(ARINC)and thePurpose of ARINC CharacteristicsAeronautical Radio, Inc. is a corporation in which the United States scheduled airlines are the principalstockholders. Other stockholders include a variety of other air tra
5、nsport companies, aircraft manufacturers andnon-U.S. airlines.Activities of ARINC include the operation of an extensive system of domestic and overseas aeronauticalland radio stations, the fulfillment of systems requirements to accomplish ground and airborne compatibility, theallocation and assignme
6、nt of frequencies to meet those needs, the coordination incident to standard airbornecommunications and electronics systems and the exchange of technical information. ARINC sponsors theAirlines Electronic Engineering Committee (AEEC), composed of airline technical personnel. The AEECformulates stand
7、ards 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 with the airlineswho have a requirement or anticipate a requirement,
8、 with other aircraft operators, with the Military serviceshaving similar requirements, and with the equipment manufacturers. It is released as an ARINC EquipmentCharacteristic only when the interested airline companies are in general agreement. Such a release does notcommit any airline or ARINC to p
9、urchase equipment so described nor does it establish or indicate recognition ofthe existence of an operational requirement for such equipment, nor does it constitute endorsement of anymanufacturers product designed or built to meet the Characteristic. An ARINC Characteristic has a twofoldpurpose, wh
10、ich is:(1) To indicate to the prospective manufacturers of airline electronic equipment the consideredopinion of the airline technical people, coordinated on an industry basis, concerning requisitesof new equipment, and(2) To channel new equipment designs in a direction which can result in the maxim
11、um possiblestandardization of those physical and electrical characteristics which influence interchangeabilityof equipment without seriously hampering engineering initiative.ARINC CHARACTERISTIC 753TABLE OF CONTENTSITEM SUBJECT PAGEiii1.0 INTRODUCTION 11.1 Purpose of this Document 11.2 Relationship

The standards necessary to ensur
42、e this level ofinterchangeability are set forth in Chapter 2 of thisdocument.1.6 Regulatory ApprovalsThe equipment must meet all applicable regulatoryrequirements. Manufacturers are urged to obtain allnecessary information for such regulatory approval. Thisinformation is not contained in this charac
43、teristic, nor is itavailable from ARINC.ARINC CHARACTERISTIC 753 - Page 32.0 INTERCHANGEABILITY STANDARDS2.1 IntroductionThis chapter sets forth the specific form factor, mountingprovisions, interwiring, input and output interfaces andpower supply characteristics desired for the HF DataRadio and HF
44、Data Unit. These standards permit theparallel, but independent design of compatible equipmentand airframe installations.Unit interchangeability is required for the HF Data Radio,HF Data Unit, and Antenna Coupler, regardless ofmanufacturing source. COMMENTARYIn order to achieve the full benefit of th
45、e economicsoffered by these changes, the industry desires thatany provisions for backwards compatibility withearlier generations of HF Communications equipmentdescribed by ARINC Characteristic 719 be providedas basic provisions. The ARINC 753 transceiver (HFDR) is pin- and function-compatible with t
46、he ARINC 719 transceiver. When an HFData Radio is installed in an ARINC 719 slot, (replacing anARINC 719 transceiver) it should operate with ARINC 719radio functionality. An HF Data Unit attached to thisarray would be required to obtain HF Data Linkfunctionality.2.2 Form Factor, Connector, and Index
47、 Pin CodingThe HFDR and HFDU should comply with the dimensionalstandards in ARINC Specification 600, “Air TransportAvionics Equipment Interfaces (NIC Phase 1)”, for the 6MCU and 4 MCU form factors respectively. The HFDRand HFDU should also comply with ARINC Specification600 standards with respect to
48、 weight, racking attachments,front and rear projections and cooling.COMMENTARYThe only form factor defined in this Characteristic isthe Modular Concept Unit (MCU) defined in ARINCSpecification 600. Packaging of the HFDR inaccordance with ARINC Specification 404A was notconsidered desirable. However,
49、 some retrofitinstallations into aircraft racking for ARINC 404Aequipment are expected.The HFDR and HFDU should each be provided with a lowinsertion force, Size 2 Shell ARINC Specification 600service connector. This connector, which shouldaccommodate service interconnections in its middle plug(MP) and top plug (TP) inserts and powerinterconnections in its bottom plug (BP) insert, should belocated on the center grid of the HFDR and HFDU rearpanel. Index pin code 10 should be used for the HFDR. In
