Abstract

A system and method to diagnosis an actuator of a flight control system. The system and method includes interfacing a diagnostic computer to the flight control system, commanding movement of an actuator with the diagnostic computer via the flight control system, measuring performance of the actuator via the diagnostic computer, and comparing the measured performance of the actuator with allowable performance values.

Claims (12)

1. A method to diagnosis flight control devices, comprising:

interfacing a portable computer with an aircraft computer;

commanding an actuator with the portable computer via a flight control system of the aircraft computer;

obtaining running friction and breakout friction data of the actuator via the portable computer;

comparing the running friction and breakout friction data of the actuator with allowable performance data stored in a table in the portable computer;

obtaining outside air temperature data via the portable computer;

modifying the allowable performance data according to the outside air temperature data; and

providing notice if the running friction and breakout friction is outside the allowable performance data.

2. The method of claim 1 , wherein the aircraft computer is the flight control system.

3. The method of claim 2 , wherein the actuator is a trim actuator.

4. The method of claim 1 , further comprising:

interfacing a processor with the flight control system that in turn interfaces with the portable computer.
