SYSTEM 1.0 INTRODUCTION AND DESCRIPTION 1.1 Purpose of this Characteristic This document is intended to provide design guidance for development and installation of a Qui
18、ck Access Recorder (QAR) which provides an easily accessable stora e of data within an Aircraft Integrated Data System !AIDS) primarily intended for airline use. I 1.1.1 Relationship to ARINC Characteristic 573 The Quick Access Recorder is primarily intended as a complement to an AIDS Mark 2 System
19、as defined by ARINC Characteristic 573 which is composed of a Flight Data Acquisition Unit (FDAU) and a crash protected Digital Flight Data Recorder (DFDR). The first purpose of such an ARINC 573 AIDS is to meet the expanded parameter flight data recording requirements of FAA or other reg- ulatory b
20、odies for accident investigation. However the FDAU defined by ARINC 573 has extra-capability (by itself and/or through optional Auxiliary Data Acquisition Unit ADAU) to accept other input parameters than those required to meet mandatory requirements. Addition of a Quick Access Recorder to the mandat
21、ory sys- tem makes it possible for airlines to take advantage of this extra input capability to acquire parameters for performance monitoring, maintenance monitoring, etc . , thus achieving a low cost, yet effective, minimum size AIDS capability. The QAR may also be used to store the data output of
22、a separate AIDS-oriented acquisition unit (FDAU or other unspecified DAU) , or of a Data Management Unit (DMU), provided the output characteristics of such units are the same as that of ARINC 573 FDAU “DFDR OUTPUT“ (re- fer to Section 2.2). Attachment 1 exhibits some AIDS configurations, including a
23、 QAR, which may be used as an al ternative to the system shown in ARINC 573 Appendix 1. COMMENTARY FDAU and DFDR are the first “building blocks“ of an “Expandable Flight Data Acquisition and Record- ing System“. These two units are basically needed to meet mandatory flight recording, but provide gro
24、wth potential to various AIDS configurations. Addition of a QAR is the first step towards such an expansion. 1.1.2 Relationship to ARINC Characteristic: 563 Apart from the crash-protected “Flight Data Recorder“ , ARINC 563 defined two recorders as possible components of an “AIDS Mark 1“ system, Reco
25、rder“ and the “Long Term Recorder“. The Quick Access Recorder as defined by this Character- istic may combine the main function of both, The amount of data to be stored (both rate and duration) is compati- ble with that “Long Term Recorder“, yet it still complies with the “Quick Access Recorder“ req
26、ui rements of ARINC 563. Thus the name “Quick Access Recorder“ has been These are the “Quick Access - . - kept. However, the QAR defined in this Character- istic does not conform to ARINC 563 as far as form factor is concerned : with the same assumptions . about storage capabilities, present state o
27、f the art allows design of a more compact and lighter recorder. 1.2 Functions and Modes of Operation The basic functions of the QAR are to: a) store the digital data supplied at the output of an ARINC 573 FDAU or other similar AIDS acquisition unit or DMU. b) provide an easy access to these stored d
28、ata for systematic ground processing for perfor- mance monitoring, maintenance monitoring or other purposes. Recording may be continuous , or constant-speed intermittent (for example under DMU control). 1.3 Reliability and Maintainability 1.3.1 Reliability Reliability must be designed and built in a
29、s an integral part of the equipment. COMMENTARY The designer may be surprised to find no elaborate requirements for reliability. The airlines are in a most fortunate position in this regard because they have found the pres- sures of the “market place“ exert a :truly meaningful influence upon the des
30、ign and pro- duction quality control necessary to achieve high equipment reliability, The key advantages enjoyed by the vast majority of airlines is the ability to purchase existing, fully operational equipment “off the shelf“ after the product has established itself in the market. Reduced to ?he si
31、mplest of terms the manufacturer will find that if he does not design it and build it pro- perly, it wont sell. 1.3.2 Maintainabi 1 i ty The equipment should be designed to use replaceable functional modules as far as is practical, in order to faci 1 i tate maintenance. Adequate and effective Bui 1
32、t-In-Test-Equipment (BITE) should be incorporated to identify failures within the QAR. The BITE should clearly distinguish failures of the QAR from other system elements in order to avoid the use of “shotgun“ maintenance on the whole system. COMMENTARY Airlines have found the BITE provided in many o
33、ther systems suffers from the dual fault of being too complex and yet too ineffective. Equipment designers are urged to avoid both pi tfal Is! cr ARINC 591 72 O307637 0003324 4 li ARINC CHARACTERISTIC 591 Page 2 1 .O INTRODUCTION AND DESCRIPTION 1.4 Unit Description The Quick Access Recorder is a ma
34、gnetic tape (or wire) recorder in which the magnetic medium is contained in an easily removable “cassette“ in order to provide an easy access to stored data. The cassette is described further in Section 3.7. The QAR also contains the necessary circuitry to control tape transport, drive magnetic head
35、s, and determine status to facilitate maintenance as set forth in Section 3.5. 1.5 Interchangeability “Unit interchangeability“ as defined in Section 2.0 of ARINC Report Number 403 is required for the Quick Access Recorder regardless of the manufacturing source, The detailed requirements intended to
36、 ensure satisfactory interchangeability are set forth in Section 2.0 “Standards Required to Effect Interchangeabi 1 i ty“. These require- ments will enable the airframe manufacturer and airline to manage space and wiring provisions (especially inter- wiring between FDAU and WAR) regardless of the ma
37、nufac- turing source. They will also allow use of the same type of QAR by an individual airline in different fleets of aircraft regardless of the AIDS configurations of these fleets and without any flight line adjustment. COMMENTARY Interchangeability is not specified for the “cas- sette“. Thus use
38、of any QAR from any manufacturer remains possible on an individual aircraft but needs the availability of the corresponding ground pro- cessi ng equipment, 1 .6 Regula tory Approval In the absence of a current TSO for the QAR, direct regu- latory approval of this unit cannot be obtained. The install
39、ation will normally be approved as part of the original equipment on the aircraft or by a supplemental Type Certificate. The equipment manufacturer should re- fer to Section 2.6 of this Characteristic for the envi- ronmental requirements. In this regard, the reader is also referred to Section 1.3.5
40、and 1.3.6 of ARINC Report 414 “General Guidance for Equipment Installation Designers for further information on this subject. 1.7 Applicable Publications, Spec and Reports The reader is referred to ARINC Report No. 414, “General Guidance for Equipment and Installation Designers“, and specifically Ap

42、FFECT INTERCHANGEABILITY It is of prime importance that the Industry establish specific form factors, mounting provisions, interwiring, input and output interfaces and power supply requirements for the Data Link equipment. These standards are neces- sary to ensure the continued independent design an
43、d development of both the equipment and the airframe instal- lation. It should be noted that although this ARINC document does not preclude the use of different form factors and inter- wiring features, the practical problem of re-designing accommodate some special system could very well make the use
44、 of that other design prohibitively expensive for the customer. Thus, manufacturers should recognize the practical advantages of developing equipment in accordance with the form factor, interwiring and output interface standards of this Document. what will then be a standard aircraft installation to

The corresponding aircraft connector is

COMMENTARY The one-half ATR form factor was selected by the airline
