Engine Indicating

The system which sense, measures, and indicates the engine pressure ratio (EPR) of an turbine engine.The system measures the difference between the compressor inlet pressure and the turbine dischargepressure. Typical parts are sensor, transducer, transmitter, probe, etc.

Navigation

The systems which measures time-to-station, ground speed, and distance to a known transmitterlocation by transmitting and receiving electronic pulse signals (i.e., distance measuring equipment -DME; ultra high frequency tactical air navigational aid - TACAN). Typical parts are antenna, control unit,transceiver, coaxial cables, etc.

Engine Indicating

The system that senses and measures brake mean effective pressure (BMEP) or engine torque in turbopropand piston engines. Does not include internal parts which are type certificated with the engine.Typical parts are indicator, line, sensor, transmitter, pressure switch, etc.

Navigation

The air traffic control (ATC) system which receives coded signals from a ground station and transmits acoded reply for altitude reporting and identification purposes. Typical parts are transponder, antenna,control unit, transceiver, coaxial connecting cables, etc.

Engine Indicating

The reciprocating engine manifold pressure (MP) indicating system including the indicator and sensor.Typical parts are lines, hoses and fittings.

Navigation

The radio navigation system and associated components and parts which provides for long rangenavigation (LORAN) enroute when operating on signals from ground based master and slavetransmitting stations. Typical parts are antenna, coupler, CPU, receiver, indicator, etc.

Engine Indicating

The system including the indicator and sensor which indicates engine speed in revolutions per minute(RPM). Typical parts are, cable, connector, tachometer, tachometer generator, N1 indicator.

Navigation

The radio navigation system in the very high frequency (VHF) band used for determining positionrelative to a ground transmitter and permits selection of an infinite number of magnetic courses fornavigation to a transmitter (i.e., visual omnirange - VOR system). Typical parts are receiver, antenna,control panel, etc.

Engine Indicating

For general reports of the system components and parts which indicate engine temperature withinsufficient information to file in a more specific JASC 7700 series code.

Navigation

The low frequency band system which receives a signal from a non-directional radio beacon todetermine relative position from the beacon location (i.e., automatic direction finder - ADF system).Typical parts are antenna, control unit, receiver, coaxial cables, etc.
