6、 Committee: October 13, 1983iiFOREWORDActivities of AERONAUTICAL RADIO, INC. (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 transpor
7、t companies, aircraft manufacturers andforeign flag 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 assignmen
8、t of frequencies to meet those needs, the coordination incident to standard airbornecommunications and electronics systems and the exchange of technical information. ARINC sponsors the AirlinesElectronic Engineering Committee (AEEC), composed of airline technical personnel. The AEEC formulatesstanda
9、rds for electronic equipment and systems for the airlines. The establishment of Equipment Characteristics is aprincipal function of this Committee.An ARINC Equipment Characteristic is finalized after investigation and coordination with the airlines whohave a requirement or anticipate a requirement,
10、with other aircraft operators, with the Military services havingsimilar requirements, and with the equipment manufacturers. It is released as an ARINC Equipment Characteristiconly when the interested airline companies are in general agreement. Such a release does not commit any airline orARINC to pu
11、rchase equipment so described nor does it establish or indicate recognition of the existence of anoperational requirement for such equipment, nor does it constitute endorsement of any manufacturers productdesigned or built to meet the Characteristic. An ARINC Characteristic has a twofold purpose, wh
12、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 requisites ofnew equipment, and(2) To channel new equipment designs in a direction which can result in the maxim
13、um possiblestandardization of those physical and electrical characteristics which influence interchangeabilityof equipment without seriously hampering engineering initiative.REPLACEMENT PAGE REVISED:June 27, 1984TABLE OF CONTENTSARINC CHARACTERISTIC 719ITEM SUBJECT PAGE1.0 INTRODUCTION AND DESCRIPTI

30、IPTION1.1 Purpose of this DocumentThis document sets forth the desired characteristics of a newgeneration HF/SSB system intended for installation in alltypes of commercial transport aircraft. The intent of thisdocument is to provide general and specific design guidancefor the development and install
31、ation of a HF Transceiverprimarily for airline use. It will describe the desiredoperation capability of the equipment and the standardnecessary to ensure interchangeability.Equipment manufacturers should note that this documentencourages them to produce maintenance-free, highperformance equipment ra
32、ther than that of minimum weightand size. They are at liberty to accomplish this objective bymeans of the techniques they consider to be the mostappropriate. Their airline customers are interested primarilyin the end result rather than the means employed to achieveit.1.2 Function of EquipmentThis Ch
33、aracteristic covers the requirements for an airbornetransmitter-receiver equipment capable of transmitting andreceiving HF radio intelligence in the following forms:(a) SSB-full carrier transmission of voice and tonesignals and AM-double sideband reception.(b) SSB-suppressed carrier transmission and
34、 SSB-suppressed carrier reception of voice and othersignals not critical of exact frequencysynchronism.(c) Transmission and reception capabilities (usingexternal coding and keying equipment which isnot made a part of this Characteristic) for specialdata applications.Although the HF/SSB System should
35、 contain the capa-bilities under (c) above, the external coding and keyingequipment to operate with those capabilities is not detailed inthis Equipment Characteristic, nor is it likely to be purchasedby the customer at this time. The user desires the capabilitiesin the HF/SSB System to accommodate d
36、ata transmission at alater date without subsequent modification.Eventually this equipment will be used exclusively in a 3 kHzchannel spaced HF/SSB frequency plan. However, fullcompatibility with the present International Tele-communications Union (ITU) and International CivilAviation Organization (I
37、CAO) AM frequency plan will beneeded until the HF/SSB plan is implemented. Further thecapability of transmitting and receiving full carriertransmission of tones (A2H) will continue to be needed withthe future 3 kHz HF/SSB plan for the ICAO SELCALservice.1.3 Unit Description1.3.1 HF Transceiver UnitT
38、he HF Transceiver unit should house all the components,electronics circuitry, etc., incident to channel selection,receiving and transmitting functions of HF communications.1.3.2 Frequency ControlManual frequency control of the HF Transceiver should beaccomplished from a HF frequency control unit or
39、theequivalent data input from a centralized radio managementsystem. The HF Transceiver control should utilize the 2-wire serial digital frequency/function selection systemdefined in ARINC Specification 429.1.3.3 Antenna Tuner (With Self-Contained or SeparateAntenna Tuner Control)Although a suitable
40、antenna Tuner and Tuner Control shouldbe provided by the manufacturers supplying equipment tothis Characteristic, the equipment manufacturer should alsodesign his SSB equipment to work with existing automaticantenna tuner units of the type designed for SSB operation,and presently installed in many a
41、ircraft.1.4 Interchangeability1.4.1 GeneralOne of the primary functions of an ARINC EquipmentCharacteristic is to designate, in addition to certainperformance parameters, the interchangeability in an aircraftof equipment produced by various manufacturers. Themanufacturer is referred to Section 1.6 o
42、f ARINC Report 414for definitions of terms and general requirements for theairline industry for interchange-ability. As expalined in thatreport, the degree of interchangeability considered necessaryand attainable for each particular system is specified in thepertinent ARINC Equipment Characteristic
43、for that system.1.4.2 Interchangeability Desired for the ARINC 719 HFTransceiverUnit interchangeability is required for the transceiverregardless of manufacturing source. In recognition of thewidely varying control unit designs expected in the future,unit interchangeability is not sought in the cont
44、rol unitexcept, however, that electrical interface of controls shouldconform to the digital signal standards set forth in thisCharacteristic.1.4.3 “Generation Interchangeability” ConsiderationsIn defining the equipment described in this Characteristic, theair transport industry has chosen to depart
45、from several of itsprevious HF transceiver standards. In order to achieve thefull benefit of the economics offered by these changes, theindustry desires that no provisions be made in the equipmentfor backward compatibility with earlier generations of HFCommunication equipment.Unchanged, however, is
46、the industrys traditional desire thatfuture evolutionary equipment improvements and theinclusion of additional functions in new equipments duringthe next few years, do not violate the interwiring and formfactor standards set forth in this document. Provisions toensure forward-looking “generation int
47、erchangeability” (asbest can be predicated) are included in this document toguide manufacturers in future developments.ARINC CHARACTERISTIC 719 - Page 21.0 INTRODUCTION AND DESCRIPTION (contd)1.5 Regulatory ApprovalThe equipment must meet all applicable FAA and GCCregulatory requirements. Manufactur
48、ers are urged to obtainall necessary information from the FAA and the FCC or suchregulatory approval. This information is not contained in thisCharacteristic, nor is it available from ARINC.1.6 System ParametersSystem parameters applicable to HF communications maybe found in the Appendices to this C
49、haracteristic.1.7 Additional Needs of Military CustomersMilitary users of airborne HF/SSB traditionally have hadsome additional needs that dictate features not desired bycivil users. The most significant of these features are:extended frequency coverage, tenth-kHz channel selectionand wide band transmitter/ receiver audio baseband.Some military people confirmed these same featureswould continue to be needed in future equipment anddesigners might wish to include provisions in theequipment to satisfy a future military market. The civilusers approved the addition of guidance materialco
