Abstract: An informational/positional guide, which is disposable in an aircraft instrumentation interface, used with at least one mechanical guide key configured to guide interface engagement, and the guide key having an orientation specific to a particular type of aircraft equipment configuration, the guide is provided with a key engagement member. The key engagement member is formed to engage the guide key and is disposable in a variety of angular orientations to facilitate engagement with the guide key. The key engagement member is further provided with an aircraft equipment configuration sensor for identifying the aircraft equipment configuration type in response to sensed orientation of the key engagement member and for generating an electronic signal in response to the identification of the orientation of the key engagement member.

Abstract: In accordance with the present invention, an aircraft instrumentation interface for use with at least one electrically conductive mechanical key disposed in an interface connector and has an orientation specific to a particular type of aircraft equipment configuration. The interface is provided with a key engagement member which is formed to electrically engage the mechanical key for sensing the angular orientation of the mechanical key. The interface is further provided with an aircraft equipment configuration sensor for identifying the aircraft equipment configuration type in response to sensed orientation of the mechanical key and for generating an electrical signal in response to the identification of the orientation of the mechanical key.

Abstract: An aircraft engine vibration analysis system is provided with at least one vibration sensor disposed proximate an aircraft engine. The analysis system is further provided with a vibration analysis module for receiving an input from the vibration sensor and generating an output representative of vibration characteristics of the aircraft engine. The analysis module is provided with a multiple pin input port which is connectable to the vibration sensor. The analysis module is further provided with test sequence select circuity which is in electrical communication with the input port for implementing an appropriate vibration analysis sequence in response to measured conductivity between pins of the multiple pin input port. The analysis system is further provided with a sensor connecting cable which is connectable to the vibration sensor and the analysis module input port.
