51. Deconfliction Minima

Question 1

According to MATS 1, when providing a Deconfliction Service, what are the required deconfliction minima against uncoordinated traffic?

Answer 1

The deconfliction minima against uncoordinated traffic are:

1) 5nm laterally (subject to surveillance capability and regulatory approval); or
2) 3000 ft vertically and, unless the SSR code indicates that the Mode C data has been verified, the surveillance returns, however presented, should not merge. (Note: Mode C can be assumed to have been verified if it is associated with a deemed validated Mode A code. The Mode C data of aircraft transponding code 0000 is not to be utilised in assessing deconfliction minima)

Question 2

According to MATS 1, when providing a Deconfliction Service, what are the required deconfliction minima against aircraft that are under the control of the same controller, or that have been subject to coordination?

Answer 2

The deconfliction minima against aircraft that are being provided with an ATS by the same controller, or that have been subject to coordination, are:

1) 3nm laterally (subject to surveillance capability and regulatory approval); or
2) 1000 ft vertically; (2000 ft within active MDA/MTA above FL410, and above FL290 where both aircraft are not RVSM approved); or
3) 500 ft vertically (subject to regulatory approval).
