The A320 had been descending through 1.700 ft in the "final stages" of its ILS approach to Gatwick's runway 26 on April 28th.

One of its pilots saw a "dark coloured" drone ahead of the aircraft and took "avoiding action" involving 5-8° right bank.

Investigators classified the incident as bearing the highest category of risk.

The drone operator has not been identified by the investigators.
