This chapter contains instructions for checking out an ATD installation. Checks shall ensure
the system is properly installed and functioning correctly.
5.1 Wiring Checks
Verify that all cables are properly secured. Check the movement of aircraft controls to verify
there is no interference between the cabling and controls. Ensure that all wiring is installed
as described.
Prior to powering up ATD, the wiring harness must be checked for proper connections
to the aircraft systems and other avionics equipment. Point to point continuity must be
checked to expose any faults such as shorting to ground.
After accomplishing a continuity check, perform power and ground checks to verify proper
power and GND levels are present. Any faults or discrepancies should be corrected at this
time.
Any faults or discrepancies must be corrected before proceeding.
Make sure shielding is installed where appropriate.
ATD may be connected after completion of the continuity and power checks. All connections
must be made before the unit is powered up.
5.2 Connector Engagement Checks
Prior to powering up ATD, a connector engagement check should be performed.
1. Optically inspect all interconnects.
2. Check if all connectors are locked properly, verify by gently pulling on the connectors.
