T70x Engine Indications Test Set Adapter

The U.S. Coast Guard operates MH-60 rotary wing aircraft to perform various missions to include Search & Rescue, Law Enforcement, and Department of Defense Military Exercises. The aircraft routinely operate in conjunction with the civil aircraft and as such must comply with all Federal Aviation Administration (FAA) regulations. To ensure safety of flight there is an emerging requirement to test and validate engine indications and fuel quantity indications. A requirement exists to provision a T70x Engine Indications Test Set Adapter that interfaces with the Series II. These parameters should be simulated via an analog discrete communication standard which will be interpreted through the aircraft architecture and displayed on the Common Avionic Architecture System (CAAS) Engine Instrument Caution Advisory System (EICAS). These indications shall include but are not limited to: Gas Generator Speed (Ng), Turbine Gas Temperature (TGT), Power Turbine Speed (Np), Rotor Speed (Nr), Engine Torque, All installed chip detectors for engines and gearboxes, Engine and main gearbox oil temperature and pressure, Oil filter bypass indications, and Fuel quantity indicators for inboard and external tanks. The test set needs to provide the interconnecting and power control which allows maintenance personnel to simulate specific inputs required for calibration and testing of the systems associated with the indication above. The MH-60T test set will interface with the aircraft wiring harness through the installed cannon plugs and provide an appropriate signal to simulate engine and fuel indication parameters.
