This is the Home Page of the UK Airprox Board (UKAB) website. It contains general information and an overview of site content.

The UK Airprox Board’s primary objective is to enhance air safety in the UK, in particular in respect of lessons to be learned and applied from Airprox occurrences reported within UK airspace.

To emphasise both the scope of its work and its independence, UKAB is sponsored jointly, and funded equally, by the UK Civil Aviation Authority (CAA) and the UK Military Aviation Authority (MAA).

The sole objective of the UK Airprox Board is to assess reported Airprox in the interests of enhancing air safety.  It is not the purpose of the Board to apportion blame or liability.  To encourage an open and honest reporting environment, names of companies and individuals are not published in UKAB's reports.

An information factsheet that provides an overview about the UKAB is available here.

Our Website

Our website is intended to contribute to the UK’s continuing drive to enhance air safety.  Details of specific Airprox events are provided together with ‘lessons identified’ and action flowing from UKAB Safety Recommendations.  Our publications can be accessed through this site: subject to our copyright notice, please use these for flight safety purposes.  We also use our website to provide general background information regarding UKAB and its activities.

Definition of an Airprox

An Airprox is a situation in which, in the opinion of a pilot or air traffic services personnel, the distance between aircraft as well as their relative positions and speed have been such that the safety of the aircraft involved may have been compromised.

(ICAO Doc 4444: PANS-ATM).

What are the benefits to flight safety from the UK’s Airprox system?

The most immediate benefit accrues to those involved in each Airprox event.  Pilots and controllers each receive their own full copy of the Board's final report which sets out what happened and why.  Final reports are disidentified to encourage open and honest reporting.  All language of blame is avoided and instead, straightforward statements are made on what took place with the emphasis placed on identifying lessons of benefit to all.  Safety Recommendations are made where appropriate, aimed at reducing the risk of recurrence of a particular Airprox.

Once a year, the UKAB's findings are compiled and an analysis of UK Airprox numbers, rates and trends is produced and published on our website.  All reports are also available individually on this website.  The aim is to raise awareness and understanding by sharing widely the unfortunate experiences of the few for the benefit of the many.

            The sole objective of all these elements is to promote tangible improvements in air safety.
