MODUK DEF STAN 00-972: PART 13 PDF

Scope and Organisational Background

Prior to using any part of this Defence Standard Part 0 should be read which contains Procedures for use, content and definitions. This part 13 provides System Safety and Functional Performance requirements for Master Time Source systems used for Military Air Traffic Services ashore and afloat and including ATS elements of MOD Contractor Airfield and Range Air Control systems. Currently, this scope does not include Air Defence Systems performing ATS functions, ‘Area' Air Traffic performed utilising NATS systems, or Air Traffic Services performed from Airborne platforms. Refer to Part 1 for information on Regulatory Frameworks for all subsequent Parts.

ATS Master Time Sources refer to Time Clock information presented to ATM Systems, rather than Data Clock information required as part of any digital networked ATM System.
