5、AERONAUTICAL RADIO, INC. (ARINC)and thePurpose of ARINC CharacteristicsAeronautical Radio, Inc. is a corporation in which the United States scheduled airlines are theprincipal stockholders. Other stockholders include a variety of other air transport companies, aircraftmanufacturers and non-U.S. airl
6、ines.Activities of ARINC include the operation of an extensive system of domestic and overseasaeronautical land radio stations, the fulfillment of systems requirements to accomplish ground andairborne compatibility, the allocation and assignment of frequencies to meet those needs, thecoordination in
7、cident to standard airborne compatibility, the allocation and assignment of frequenciesto meet those needs, the coordination incident to standard airborne communications and electronicssystems and the exchange of technical information. ARINC sponsors the Airlines ElectronicEngineering Committee (AEE
8、C), composed of airline technical personnel. The AEEC formulatesstandards for electronic equipment and systems for the airlines. The establishment of EquipmentCharacteristics is a principal function of this Committee.An ARINC Equipment Characteristic is finalized after investigation and coordination
9、 with theairlines who have a requirement or anticipate a requirement, with other aircraft operators, with theMilitary services having similar requirements, and with the equipment manufacturers. It is released asan ARINC Equipment Characteristic only when the interested airline companies are in gener
10、alagreement. Such a release does not commit any airline or ARINC to purchase equipment so describednor does it establish or indicate recognition of the existence of an operational requirement for suchequipment, not does it constitute endorsement of any manufacturers product designed or built to meet
11、the Characteristic. An ARINC Characteristic has a twofold purpose, which is:(1) To indicate to the prospective manufacturers of airline electronic equipment theconsidered opinion of the airline technical people, coordinated on an industry basis,concerning requisites of new equipment, and(2) To chann
12、el new equipment designs in a direction which can result in the maximumpossible standardization of those physical and electrical characteristics which influenceinterchangeability of equipment without seriously hampering engineering initiative.iiARINC CHARACTERISTIC 760TABLE OF CONTENTSITEM SUBJECT P
