The aim of this consultation is to seek stakeholder’s views on the publication of the existing St Athan Instrument Landing System (ILS) procedures, previously published in the publicly available Military Aeronautical Information Publication (Mil AIP), into its civilian counterpart, the UK (Aeronautical Information Publication) AIP.

There are no physical or operational changes to the ILS procedures as a result of them being published in the UK AIP, therefore the following elements are out of scope of this consultation: 

  • The path over the ground which aircraft fly;
  • The slope down which aircraft descend to reach the runway;
  • The number of aircraft that would use the procedure;
  • The type of aircraft that would use the procedure;
  • Any of the supporting Air Traffic Control (ATC) procedures;
  • The size, dimensions or classification of any surrounding airspace.

This consultation is concerned only with the publication of the existing ILS flight procedures in the UK AIP.

The map below shows an illustrative rectangle within which the ILS procedures are contained; there is no change to the airspace in the region.
