remedy for this problem if it occurs is a tee-fitting near the static port, and a dedicated line to
the autopilot only. Obviously, an insufficiently-large orifice coupled with large static reservoirs can
aggravate the problems associated with lag.

RFI/EMI Considerations
The autopilot controller is shielded and does not generate any appreciable level of electromagnetic
interference. Moreover, the servo lines (except for power and ground) are low-current and cannot
contribute to RF interference. The servo power and ground lines do have switching currents through
them, but so long as there are no parallel runs of servo power and ground lines with such things as
poorly-shielded antenna lines or strobe light power lines, there is no need to shield the servo harnesses.
The autopilot itself has been internally protected from RF interference and has been tested under fairly
extreme conditions, such as close proximity to transmitting antennas. However, it is always good
practice to ensure that such antennas are properly shielded and not routed directly over or under
sensitive panel-mounted electronic equipment. Most problems in this area are the result of improper RF
shielding on transmitting antennas, microphone cables, and the like. The most sensitive input to the
autopilot is the Control Wheel Switch input. This line should not be routed in parallel with transmitting
antennas or other sources of known RF interference. If necessary, it can be shielded with the shield
connection to pin 13 of the autopilot connector.

GROUND CHECKOUT
Once installation and setup of the autopilot are complete (see Operation Manual for setup and
operation instructions), a ground checkout is a good idea before the first flight of the system. This is a
simple procedure to verify that the servos move in the correct direction. Follow the steps below to
verify this:
-1) Center both the aileron and elevator control surfaces.
-2) Engage the autopilot.
-3) Rotate the knob clockwise, make sure the controls move to the right (stick) or clockwise (yoke).
-4) Rotate the knob counter-clockwise. It must be turned enough to select a left bank angle. Make sure
the controls move to the left (stick) or counter-clockwise (yoke).
-5) Toggle the joystick up to select a 500 fpm climb. Make sure the controls move aft.
-6) Toggle the joystick down to select a 500 fpm descent. Make sure the controls move forward.
If steps 2-6 are all verified then the xCruze 110 AP is ready to be engaged in flight.
