3、egarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provisional nature because it is an interim draft. A revised version of this document is being produced by IEC/TC 97. It should be applied on this provisional basis, so that information
4、and experience of its practical application may be obtained. Comments arising from the use of this Draft for Development are requested so that UK experience can be reported to the European organization responsible for its conversion into a European Standard. A review of this publication will be init
5、iated 2 years after its publication by the European organization so that a decision can be taken on its status at the end of its three-year life. The commencement of the review period will be notified by an announcement in Update Standards. According to the replies received by the end of the review
6、period, the responsible BSI Committee will decide whether to support the conversion into a European Standard, to extend the life of the prestandard or to withdraw it. Comments should be sent in writing to the Secretary of BSI Technical Committee EPL/97, Lighting and beaconing of aerodromes, at 389 C
7、hiswick High Road, London W4 4AL, giving the document reference and clause number and proposing, where possible, an appropriate revision of the text. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to internati
8、onal publications with their corresponding European publications.

22、 University, Tue Dec 12 07:10:05 GMT+00:00 2006, Uncontrolled Copy, (c) BSI ENV 50230:1997 BSI 04-19993 Introduction The International Civil Aviation Organization (ICAO) in its Annex 14 to the Convention on International Civil Aviation, paragraph 8.2 Electrical Systems and paragraph 8.3 Monitoring,
23、presents provisions, either as international standards or recommended practices, regarding control and monitoring systems for visual aids: “A system of monitoring visual aids should be employed to ensure lighting system reliability. Where lighting systems are used for aircraft control purposes, such
24、 systems should be monitored automatically so as to provide an immediate indication of any fault which may affect the control function. This information should be automatically relayed to the air traffic service unit.” And: “For a precision approach runway, the electrical circuits for the main power
25、 supply, lighting and control shall be so designed that the failure of one circuit shall not leave the pilot without visual guidance or shall result in a misleading pattern.” Different control and monitoring systems of airfield lighting exist nowadays. This is why the need appeared to define their g
26、eneral characteristics or requirements in order to guarantee compatibility between systems. 1 Scope This prestandard specifies general requirements for control and monitoring system of aviation ground lighting installation. The purpose of this prestandard is to provide a set of requirements which ar
27、e applicable to the control and monitoring system of aviation ground lighting installation. 2 Normative references This prestandard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publi
28、cations are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this prestandard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. ENV 50231, Aviatio

35、system for the airfield lighting system should be considered as a part of the visual aids system, and consequently should be addressed like a component of the ATC system. Therefore design and workmanship of such a system should fulfil the high requirements for availability and fail safe operation. B
36、esides keeping the controller workload in a reasonable level, the system should be a powerful tool for the organisation of preventive maintenance to increase the availability of the airfield lighting system. There should be a control and monitoring system: a) Suitable for every airport complexity an
37、d particular needs, and adaptable to changes in the airport physical characteristics (layout, installations, etc.) or in the airport procedures. It means a system designed on a modular basis. b) Having a conception inspired by safety, allowing for the redundancy of equipment or elements that prove c
38、rucial from a safety point of view. c) With a high degree of reliability and availability. d) Capable of data exchange with related systems. These system descriptions contain only the functions and minimum requirements of a control and monitoring system independent from a particular hardware solutio
39、n. The hardware design of a system should follow the individual needs of an airport and should also be in accordance with the latest state of the technology. 5 Overview of the control and monitoring system Figure 1 shows an overview of the control and monitoring system with the peripherals and inter
40、faces to the related systems. In the centre of this diagram the control and monitoring system is placed. Around this circle the operators, components and systems are arranged which are linked to the control and monitoring system. The arrows show the direction and also a short description of the data
41、 flow. Possible or necessary links between the peripherals themselves or to other systems are not subject of this description and are not shown in the diagram. The peripherals for a basic system are: a) Human machine interface (HMI) for the controller. That could be the controller at the tower but a
42、lso controller at the apron control or other controller working positions at the airport, which are able and allowed to switch the airfield lighting system. The HMI provides also the certain relevant status information for the controller. b) HMI for the maintenance staff at the airport. c) Status pr
43、otocol devices such a storage device and or protocol printer or other components that store the time and sequence of alarms and status informations. d) Interface to the CCRs and other control units (for example: sequence flash light control unit, circuit selector, contactor, etc.) but may include de
44、vices that only provide indications (for example: power generator, fuel level indications, etc.). Dependent on the configuration and requirements of an airport the control and monitoring system may provide the additional interfaces as an option: a) Interface for information interchange with airport
45、systems such as aircraft docking systems, building management systems or commercial systems. b) Interface to the ATC-system for command inputs (for example: actual CAT I, II, III information) and information output about the status of the airfield lighting system. c) Interfaces for additional monito
46、ring devices for the supervision of the actual condition of the airfield lighting system components (for example: lamp operation monitoring, insulation measurement, hour meter, etc.). d) Interface for control signals from-field sensors. e) Interface to meteorological system to provide the runway vis
47、ibility range (RVR). f) Interface to a surface movement guidance and control system (SMGCS) for command inputs and information output about the status of the airfield lighting system.

The main objectives for the design for the HMI are to keep the controller workload at a reasonable level and to allow the controller to select a command input and system to provide an accurate status output. To fulfil these requirements the functions of the HMI should provide only the functions and information that
