MODUK - DEF STAN 00-972
Military Air Traffic Services Equipment Safety and Performance Standards (Aerodrome, Terminal and Naval Air Traffic Services)
|Publication Date:||14 September 2019|
This Defence Standard provides Acceptable Means of Compliance and Guidance Material, together with definitions of the terms used throughout this document. Specific technical definitions may be separately defined as they are used.
The material contained in all parts of this Def Stan set out the requirements for System Safety and Functional Performance of Military ATS Systems. All equipment that has the capability to be used for ATS or ATM, shall comply with all the appropriate requirements within this Def Stan for the full coverage area, hardware and software used when in this mode regardless of the location of the equipment, platform it is situated on or the operational context in which it is being used. Application of the appropriate contents within this Def Stan shall be made at the time of any significant change to an ATS System Design or Architecture1. The scope of the contents of this Def Stan covers Safety, Performance and Regulatory aspects.
The legal framework for regulatory powers of the MAA is vested in the Secretary of State, with specific exclusions stated in both European Unions (EU) Regulations and the UK Air Navigation Order (ANO). Consequently, provisions within International Civil Aviation Organization (ICAO), EU and UK ANO Regulation are not directly legally applicable to Military ATS Systems, although Military ATS Systems should be demonstrably at least equivalent in Safety and Performance.
'SofS' instruction to Defence is that Health, Safety and Environment Protection (HS&EP) policy statement requires that "….where Defence has exemptions, derogations or dis-applications from HS&EP legislation, we maintain Departmental arrangements that produce outcomes that are, so far as reasonably practicable, at least as good as those required by UK legislation"2. Military ATS Systems are regulated by the MAA.
The purpose of all chapters of this Def Stan is to define Military ATS Equipment System Safety and Performance Standards to providers of Military ATS.
Military ATS providers are expected to demonstrate compliance with applicable requirements either directly or through the provision of Safety Assurance documentation (Safety Case) to the MAA and Military Aviation Duty Holder chain.
Where an ATS provider in support of application for approval submits material produced by a third party (and equipment manufacturer for example), the provider must endorse the content.
This Defence Standard is for regulation and enabling assurance of equipment listed in CAP 670 Appendix A to Part A: Schedule of Equipment to be Regulated under the ANO Articles 205 and 206. To provide guidance on the stement in this Appendix "Any other specific item or class of equipment/system deemed to be safety-related and used to support the provision of an air traffic service. These items or classes of equipment/system are to be promulgated in CAP 670." DT's and equipment providers are to engage with the MAA to seek advice of if the equipment is in or out of scope regarding assurance activities.
