Engine Controls

The system which provides for control of carburetor or fuel injectors on piston engines; fuel controls orcoordinator on turbine engines; and propeller regulator turboprop engines. Typical parts are cable, rod,rod end, bellcrank, bracket, clamp, actuator, shaft, shaft pin, knob, etc.

Navigation

The airborne radar system which utilizes the Doppler effect to measure and display ground speed, driftangle, cross track, etc.

Engine Controls

The system which provides for rapid, complete shutoff of combustible fluids to the engine compartmentsduring emergency procedures. Typical parts are cable, actuator, switch, lever, etc.

Navigation

The system which detects and alerts flight crew to potential terrain hazards. Includes the antenna whichtransmits and receives an electronic signal for the radio altimeter equipment used for terrain-to-aircraftdistance. Also includes the component which interprets a radio signal reflected back to a receiver todetermine distance from the nearest terrain; and the component which process the warning computerinput signals from various sources in order to determine if and when the crew should be alerted of aterrain hazard.

Engine Controls

For reports indicating a problem with wiring specific to the Engine Control System.

Navigation

The system which provides information to determine aircraft position and is primarily independent ofground installations (i.e., traffic alert and collision avoidance system - TCAS). Use this code only if thespecific system creating the problem cannot be established. Typical parts are collision avoidancemonitoring units, etc.

Engine Indicating

For general reports of engine indicating system discrepancies with insufficient information to file in amore specific JASC 7700 series code. This code is also used for reports with multiple engineindications.

Navigation

The non radar weather system and components which sense the electrostatic charges accumulatedaround a storm cell in order to "map out" that cell on an indicator.

Engine Indicating

For power indicating systems which directly or indirectly indicates power or thrust (i.e., brake meaneffective pressure {BMEP}, engine pressure ratio {EPR}, RPM, etc.) but is not covered in JASC codes7711 through 7722.

Navigation

The system which provides information to determine position and is mainly dependent on groundinstallations. Use this code for reports of a general nature or for those with insufficient information to filein a more specific JASC code identified in JASC codes 3451 through 3457.
