Patent ID: 8564300

Claim:
A method of testing an aircraft control system, comprising the steps of: coupling a plurality of connection elements of a portable connector unit of an apparatus for testing an aircraft control system to a plurality of separate input points in the aircraft control system to be tested; operatively connecting a hand-held selector unit to the connector unit via a cable, wherein the hand-held selector unit comprises a series switching device, and a detector and indicator device; serially selecting individual ones of each of the plurality of separate input points in the aircraft control system to be tested by actuation of the series switching device of the hand-held selector unit to provide an electrical connection between the selected one of the plurality of separate input points in the aircraft control system to be tested and the hand-held selector unit, wherein all of the plurality of separate input points in the aircraft control system to be tested are individually tested one after the other in a series; and detecting and indicating whether a defined voltage exists at the selected one of the plurality of separate input points in the aircraft control system to be tested using the detector and indicator device of the hand-held selector unit.
