An apparatus and method are provided for evaluating the operational status of a weapon interface system ("WIS") for coupling an aircraft controller to a plurality of weapon systems and a corresponding plurality of weapon ejectors. The WIS to be evaluated includes a weapon system interface unit ("WSIU"), a power switching unit ("PSU"), and a power distribution box ("PDB"). The apparatus of the invention includes an input/output device removably coupled to a first WSIU port for generating a first test signal and providing the first test signal to the first WSIU port, and a processor mounted in the WIS and operatively coupled to the first WSIU port and to a selected portion of the WIS to be tested for generating a second test signal in response to the first test signal and communicating the second test signal to the selected portion to cause the selected portion to communicate a response signal to the processor corresponding to the state of the selected portion and for generating an output signal in response to and corresponding to the response signal and communicating the output signal to the input/output device. |
