Any airspace change proposed will comply with the CAA Airspace Change Process described in CAP 1616 and airline operators should expect a requirement for them to be equipped and certificated to operate to defined navigation performance standards.

Equipage by airline operators is covered through notification of required navigation performance in defined airspace volumes and is supported by Articles 116 and 135 of the Air Navigation Order 2016 and in UK (EU) Regulation Part–AUR and Part-OPS as described below:

  • the Annex to UK Regulation (EU) No 923/2012 and in particular point 5015(a) thereof, Annex III to UK Regulation (EU) No 965/2012 and in particular point ORO.GEN.110(d) thereof, Article 59 of UK Regulation (EU) 2018/1139, as implemented by Annex I to UK Regulation (EU) No 452/2014, and in particular point TCO.205 thereof, require that aircraft be equipped and flight crew be suitably qualified to operate on the intended route or procedure. Those requirements should be complemented by common airspace usage requirements specifying the corresponding flight procedures and routes.
  • UK Regulation (EU) No 923/2012 of 26 September 2012 laying down the common rules of the air and operational provisions regarding services and procedures in air navigation.
  • UK Regulation (EU) No 965/2012 of 5 October 2012 laying down technical requirements and administrative procedures related to air operations pursuant to UK Regulation (EU) 2018/1139.
  • UK Regulation (EU) No 452/2014 of 29 April 2014 laying down technical requirements and administrative procedures related to air operations of third country operators pursuant to UK Regulation (EU) 2018/1139.

This information should be considered alongside the 'Policy for the Application of Performance-based Navigation in UK/Irish Airspace', where further policy information and background material has been described.
