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 number of MORs processed each month do not correspond numerically to those reported in the same month due to the time taken to collate MOR, Pilot and supporting supplementary reports.

(*) 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.

Causal factor analysis of airspace infringements

Annual reports are produced by a sub-group of the Civil Aviation Authority’s Airspace
Infringement Working Group (AIWG). The group currently includes three people, all independent of the UK
Civil Aviation Authority: two industry experts whose experience covers microlight flying
and instruction, higher performance commercial and IFR flying and instruction alongside a
third member with experience in SEP flying and PhD level work in causal factors.
