That message is that through the yearsmany of the customers needs h

21、ave not been met by thetest equipment hardware and documentation.Many of the items in this document reflect the collectiveexperience of numerous airlines (and other users) overmany years and, therefore, should not be taken lightly.Some items have been added to include the impact ofnew technology.It

22、is not intended that this document provide the elementsof a “form, fit, and function” specification. Its purpose isto be a guideline to the kind of test equipment and testcapability the airlines collectively believe they need. Thepast experience of many users has been that most of theavailable test

23、equipment was too expensive, with little orno commonality (hardware or software). This resulted intoo much unique test equipment, with limitedapplicability, much higher acquisition and operating cost,and costly early obsolescence.It is recognized that negative generalizations serve nouseful purpose

24、unless they are accompanied by positiveguidance. Therefore, this document is an industry effortat giving guidance in areas where standardization willbenefit all concerned. It is not an effort to definestandard testers.ARINC REPORT 602A Page 22.0 OBJECTIVES AND SCOPE2.1 ObjectivesThis document define

25、s the users needs and desiresregarding essential attributes of the test equipment to beused for maintenance and troubleshooting of air transportavionics.COMMENTARYThis document is prompted both by the need for testequipment to be cost effective and by the need toaccommodate the increasing number of

26、digitaldesign black boxes in the maintenance functions.This proliferation of digital equipment has requiredthe acquisition of additional, and usually costly, testequipment beyond that required for servicing andmaintaining prior generations of analog equipment.Despite the added complexities, most air

27、lines donot wish to surrender the maintenance to suppliersof the equipment, or to other organizations outsideof the administrative control.2.2 ScopeThis document describes, in general terms, the hardwareand software needed to test and troubleshoot avionicequipment. This avionic equipment includes th

28、e linereplaceable units (LRUs) and LRU subassemblies in theshop, plus the “ramp” equipment needed to identify thespecific failed LRU on the flight line.ARINC REPORT 602A Page 33.0 DOCUMENTATION3.1 GeneralTest equipment manuals should be divided into sections,with each section useable for either ramp

29、 or shopapplication, regardless of whether the test equipment isautomatic or manual. The complexity of manuals willaccordingly change with the complexity of the applicabletest equipment.It should be recognized that test equipment may requireperiodic recalibration under regulatory control.Consequentl

30、y, a unique calibration verification section maybe required in the manual (see 3.3 below). Automatic TestSystems consisting of multiple units may be complex andrequire special consideration and attention. Identification ofperformance specifications at the UUT interface should beincluded in the manua

31、l. A few examples are:A. Definition of expected composite performance andspecifications resulting from multiple test equipmentunits interacting with each other.B. Definition of specifications at three levels:1. At subunit terminals or interface2. At universal interface terminals or interface3. At UU

32、T terminals or interface, such as at a TUA(this may be in the specification for the TUA or theUUT interface adaptor).C. Changes to system performance specifications causedby hardware/software enhancement or degradationwhen using UUT interface adapters (Interconnect Units,vendor modules, etc.). These

33、 changes should bethoroughly documented in appropriate instructionmanuals.D. Identification of those subunits of the system which areindependent of system performance (these are subunitswhich may be recalibrated or replaced independently ofsystem recalibration).Test equipment manuals should be well-

34、indexed andpartitioned into user and maintenance sections as required.Revision control should be maintained with the manual.Documentation for test equipment should be in accordancewith ATA Specification 101/102, with format conforming,in general to ATA Specification 10(see 3.2 below).3.2 Instruction

35、 Manual ContentsThe general format for instruction manuals for testequipment should be similar to Avionics ComponentMaintenance Manuals (CMM) for ease of use andfamiliarity (see ATA Specification 100).All manuals for shop or ramp test equipment should contain,as a minimum:A. IndexB. Functional and P

36、erformance SpecificationsC. Functional Description and Theory of OperationD. Installation and Operation InstructionsE. Calibration Verification Procedures (see 3.2.1 and3.2.2)F. Fault Analysis, Troubleshooting, Repair and AlignmentTables and Procedures (see 3.2.3)G. Illustrated Parts Lists (see 3.2.

37、4)H. SchematicsI. Software DescriptionJ. Firmware Description3.2.1 Calibration/No-Calibration Required DecisionAn instrument should be classified as No-CalibrationRequired (NCR) if it meets the criteria of the guide providedin Attachment 2.3.2.2 Periodic Calibration VerificationWhen calibration is n

38、ecessary, as determined by thecalibration/no-calibration required decision (3.2.1), theinstruction manual should contain sufficient information toverify calibration. This information should also be useablein new unit performance tests and should contain, as aminimum:A. Calibration Specification Tabl

39、e, listing parametercharacteristics and describing how tested.B. Supporting Equipment Table, listing minimum-use-specifications of measurement standards and supporttest equipment (with representative type of equipment,by manufacturer/model, whose published specificationsare applicable).C. Preliminar

40、y and Functional Tests, in numbered/narrative step-by-step format.D. Detailed Numbered/Narrative Step-by-Step calibrationProcedure, including test set-up diagrams, checklists,and data sheets with tolerance limits keyed to 3.2.2Aabove.3.2.3 Tables and ProceduresFault analysis, troubleshooting, repair

41、 and alignment mayrequire certain tables and procedures (see 3.2.F). Whenrequired, these tables and procedures should be innumbered/narrative step-by-step format, including layoutdrawings, parts location aids, schematics, waveform/timingdiagrams, signature analysis codes, etc.3.2.4 Illustrated Parts

42、 ListsIllustrated parts lists should be included in all manuals (see3.2.G). These lists should contain circuit designators, completegeneric descriptions, test equipment manufacturers partnumbers, and part manufacturers part numbers .-2ARINC REPORT 602A Page 43.0 DOCUMENTATION (contd)3.3 Specificatio

43、n/Calibration TraceabilityCalibration of certain test equipment is under regulatorycontrol, depending upon the regulations and laws applicableto the operation and maintenance of the aircraft. In thosecases where national or international laws or regulationsrequire calibration or test equipment, trac

44、eability of suchcalibration is normally also required.Specifics relating to the form and contents of documentationnecessary to provide traceability may vary according to thetype and application of the test equipment, or according tospecific arrangements between the manufacturer and user.Calibration

45、information delivered with new test equipmentshould be in such format and contain sufficient calibrationand documentation instructions to comply with appropriateinternational, national, or local regulatory body require-ments.Calibration instructions should be in sufficient detail toensure that prope

46、r calibration can be performed by the useror other approved calibration facility.Documentation necessary to comply with regulatoryrequirements should be provided with the test equipment,and should be in such a format that traceability of calibrationis ensured.COMMENTARYMany users desire to repair an

47、d calibrate testequipment within their own facilities. Necessaryinformation should be supplied with the testequipment to insure that this can be done properly.This calibration/repair information should includespecifications, as necessary, for subassemblies notbuilt by the major test equipment manufa

48、cturer, butincluded as a part of the test equipment.REVISED: February 1, 1996ARINC REPORT 602A Page 54.0 TEST EQUIPMENT CLASSIFICATION*4.1 GeneralThe term “avionics test equipment,” as used in thisdocument, describes the equipment necessary formaintenance and troubleshooting of avionics units/system

49、s.This test equipment can be classified into overlappingcategories according to the desired application. The user hascertain constraints, such as anticipated work flow, initialinvestment, training/competency level of maintenancepersonnel, nature of their aircraft fleet, complexity ofavionics, and maintenance history of avionics. Theseconstraints play an important role in determining a cost-effective mix of avionics test equipment for the user. Onlythe user can determine the proper mix for his particularoperation. However, this document outlines the basicgroupings of such test
