TCAS Version 7.1 requirement in EU airspace

Important information for Third Country Operators (TCO)

According to Commission Regulation (EU) No 1332/2011 (the 'ACAS II Regulation'), it is important to remind all operators that the EU requires ACAS II version 7.1 ahead of ICAO.

For all aircraft with a maximum take-off mass in excess of 5700kg, the following deadline applies for ACAS II upgrade to version 7.1:

  • 01 March 2012 for airplanes with an initial individual certificate of airworthiness issued after 01 March 2012; and
  • 01 December 2015 for airplanes with an initial individual certificate of airworthiness issued before 01 March 2012

More information can be found on EASA's website  and EUROCONTROL's website.

Following this ACAS II Regulation (and its implementation times ahead of ICAO), non-compliant airplanes may be excluded from TCO Authorisation for operations within EU airspace.

Please be informed that non-compliant aircraft identified during ramp inspections after 01 December 2015 may be subject to immediate enforcement action.
