On the 3rd May 2004 at the Civil-Military Interface Standing Committee (CMIC), the Military Authorities of the ECAC Member States have agreed on a voluntary installation programme of ACAS II (TCAS II version 7.0) on military transport-type aircraft by 1 January 2005.
On 25 March 2010 the European Aviation Safety Agency (EASA) launched a regulatory initiative for the introduction of ACAS II software version 7.1. On 20 December 2011, the European Commission published Regulation 1332/2011 of 16/12/2011 mandating the carriage of ACAS II version 7.1 within European Union airspace. As a new version 7.1 of the TCAS II logic was standardised and regulated by EASA, there was a need to update the Policy for Military Aircraft so that safety considerations are addressed.
This issue was discussed at CMIC/48 on 21st April 2016 (CMIC/48 Action Paper #1 dated 25/03/2016). As a follow on, a Draft Revised ACAS Policy for Military Aircraft was prepared by the Agency and discussed at Civil-Military CNS Focus Group (CNS FG) #24 on 28 September 2016. The proposed Policy has a voluntary nature and it simply amends the version of the TCAS logic to be considered (from 7.0 to 7.1 or above).
CNS FG nominees have been invited to submit any final comments by 06/10/2016 (COB). Due to CMIC delays for the submission of action papers, such draft Policy is submitted in parallel to CMIC for endorsement, on the condition that any amendments proposed by CNS FG will be considered in the final version.
