December UKAB INSIGHT newsletter now available
The December edition of INSIGHT looks at an Airprox involving a formation of Hawks and a model jet aircraft. The article highlights the fact that not all model aircraft flying sites are published in the UK AIP and, those that are, do not necessarily describe the size of model that could be encountered nor the heights to which they are authorised to operate. Furthermore, none of these model aircraft flying sites are marked on the CAA Visual Flight Rules (VFR) aeronautical charts.

The October edition of INSIGHT looks at an Airprox involving an untraced motor-glider and a DA42 on an instrument approach to Oxford.

The UKAB Annual report 2020
The UK Airprox Board’s new annual report offers an historic overview of cases followed by a detailed breakdown of Airprox by sector, risk, altitude and airspace. Understanding Airprox and the factors behind them is a key step towards mitigating against mid-air collision and UKAB’s sole purpose is to share its work far and wide to strengthen air safety for all. The bulk of the report concentrates on the performance of safety barriers, their associated contributory factors and their interdependencies which, in turn, allows the Board to make informed observations and to identify mitigations which can be employed to improve them.
