3、t shall constitute an acceptancethereof “as is” and be subject to this disclaimer.FOREWORDActivities 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

4、stockholders include a variety of other air transport companies, aircraft manufacturers and non U.S.flag airlines.Activities of ARINC include the operation of an extensive system of domestic and overseas aeronautical landradio stations, the fulfillment of systems requirements to accomplish ground an

5、d airborne compatibility, the allocationand assignment of frequencies to meet those needs, the coordination incident to standard airborne communications andelectronics systems and the exchange of technical information. ARINC sponsors the Airlines Electronic EngineeringCommittee (AEEC), composed of a

6、irline technical personnel. The AEEC formulates standards for electronic equipmentand systems for the airlines. The establishment of Equipment Characteristics is a principal function of this Committee.An ARINC Equipment Characteristic is finalized after investigation and coordination with the airlin

7、es whohave a requirement or anticipate a requirement, with other aircraft operators, with the Military services having similarrequirements, and with the equipment manufacturers. It is released as an ARINC Equipment Characteristic only whenthe interested airline companies are in general agreement. Su

8、ch a release does not commit any airline or ARINC topurchase equipment so described nor does it establish or indicate recognition of the existence of an operationalrequirement for such equipment, not does it constitute endorsement of any manufacturers product designed or built tomeet the Characteris

9、tic. An ARINC Characteristic has a twofold purpose, which is:(1) To indicate to the prospective manufacturers of airline electronic equipment the considered opinion ofthe airline technical people, coordinated on an industry basis, concerning requisites of new equipment,and(2) To channel new equipmen

10、t designs in a direction which can result in the maximum possiblestandardization of those physical and electrical characteristics which influence interchangeability ofequipment without seriously hampering engineering initiative.iiREPLACEMENT PAGE REVISED: November 15, 1991Copyright 1992 byAERONAUTIC

38、ibes highly reliable, low-cost,lightweight airborne weather radar equipment intendedfor installation in commercial transport type aircraft. Itsprimary purpose is weather detection, ranging andanalysis. Its secondary purpose is ground mapping tofacilitate navigation by display of significant landcont

39、ours. Its tertiary purpose is displaying alpha-numeric information from an external source.1.2 Purpose and Limitations to this CharacteristicThis characteristic has been prepared by the Industry totake advantage of recent, technical advances in airborneweather radar. Emphasis is placed upon weatherd

40、etection/analysis capability and performance,reliability, installation ease, digital aircraft systemcompatibility and reduced cost of ownership.COMMENTARYCurrent integrated circuit technology coupled withadvance packaging techniques should also reduceweight and volume of this system. As muchfreedom

41、as possible is given to equipmentdesigners to provide the required performance inthe most efficient manner and to meet individualairlines preferences provided standard packingand interwiring are used. Electrical characteristicof the weather radome are defined in Section 9. Itis to be understood, how

42、ever, that mechanicaldesign must remain the responsibility of theairframe manufacturer.1.3 System Description1.3.1 System ArchitectureThe system should be viewed as a weather sensorconsisting of a Transmitter-Receiver (T-R) and Antennawhich functions through a standardized electricalinterface to the

43、 control and display elements. Thedisplay may consist of a dedicated “Weather RadarIndicator” unit or it may be one of several functions on a“Multi-Function Display” (MFD). The controls may beprovided by a separate unit or integrated into the displaywhere a Control/Display Unit (CDU) is provided. Th

44、isconcept provides for the independent future upgrading ofthe sensor and/or its use with other display systems.COMMENTARYData transfer between units of the system should beprimarily serial digital. Information originatingfrom the control panel or other source should bepresented to the T-R on a seria

45、l digital bus. The T-R should accept properly addressed control inputs,respond to these inputs and relay the selections tothe indicator together with relative azimuth andrange related receiver data. The display shouldaccept the control and range data from the T-R,store the data in digital memory and

46、 display theinformation for the user.1.3.2 System ConfigurationThe standardized units described by this characteristiccan be designed into three basic aircraft installationconfigurations:a. Three Unit/Dedicated Display System Consistsof an Antenna, Transmitter-Receiver and acombined control-Display

47、Unit dedicated forthe exclusive use of the Weather Radar system.b. Three Unit/Multi-Function Display SystemConsists of an Antenna, Transmitter-Receiverand Control Unit with the display functionsprovided through a separate Multi-FunctionDisplay (MFD) system.c. Four Unit System consists of an Antenna,

48、Transmitter-Receiver, Control Unit and adedicated Display Unit.All units should be designed for an installation thatincludes single or dual transmitter-receivers, single ordual controls and/or displays and a single antenna. Blockdiagrams of typical configurations are shown inAttachment 11.The stabil

49、ization signals, control information and displaydata should be serial digital. The stabilization signalsshould conform to ARINC 704 Inertial ReferenceSystem or ARINC 705 Attitude and Heading ReferenceSystem. The control information bus should be the lowspeed type of ARINC 429, “Mark 33 Digital InformationTransfer System (DITS)”. The display data bus shouldconform to the characteristics of the very high speed busdescribed in Appendix 1 to this document.NOTE: The extracts from Draft 2 of the ARINC 453very high speed bus AS SET FORTH IN APPENDIX 1to this document are applicable to this We
