Airspace Infringement Working Group

The Airspace Infringement Working Group (AIWG) is a Civil Aviation Authority (CAA) sponsored cross-industry Working Group. Its purpose is to monitor airspace infringement data and identify trends in order to identify, propose and instigate corrective actions in order to significantly reduce the incidence of, and risks associated with, airspace infringements for the benefit of all airspace users. In identifying causal factors and determining corrective actions, AIWG will consider whether airspace design or pilot training and competency are features of the pattern of infringements.

Having considered statistical or other evidence, the AIWG will make recommendations for corrective action to the appropriate regulatory or industry body. It will also act through its membership to alleviate potential problem areas where this is deemed appropriate. Such recommendations may seek regulatory change, or the development of appropriate education and awareness material, and may either be UK-wide, site-specific, or user-specific. Membership includes representatives from:
