| 65 - 6540 Tail Rotor Drive Indicating System |
Tail Rotor Drive The indicators, sensors, transmitters, and associated systems which indicates operation or activation ofthe tail rotor drive system. |
| 31 - 3140 Central Computers |
Instruments The systems and components used for computing data from a number of different sources without apreponderance of functions in any one system, for call up on a display. Includes integrated instrumentsystems such as engine, airplane power and central warning indicators when combined into a centraldisplay. Typical parts are "digital core avionic system" (DCAS), "engine indications and crew alertingsystem" (EICAS), stored checklist, emergency procedures, company regulations, etc. |
| 65 - 6597 Tail Rotor Drive System Wiring |
Tail Rotor Drive For reports indicating a problem with wiring specific to the Tail Rotor Drive System. |
| 31 - 3150 Central Warning |
Instruments The panels and associated circuitry which warn of potential problems in two or more independent orrelated systems. Warnings can be either audible or visual. Typical parts are annunciator panel, relay,lamp, PC board, diode, throttle microswitch, etc. |
| 67 - 6700 Rotorcraft Flight Control |
Rotors Flight Control For general reports of rotorcraft control systems with insufficient information to file in a more specific6700 JASC series code; or for reports which affect both main and tail rotor control systems. Avoidexcessive use of this code if possible. |
| 31 - 3160 Central Display |
Instruments The systems and components which give visual display of conditions in unrelated systems. |
| 67 - 6710 Main Rotor Control |
Rotors Flight Control The system components and parts other than the servo control system which control and indicates theattitude or the angle of attack of the main rotor blades. Typical parts are collective pitch lever, cyclicpitch stick, coupling and mixing units, and position indicators, etc. |
| 31 - 3170 Automatic Data |
Instruments The systems and components used for collating and computing data from unrelated systems andtransmitting the same automatically. Includes "aircraft to satellite data relay" (ASDAR) system andcomponents. |
| 67 - 6711 Tilt Rotor Flight Control |
Rotors Flight Control The system components and parts of the tilt rotor control system which controls the attitude of theaircraft by rotating the dual main rotor assembly through a 90-degree position. The zero or verticalposition allows vertical takeoff and landing of the aircraft. |
| 31 - 3197 Instrument System Wiring |
Instruments For reports indicating a problem with wiring specific to the Instrument Systems. |
