1、AEROSPACE RECOMMENDED PRACTICEARP4102/15REV.AIssued 1993-02Revised 2000-07Superseding ARP4102/15Electronic Data Management System (EDMS)1. SCOPE:This SAE Aerospace Recommended Practice (ARP) recommends criteria for an Electronic Data Management System (EDMS) for use on the flight deck of transport a

2、ircraft. The EDMS may be the primary, and in some cases sole, on board source of documentation and information for flight operations, engineering, aircraft maintenance, cabin services, and training. This document addresses flight operations applications only. It addresses the requirements for the fl

3、ight deck characteristics of airborne equipment elements for an Electronic Data Management System (EDMS), but not the ground support system requirements. Development of ground support systems for EDMS will be a significant task, which must take account of the end-user information handing requirement

4、s specified here. An Electronic Library System (ELS) is a partial implementation of EDMS, which incorporates only the data storage, retrieval and display functions. The appropriate aspects of this document are applicable to Electronic Library Systems.2. REFERENCES:2.1 Applicable Documents:The follow

13、 operation will be achieved by a system which permits operation of an aircraft without the need for physical transportation of hard copy through the aircraft doors in either direction.PERMANENT DATA: Data which is valid for more than one flight.TEMPORARY DATA: Data which is valid for a single flight

14、.TRANSIENT DATA: Data which is valid for less than a complete flight.3. SYSTEM OBJECTIVES:3.1 EDMS shall be designed with the long-term vision of achieving “paperless“ (fully digital) operation with at least the same total level of safety as is associated with hard copy operation.3.2 EDMS should be

15、capable of a very high degree of flexibility in accepting and presenting customer airline data. Ease of customization to operators individual requirements shall be such as to permit interchange of aircraft between operators on a routine basis. Further information on the requirement for portability o

16、f system characteristics across multiple aircraft types and operators is contained in Appendix A.3.3 There should be no significant extra training associated with the system.SAE ARP4102/15 Revision A- 3 -3.4 The EDMS shall provide all the flexibility of current document based systems. The principles

17、 of classifying operational information described in this document shall be adopted to ensure that the system interface design does not inhibit this essential flexibility.“Paperless“ operation will be achieved by a system which permits operation of an aircraft without the need for physical transport

18、ation of hard copy documentation through the aircraft doors in either direction. The phrase “permits operation“ recognizes that there may be functions for which paper copy is still either desired by the airline, or required by external agencies, notwithstanding the fact that the data may be created

19、or stored in digital form. What specific functions these are shall be entirely determined by the operator and not be limitations imposed by the EDMS. The phrase “in either direction“ recognizes that small but significant items of data are generated on the aircraft itself in the form of reports, logs

20、, etc. The EDMS should accommodate such documents.3.5 Due to the evolutionary nature of EDMS, an interim objective of operation with “Less Paper“ is a necessity. In this evolving continuum, the EDMS should produce: a significant reduction in information support costs on aircraft types on which the s

21、ystem is implemented; no excessive temporary increase in overall information support cost for the airline while operating with a mixed EDMS/paper fleet; a clear upgrade path to paperless operation.“Less Paper“ operation is achieved by a system which requires only the minimum amount of information ac

22、ceptable to the certification authorities concerned to be retained in non-EDMS form. However, operation with more than this minimum non-EDMS or hard copy information shall not be prevented by the system design. It shall be at the discretion of the operator of an EDMS-equipped aircraft to determine h

23、ow much paper over and above the minimum is actually retained.A “Less Paper“ system should be capable of producing both electronic and paper output to meet the requirements of: the airlines Flight Operation Department; other airline departments; external agencies.3.6 The definition of the “minimum i

24、nformation“ shall be undertaken by collaboration between the airframe and equipment vendors, the operator, and the certification authorities. It should take the form of a statement of the information required to operate the aircraft at an adequate level of safety following the in-flight loss of info

25、rmation contained in the EDMS. This shall take into account the circumstances under which the loss of EDMS information might occur, including the operational environment in which the aircraft will be utilized.SAE ARP4102/15 Revision A- 4 -3.7 The medium on which the minimum non-EDMS information is s

26、tored should not be restricted to paper. In considering the acceptability of other media, there should not be a higher requirement for redundancy, accuracy, and integrity than is achieved by current information supply methods.3.8 For “paperless“ operation as described previously, the EDMS shall prov

27、ide the “minimum information“ via either internal or associated external devices which have a reliability adequate to assure the required overall level of safety. The internal or external devices shall remain fully functional under all the circumstances in which the minimum information was determine

28、d to be applicable, e.g., including total loss of aircraft power supplies.4. OPERATIONAL REQUIREMENTS:4.1 General:4.1.1 Whenever the EDMS replaces printed documentation, the information required for the safe conduct of the flight shall be available throughout the flight.4.1.2 The EDMS information sh

29、all be accessible and usable on the aircraft both in flight and on the ground.4.1.3 The EDMS should accommodate connection to ground networks for updating and exchange of data as needed.4.1.4 The EDMS shall allow fast and easy access and shall display only the requested information. Information rela

30、tive to emergency and abnormal procedures shall be available in a time frame not greater than that commensurate with current paper checklists.4.1.5 Operation of the EDMS shall not require any special skills.4.1.6 An EDMS terminal should be provided for each crew member. If a single unit is installed

31、 for the pilots, it shall be accessible to both pilots.4.1.7 The system shall be capable of prioritizing user terminals, with the pilots terminal having the highest priority.4.1.8 The information shown on each pilots EDMS display shall only change in response to action by that pilot. If other system

32、s such as EFIS use information stored on the EDMS, these displays may change as appropriate for the requirements of such systems.SAE ARP4102/15 Revision A- 5 -4.2 Functional Requirements:4.2.1 Reference Information: The EDMS shall contain selected reference information to support the operation of th

33、e aircraft. The information may include but is not limited to:(a) Operating environment requirements and procedures such as:Navigational informationAirport informationATC requirements/proceduresWeather requirements/proceduresRegulatory material, e.g., FAR and A17(b) Aircraft specific information suc

34、h as:LimitationsProceduresMinimum equipment list/CDLPerformanceTechnical log bookSystem schematicsWeight and balance(c) Company and crew specific information such as:Standing orders and proceduresCrew scheduling requirements and informationSecurity proceduresPassenger service proceduresCommercial in

35、formationPassenger listsAirline operating timetables4.2.2 Form Filling: The system shall give the capability to complete any form or report which the operator uses by electronic data entry. The data entry technique employed should not be more time-consuming than use of paper forms.4.3 Data Classific

36、ation:4.3.1 An EDMS intended to meet the objective of Paperless Operation shall be able to accommodate all current paper-recorded data.4.3.2 Data shall be categorized and accommodated in the following terms.SAE ARP4102/15 Revision A- 6 -4.3.2.1 Permanent Data (data which is valid for MORE THAN ONE F

37、LIGHT): This would encompass the vast majority of manuals, charts, etc., and is the data which is generally considered as suitable for Mass Memory Storage.4.3.2.2 Temporary Data (data which is valid FOR A SINGLE FLIGHT): This is a very small percentage of the total data needed for overall operation

38、of the aircraft, but is a very high proportion of the data which is normally used by the crew in day-to-day operation, comprising items such as Flight and Fuel Plans, and briefings such as weather information and NOTAMs. This information is currently provided in the form of paper which is disposed o

39、f at the end of the flight, and is suitable for small media transfer such as 3.5 inch data disk.4.3.2.3 Transient Data (data which is valid for LESS THAN A COMPLETE FLIGHT): Includes weather reports and other information which changes during the course of a flight. This is an extremely small percent

40、age of the total data needed for operation; it is historically accessed via airborne voice communications and would be suitable for transfer via data link.4.4 Information Retrieval Criteria:4.4.1 The method of retrieving data shall be self-evident. The time to search and display requested informatio

41、n should be less than 1 s. The time to print information should be less than 10 s per page.4.4.2 Means shall be provided to retrieve all information related to a specific task, and retain it for later quick and easy use.4.5 Information Retrieval Techniques:4.5.1 In order to achieve the flexibility n

42、eeded by airlines to mix types, equipment sources, and degrees of “Less Paper“ operation, and thus avoid inhibiting the commercial deployment of resources, no EDMS installation should impose fixed and unique requirements on the flight deck users. A set of common information access principles should

43、be used to ensure that the same basic process to find or utilize information always produces the same results.4.5.2 Dependent on pilot background, training, and experience, a crew member may approach an information retrieval task from any one of a number of viewpoints: the information access system

44、shall permit all likely search strategies to be employed. At least the following three strategies (Topic, Task, and Indexed strategies) shall be provided.4.5.3 Topic Access: There shall be access to information through basic categorization into the following fundamental topics:4.5.3.1 Operational En

45、vironment: Includes information on geographic and meteorological characteristics.4.5.3.2 Aircraft: Includes information relevant to the particular aircraft on which the EDMS is installed.SAE ARP4102/15 Revision A- 7 -4.5.3.3 Personnel: Includes information on restrictions on and requirements for emp

46、loyees which are the concern of the airline.4.5.4 Where a subject can be regarded as belonging in more than one of these categories then it must be accessible through all appropriate topics. Suitable techniques such as “hypertext“ shall provide links which enable the crew member to find the correct

47、answer whichever way he or she chooses to approach the problem.4.5.5 While the “Topic“ access concept described previously provides a means of finding any data in the system (analogous to the pilots current ability to open any book and use the index or contents pages, or his/her own acquired knowled

48、ge, to find the information), the system shall provide a facility analogous to the pilots own ability to ignore any data until it is relevant to his/her own particular flight objectives. A technique shall, therefore, be available to provide sorting of data, so that the data relevant to the particula

49、r flight is most readily available.4.5.6 A fourth basic topic in addition to “Environment“, “Aircraft“, and “Personnel“ should, therefore, be a sub-set of data from these three primary data sets, which is sorted information appropriate to the specific flight. This would almost always include, but not be limited to, the data classified as “Temporary“ data, and should be described as “This Flight“ data.4.5.7 Task Oriented Access: A second access technique shall be provided via a task-oriented indexing system. The following four categories of basic task
