The latest report from the UK Airprox Board (UKAB) shows an improvement during the first six months of 2010 in the most serious airprox incidents involving commercial air transport aircraft, with no reported events at all concerning passenger airlines in the highest risk categories. There had been one category B incident during the first six months of 2009.
There was, however, a small overall increase in reported airprox incidents between January-June 2010 compared to the same period the year before. There were a total of 79 incidents in the first half of 2010 involving commercial, military and general aviation aircraft, in contrast to 60 during January to June 2009.
General aviation aircraft were involved in ten more incidents than in the same period the year before – 44 compared to 34. These included two category A incidents, an increase on the single category A incident during the same period in 2009.
Today’s report shows that the causes of airprox incidents remain predominantly late sightings and non-sightings of aircraft by pilots. The majority of these occur in Class G (uncontrolled) airspace where pilots have the responsibility to see and avoid other aircraft.
