Investigation After Gatwick Plane Involved In 'Near Miss' on April 25th found air traffic controller not scanning his radar display properly and the time between take off was reduced from 2 minutes to 45 seconds
An official investigation has found a passenger plane taking off from Gatwick airport was involved in a possible "near miss" with another aircraft.
Investigators say what happened back on April the 25th around 1714 in the afternoon was caused by an air traffic controller at Swanwick not scanning his radar display properly.
The time between take off's was reduced from two minutes to 45 secs which was also noted as a factor.
but the UK Airprox Board report say the controller and pilots took hold of the situation so any collision was unlikely.
An Airprox was reported when A319(A) and A319(B) flew into proximity at 1714 on Monday 25th April
2016. Both pilots were under IFR, in receipt of a Radar Control Service from Swanwick.
Airprox 2016071 6 had departed from Gatwick, A319(B) ahead of A319(A). Co-ordination took place with Swanwick for
the Aerodrome controller to vertically separate the two flights following a reduced separation take-off sequence. Both aircraft were transferred to their respective Swanwick Sectors appropriately vertically separated. Unfortunately, separation was lost when A319(A) was then cleared to climb on contact with TC SW Departures before lateral separation had been provided from A319(B). As a result,
A319(A) closed on A319(B) and was given avoiding action by ATC. Minimum separation was recorded as 700ft vertically and 1.9nm horizontally.
The Board assessed that timely and effective actions had nonetheless been taken by the controller; additionally, the rate of catch-up between the two aircraft was very low and the pilot of A319(A) had been aware of the presence of A319(B) ahead so would not have continued on a collision path as a result.
