Abstract
The present invention provides a method and apparatus for testing a valve control system in an aircraft fuel supply system having a plurality of control valves, wherein the control system includes a processor adapted to receive feedback signals from each of the plurality of control valves, the method comprising the steps of: connecting a test device to the control system such that the test device is connected for signal transmission to the processor; outputting a signal to the processor simulating a feedback signal from at least one of the control valves; detecting a control signal which is output by the processor to the at least one of the control valves; and identifying the detected control signal which is output by the processor to the control valve.

A method of testing a valve control system in an aircraft fuel supply system having a plurality of control valves, wherein the control system includes a processor adapted to receive feedback signals from each of the plurality of control valves, the method comprising the steps of:
- connecting a test device to the control system such that the test device is connected for signal transmission to the processor;
- outputting a signal to the processor simulating a feedback signal from at least one of the control valves;
- detecting a control signal which is output by the processor to that one of the control valves;
- and
- identifying the detected control signal which is output by the processor to the control valve.
An apparatus for testing a valve control system in an aircraft fuel supply system having a plurality of control valves, wherein the control system includes a processor adapted to receive feedback signals from each of the plurality of control valves, the apparatus comprising:
- connector means (20) for connection to the control system such that the apparatus is adapted for signal communication with the processor,
- signal means (30) adapted to output a signal to the processor simulating a feedback signal from one or more of the plurality of control valves;
- detector means (40) for detecting a control signal which is output by the processor to that one or more of the plurality of control valves;
- and
- indicator means for identifying the detected control signal output by the processor to the control valve.
