1.4 Service Philosophy

The first objective is to determine if the installed autopilot system is functioning properly on the ground. This is

accomplished by performing the functional ground test for that particular system. No external test equipment is

required.

The second objective is to isolate a failure to a system component. The equipment listed in section 1.3 is designed

to aid in this effort. The Flight Line Autopilot Tester (P/N 95101) is used to simulate some of the major system

components. It is shown in Fig. 1-1 and contains the following, each removable from a suitcase for remote use about

the aircraft:

The Breakout Box (P/N 9524), Adapter Cables (P/N 39198 & 39199), and Extender Assembly (P/N 01264) are

used to measure autopilot system power, signals, and continuity. They are connected as shown in Fig. 1-2.

The third objective is to determine if the system is functioning properly in flight. This is accomplished by performing

the flight procedures contained in the respective Pilot's Operating Handbook (POH). However, for return of aircraft to

service, refer to the Aircraft Flight Manual Supplement (AFMS).
