September 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 and for the investigation to be completed.

The MORs processed by the ICG were subject to one or more of the following criteria:

  • 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 registration/callsign
  • Repeat Infringement by pilot-in-command

(*) Warning letters

Pilots who are the subject of airspace infringement MORs that do not meet the criteria of those processed by the ICG are contacted by the CAA to notify them of their potential infringement and to request a pilot report.

Once the investigation is complete, and if an airspace infringement is confirmed, the pilot will be sent a warning letter to close the occurrence.

This action has been in effect since the 1 June 2019.

Airspace infringements: 2018 statistics

Causal factor analysis of airspace infringements

Analysis of airspace infringement reports from 2017 has shown that the correct use of a moving map could have helped avoid 85% of airspace infringements.

Occurrence reports from private pilots were assessed against four key measures that could have helped prevent the infringement or reduced its impact on other air traffic or controllers:

  • Use of moving maps with an airspace warning
  • Use of a frequency monitoring code (FMC), also known as a listening squawk
  • Recognition of/dealing with overload and distraction
  • Better familiarity with aircraft and equipment

The report was carried out by a sub-group of the CAA’s Airspace Infringement Working Group, made up of three experienced General Aviation pilots.
