Rules for the use of drones by airports could be tightened after a number of near-misses, including one believed to be at London City Airport .

The UK Airprox Board investigated seven near misses in the 12 months to July with the Docklands hub among that number, according to The Times. The paper reports the results could have been " potentially fatal" .

Transport minister Robert Goodwill confirmed that the Government is “aware that there are safety and security issues that need to be addressed” in relation to drones.

In a Parliamentary answer, he said: “The Government is in early discussions with international partners about a drone traffic management system.”

A spokesman for the Civil Aviation Authority said: “Users must understand that when putting a device into the air they are interacting with one of the busiest areas of airspace in the world – a complex system that brings together all manner of aircraft including passenger aeroplanes, military jets, helicopters, gliders, light aircraft and now drones.”

Drone users can be prosecuted under the Air Navigation Order 2009 if they are flown beyond their line of sight, which is measured as 500 metres horizontally and 400ft vertically.
