Airspace infringements: 2017 and 2018 statistics compared


ICG meeting data

Each month the CAA will publish statistical data of infringement Mandatory Occurrence Reports (MORs) processed under CAP1404 by the CAA’s Infringement Coordination Group (ICG).  The IGC is a cross-organisational Regulatory Group comprising members of the CAA and one member of the Military Aviation Authority (MAA); details of composition can be found in CAP1404.

The MORs processed do not correspond numerically to those reported in the same month due to the time taken to collate MOR, Pilot and supporting supplementary reports.  MORs are read by the ICG when one or more of the following exist:

  • Loss of separation
  • Safety Intervention Measures implemented such as (but not exclusive to) avoiding action, radar vectors, cessation of departures, holding etc
  • Repeat Infringement by pilot-in-command

(*) from 1 June 2019, all other pilots subject of airspace infringement MORs are contacted by the CAA to notify them of their airspace infringement and a pilot report requested. Once the investigation is complete, and if an airspace infringement is confirmed, the pilot will be sent a warning letter to close the occurrence.

(**) listed as a separate course of action from June

Causal factor analysis of airspace infringements

Annual reports are produced by a sub-group of the CAA’s Airspace Infringement Working Group, made up of three experienced General Aviation pilots.
