4、mmitteeSpecification 601 Adopted by the Airlines Electronic Engineering Committee: August 31, 1979iiFOREWORDActivities of AERONAUTICAL RADIO, INC. (ARINC)and thePurpose of ARINC Reports and SpecificationsAeronautical Radio, Inc., is a corporation in which the United States scheduled airlines are the
5、 principalstockholders. Other stockholders include a variety of other air transport companies, aircraft manufacturers and non-U.S.airlines.Activities of ARINC include the operation of an extensive system of domestic and overseas aeronautical landradio stations, the fulfillment of systems requirement
6、s to accomplish ground and 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 EngineeringCommit
7、tee (AEEC), composed of airline 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.It is desirable to reference certain general ARINC Specifications or Repor
8、ts which are applicable to more thanone type of equipment. These general Specifications or Reports may be considered as supplementary to the EquipmentCharacteristics in which they are referenced. They are intended to set forth the desires of the airlines pertaining tocomponents and general design, c
9、onstruction and test criteria, in order to insure satisfactory operation and the necessaryinterchangeability in airline service. The release of a Specification or Equipment Characteristic should not be construedto obligate ARINC or any airline insofar as the purchase of any components or equipment i
10、s concerned.An ARINC Report (Specification or Characteri stic) has a twofold purpose, which is:(1) To indicate to the prospective manufacturers of airline electronic equipment the considered opinion of theairline technical people coordinated on an industry basis concerning requisites of new equipmen
11、t, and(2) To channel new equipment designs in a direction which can result in the maximum possible standardizationof those physical and electrical characteristics which influence interchangeability of equipment withoutseriously hampering engineering initiative.iiiPREFACETOARINC SPECIFICATION 601Sinc
12、e 1970 a great deal of work has been put forth by ARINC, Airlines, Airframe manufacturers, and avionics suppliersto upgrade existing documents which control avionics thermal characteristics. This effort was justified by theincreasingly apparent inverse relationships between equipment operating tempe
13、rature and reliability levels.This same awareness led to the development and publication of the new avionics equipment interface document “ARINCSPECIFICATION 600.”With the other new and revised ARINC Specifications (600, 404A and 408A) the majority of traditionally active radioswere covered. Current
14、 trends in electronics however, have made it necessary to develop this additional Specification.The trends involved are the new CRT Displays and the trend for active electronic circuitry to be encased in whattraditionally has been control boxes with passive components only.Recognizing the changing d
15、esign philosophy as well as state-of-the-art changes, it was considered advisable to generatethis additional Specification which is intended to include all flight deck electronics not currently included in ARINC404A, 408A, or 600. Specifically included are:+ Glare shield area+ Overhead panel area+ S
16、ide panel area+ Pedestal+ Instrument Panel (those equipment not covered by ARINC 408A)+ Flight Engineers ConsoleThere is no intent implicit in the issuance of this ARINC Specification to deprecate or derogate any existing ARINCSpecification. This Specification is expected to fill the need for standa
17、rds of thermal design for those equipments whereexisting Specifications are not applicable.REFERENCES1. ARINC Specification 404A, “Air Transport Equipment Cases and Racking”.2.

31、dingthermal design guidance for the avionic units and theirinstallation in the flight deck area of transport aircraft.Earlier industry packaging developments evolved into theindicator cases and mounting boxes which have beencovered by ARINC Specification 408 since 1960.Present industry experience ha
32、s demonstrated the needfor new concepts to avoid problems resulting from thegrowing complexity of avionic control and displayequipment.COMMENTARYARINC 408A is not superseded by this document,but rather, supplemented by it. There will continueto be avionic indicators best serviced by ARINC408A after
33、ARINC 601 is issued. Section 1.7provides further information on the relationshipsbetween these documents.1.1 ObjectiveThe objective of this document is to provide a system forthe effective control of the environment for avionicequipment. This includes:A. BASIC DESIGN STANDARDS for avionicequipment a
34、nd its installation to assure suitablethermal interfaces (Chapter 2).B. DESIGN CRITERIA AND GUIDANCE TOprovide further details concerning the equipmentand installations (Chapter 3).C. COOLING APPRAISAL to provide data whichshould be utilized by users or equipment andaircraft manufacturers to confirm
35、 the equipmentthermal design and to show compatibility withaircraft environment (Chapter 4).Inherent in this objective is the principle that failure ofthe LRU resulting from the mechanical, electrical andenvironmental interfaces encountered on the aircraft canbe minimized and that aircraft providing
36、 the interfaces asstated herein should not be held responsible for failures ofthis nature.COMMENTARYThis Specification is provided for use by thecommercial air transport industry, the airlineoperators, the airframe manufacturers and theequipment manufacturers. The AEEC Subcom-mittees on systems and
37、subsystems should adhere tothe guidance provided herein when creatingCharacteristics for new systems. Military andgeneral aviation organizations are also encouragedto utilize this Specification, where appropriate, fortheir aircraft avionic equipment and installations.1.2 Installation Locations1.2.1
38、Instrument Panel Mounted EquipmentThree types of equipment other than instrumentsfrequently are installed in the instrument panels ofaircraft: Control, Display and combined Control/Displayunits. These equipments are included in that the thermalcharacteristics are specified but the electrical interfa
39、cesare not. In addition, recent developments have addedCRT Instruments as a new equipment in the instrumentpanel area. CRT Instrument mechanical and thermalinterface needs are covered herein.COMMENTARYThe control and display units which are designedinto the instrument panel historically have beenuni
40、que to the aircraft in most instances. For thisreason it is considered that the standardization,where considered by the users to be necessary, willbe covered in the ARINC EquipmentCharacteristics for the particular system.Electronic flight and engine instruments (CRTInstruments) are considered to be
41、 common to manyaircraft for the future and therefore require standardtray mounting form factor considerations as well ascontrolled thermal characteristics.The mechanical characteristics for CRT instrumentcases are described in Section 2.12.1.2.2 Pedestal Mounted EquipmentThis Specification describes
42、 the standard mechanical andthermal interfaces between the aircraft pedestal and theequipment. The Military Standard MS25212 (DZUS)form factor and mechanical interfaces, as shown inAttachment 2, are normally used for pedestal mountedequipment. The equipment thermal interface described inSection 2 of
43、 this document applies to all pedestalmounted equipment. The configuration of all pedestalmounted equipment should conform to the MS25212DZUS mounting described in Section 3.2.2.COMMENTARYThe use of the pedestal area for simple controls hasbeen traditional on commercial aircraft. Recently,however, m
44、ore active electronic circuitry has beenincluded in control units. The increased thermaldissipation has resulted in increased operatingtemperatures and decreased reliability. It is theintent of this document to provide the coolingstandards needed to assure an optimum reliabilitylevel without imposin
45、g undue design limits.1.2.3 Glare Shield and Side Panel MountedEquipmentControls and displays mounted in the Glare Shield andSide Panels traditionally have been unique designs foreach aircraft configuration. This document does notdefine the mechanical interface, but guidance is providedfor cooling t
46、hese units.ARINC SPECIFICATION 601 - Page 21.0 GENERAL CONSIDERATIONS (contd)1.2.3 Glare Shield and Side Panel Mounted Equip-ment (contd)COMMENTARYSince the equipment normally installed in theseareas is usually considered unique to the aircraftdesign, it is not logical to require standardization ofm
47、echanical configuration or electrical interface.From a thermal standpoint, however, there is asmuch to gain from proper cooling on equipment inthese areas as for equipment in the radio rack orinstrument panel.1.2.4 Overhead and Flight Engineers PanelsUnits used in the overhead and Flight Engineers p
48、anelstraditionally have used the Military Standard MS25212(DZUS) form factor and some type of passive cooling.This document uses the DZUS mechanical interface anddefines three categories of cooling.1.3 Cooling Air Ducts and PlenumsDucting and plenums should be provided as an integralpart of the airc
49、raft equipment mounting, or on adjacentstructure, to direct the flow of cooling air through oraround the LRU. Apertures are defined for each LRU toprovide for passage of the cooling air through the unitwhere flow-through cooling is provided.1.4 Standard International (S.I.) UnitsMost parameters are expressed in “English” units with theequivalent Standard International (S.I.) units.COMMENTARYThe need to retain compatibility with ARINC 408Adimensions and tolerances dictates the use of theestablished “English” units in this document.However, other parameters, such as temperature and
