ATA CHAPTER

ATA Description
75 - 7540 Bleed Air Indicating System

Air

The systems which indicate temperature, pressure, control positions and warning indications of turbineengine compressor bleed air systems in turbine engines. Typical parts are transmitter, sensor, indicator,lamp, pressure switch, etc.

34 - 3435 Heads Up Display System

Navigation

The flight instrument system that allows the pilot of an aircraft to watch the flight instruments whilelooking ahead of the aircraft. Includes the display screen which allows information to be visuallypresented to the pilot while looking through the windscreen or at the control panel.

75 - 7597 Engine Bleed Air System Wiring

Air

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

34 - 3436 Wind Shear Detection System

Navigation

The flight instrument system that allows the pilot to detect strong horizontal or vertical wind shift that actsat right angles to the direction the wind is blowing. Includes the outboard sensors, indicators, and thewarning system which notifies the pilot of the appropriate corrective action maneuver to take.

76 - 7600 Engine Controls

Engine Controls

The controls which govern the operation of the engine. Includes units and components which areinterconnected for emergency shutdown. For turboprop engines, includes linkages and controls to thecoordinator or equivalent to the propeller governor, fuel control unit or other units being controlled. Forreciprocating engines, includes controls for blowers. Does not include units or components which arespecifically included in other chapters. For general reports of engine control problems with insufficientinformation to file in a more specific JASC 7600 series code.

34 - 3440 Independent Position Determining System

Navigation

The system which provides information to determine position and is primarily independent of groundinstallations. Use this code for reports of a general nature or for reports containing insufficientinformation to file in a more specific code identified in JASC codes 3441 through 3446. Typical parts arestar tracker, sextants/octants, etc.

76 - 7601 Engine Synchronizing

Engine Controls

The components providing for engine synchronization in multi-engine aircraft.

34 - 3441 Inertial Guidance System

Navigation

The navigation system which relies upon gyro platforms and accelerometers for its operation. Includesthe control panel for the inertial navigation system; the instruments which receives their signal from theInertial Navigation Unit (INU); and the unit containing the inertial platform and digital computer portion ofthe system. Use this JASC code for hardware components which do not have specific JASC codesassigned to them or when a system malfunction or failure occurs but the exact cause is not known.Typical parts are mode selector unit (MSU), control display unit (CDU), remote display unit (RDU), etc.

76 - 7602 Mixture Control

Engine Controls

The control for adjusting fuel-air mixture in piston engines. Includes linkage from the cockpit lever to thecarburetor or fuel injector servo but does not include the arm on mixture control shafts. Typical parts arecable, rod, bellcrank, rod end, housing, clamp and cockpit control lever/knob.

34 - 3442 Weather Radar System

Navigation

The system components and parts which transmits and receives a signal independent of groundfacilities to determine the relative position of adverse weather cells. Typical parts are transceiver,antenna, control panel for the weather avoidance radar system, accessory synchronizers, servoamplifier, scope, etc.
