Definitions Access to recorded material: By access to recorded material is meant a possibility to learn about the information contained in the material by means of the recording media or by availability of printouts, copies or the like of the recorded material. Fixed medium: A recording medium which is integrated/built in some recording equipment, e.g. a hard disk. Mean Time Between Failure - MTBF: The actual operative period of the equipment divided by the total number of errors which have resulted in a discontinuance of the automatic recording, in the equipment during the operative period. Note 1: The duration of the operative period shall be chosen so that it can include at least five errors and preferably more, so that it is possible to deduce a realistic MTBF figure. Note 2: External errors, as for instance power cuts, are not included in the MTBF of the recording equipment. Recorded material: By recorded material is meant recorded voice communication and data that are stored in a fixed medium or a removable medium, as well as print-outs of the recorded material. Removable medium: A recording medium which is not an integrated/built-in part of a recording equipment, e.g. magnetic tape, DAT (Digital Audio Tape), DVD (Digital Versatile Disc), etc. Third parties: By third parties is meant anybody else than the personnel responsible for the recording and the recording equipment. 3. Applicability This BL is applicable within Danish territory and within areas where Denmark according to international agreements is obliged to provide air traffic services. 4. General It rests with the person who has been granted permission to establish and operate a public aerodrome, or with the person who has been granted permission to provide air traffic services outside an aerodrome, hereinafter referred to as the licence holder, and where requirements for automatic recording of voice communication and data have been laid down in pursuance of other regulations, to ensure that recordings and access to the recorded material are made in accordance with the provisions of this BL. Note: Requirements have been stipulated in BL 7-21 on the nature of the voice communication and data that shall be recorded. 5. Recording equipment 5.1 The equipment to be used for automatic recording of voice communication and data, cf. Part 4, shall be approved by the Civil Aviation Administration - Denmark and shall be organised in such a way that the complete content of information can be reproduced (printed out and/or listened to/presented) with adequate sharpness when played back, cf. however, paragraph 5.2. 5.1.1 As documentation for meeting the technical specifications in this BL, analysis may be used and tests may be made for equipment that is legally manufactured and marketed in other EU or EEC member states. 5.2 The requirement for approval according to paragraph 5.1 does not apply to BL 7-23 / Edition 1 / 24.6.2003 / 2
equipment approved by the competent authority of another EU or EEC member state if such approval is based on the standards and recommendations of ICAO Annex 10 and 11. 5.3 The recording equipment must be of a stability corresponding to an MTBF of at least 8000 hours. This value may, if necessary, be ensured by an appropriate degree of redundancy, for instance by duplicating the medium. 5.4 The recording equipment shall be organised in such a way that unintentional erasing cannot take place. 5.5 The recording equipment shall be connected to an alternative power supply (back-up power unit) in the same way as the communication and data units that are recorded. 5.6 Indication of time shall be in UTC and shall be recorded automatically. 5.6.1 The accuracy of the time indication shall be maximum ± 1 second. 5.7 The recording equipment shall be installed and placed so that unauthorised persons have no access to the equipment. 5.8 The recording equipment shall be equipped with acoustic and visual alarms, which begin functioning in the event of irregularities of the equipment, causing lack of recording. Furthermore, the alarm shall begin to function in an appropriate period of time before the recording capacity is spent. 5.8.1 The alarms shall have been taken to a room that is manned when recording takes place. 5.9 The recording equipment shall be included in the unit's/aerodrome's quality assurance system, cf. BL 3-18, and procedures for operation and maintenance shall be available ensuring that the equipment is regularly inspected for correct operation. 5.10 A list shall be kept of the persons responsible for the recording and recording equipment. 5.11 A log shall be kept stating which thirdparty authorities, persons or enterprises, etc. have had access to the recorded material in pursuance of paragraph 7.1, including indication of time, channel number and what was made. 5.12 The recording equipment shall be organised so that it is possible for a person affected by the recording to hear the latest 30 minutes of his own recorded conversation again. 6. Storage 6.1 Recorded material shall be safely stored for at least 30 days, if appropriate, in a medium independent of the recording equipment (e.g. server, magnetic tape, DAT, DVD or the like) until erasing can take place, cf., however, paragraph 6.2. 6.2 In cases where, in pursuance of paragraph 7.1, access to recorded material has been given in connection with preparation of a transcript, the recorded must not be erased without permission from the relevant requesting authority, cf. paragraph 7.2. 6.3 It shall be possible to identify unambiguously all communication and data sequences. 6.4 If the recorded material is stored in a removable medium, such medium shall be identifiable, and records shall be kept of media being used and used indicating time of beginning and end. 7.
