UK Airprox Data Map

An airprox is a situation where a pilot (or air traffic controller)  considers the distance between two aircraft compromises safety.

The UK Airprox Board has been set up by the Civil Aviation Authority and the Military Aviation Authority with the sole purpose of investigating these ‘near miss’ incidents to improve aviation safety.

Each incident is investigated by the board and they determine one or more causal factors which led to the report being filed. We can learn lessons by looking at the causes so that aviation safety can be improved.

The Airprox Board assigns each incidence with a risk ranging from A to E:

  • A – Risk of Collision: aircraft proximity in which serious risk of collision has existed
  • B – Safety not assured: aircraft proximity in which the safety of the aircraft may have been compromised
  • C – No risk of collision: aircraft proximity in which no risk of collision has existed or risk was averted.
  • D – Risk not determined: aircraft proximity in which insufficient information was available to determine the risk involved, or inconclusive or conflicting evidence precluded such determination
  • E – Met the criteria for reporting but, by analysis, it was determined that normal procedures, safety standards and parameters pertained.

Categories A to D are agreed international and E is only used in the UK.

UK Airprox Map – 2000 to 2018

You can use this map to explore the reports made since the year 2000. To bring up more information about an incident then you just click on it.

The map displays the airprox data for 2017 as default.

You can add (and hide) near miss incidents for other years by clicking the icon in the top left corner. It will bring out a menu where you can click to add layers for the years 2010 to 2018. You can also add all the airprox data from 2000 to 2009 in a single layer.
