The US Navy's Consolidated Automated Support System (CASS) family of testers is outfitted with three Ai-710 analog test instruments and provides 96 channels of analog test capability, enabling transition from a traditional serial to a parallel test approach. Most CASS test program sets do not take advantage of parallel test capability, which results in long runtimes. In this paper, the authors will...
Naval Air Systems Command (NAVAIR) is responsible for cradle-to-grave development and support of Aircraft Launch and Recovery Equipment (ALRE). As this equipment and its associated development, maintenance, and support become increasingly complex, and the budgetary pressures facing the Navy become increasingly strong, there arises a need for an Integrated Support Environment (ISE) for ALRE. For the...
Demonstrations of avionics system and subsystem diagnostic capability are performed before a system or subsystem is verified. This ordinarily happens during the system design and demonstration phase of a program. In the case of aircraft or ground vehicles, there are several subsystem demonstrations, followed by a single system-level event. By the time a system or subsystem is ready for a functional...
The following topics are dealt with: test efficiency improvement; automatic testing; spectral and vector signal analysis; .NET framework; fault diagnosis; failure prognosis architecture; aircraft testing; system maintenance; digital instrumentation; system modernization; obsolescence; testing reliability; synthetic instrumentation; design testability; software standards and management; RF test; diagnostic...
Health management is becoming increasingly important in expensive and complex machinery such as aircraft, shipboard equipments, and ground vehicles. The diagnosis of failures in such vehicles (or in their subsystems) based on asset condition has been analyzed in-depth in the last few decades, and is relatively well understood. However, prognostic evaluation of faults in machinery, also known as prognostic...
For Aircraft Launch and Recovery Equipment (ALRE), the goal is to get planes in the air and ensure they land safely. Consequently, a high operational availability (Ao) is crucial to ALRE operations. In order to ensure high Ao, it is crucial that the amount of maintenance, both corrective and preventative, is kept to a minimum. Historically, improvements have been reactive in nature to satisfy the...
