The latest Airprox Insight from the UK Airprox Board looks at an airprox involving a Cabri and a Cessna 152 operating in the visual circuit at Leicester.
This edition discusses the effect marginal weather conditions can have on intended flight profiles, and offers some considerations for pre-flight planning and in-flight decision making with respect to current and forecast weather conditions, including when operating from or to an aerodrome that does not issue its own TAFs and METARs.

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 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.
