Aviation: Drone collision with jet highlights growing danger

Posted

LONDON >> A collision between a British Airways passenger jet and a drone over London has left the plane undamaged but the aviation industry deeply shaken.

British police and air accident authorities were investigating Sunday's incident, in which an Airbus A320 carrying 137 people struck an object believed to be a drone at a height of about 1,700 feet (518 meters) while it was approaching Heathrow Airport.

The plane landed safely and was cleared to fly again after an inspection by engineers. But the incident has focused attention on the growing number of unregulated drones in the sky and the potential for disaster if they hit a plane — either accidentally or on purpose.

London's Metropolitan Police said Monday the incident occurred over Richmond Park, a large open expanse a few miles from the airport. Chief Superintendent Martin Hendry said the incident "highlights the very real dangers of reckless, negligent and sometimes malicious use of drones."

"The potential is there for a major incident," he said.

How many drones are out there?

The authorities don't know exactly, since small drones bought for private use often don't have to be registered, but the market is growing fast as drones become cheaper and easier to operate.

In Britain alone, electronics stores sold thousands during the 2015 Christmas season. Phil Finnegan, director of corporate analysis at aerospace research company Teal Group, estimates there are "several million" drones in the United States.

Tony Tyler, director-general of the International Air Transport Association, told an aviation conference in Denmark on Monday that drones "are here to stay."

"But we must not allow them to become a drag on the efficiency of the airways or a safety threat to commercial aviation," he said.

Tyler called for "a sensible approach to regulation and a pragmatic method of firm enforcement for those who disregard rules and regulations and put others in danger."

What are the rules?

Many countries distinguish between commercial drone operators, which must be licensed, and those used recreationally.

In Britain, operators don't need a license to use a small drone weighing less than 20 kilograms (44 pounds) for recreational purposes.

Drones must not be flown above 400 feet (120 meters), must remain within sight of the operator and must and kept away from planes, helicopters, airports and airfields. Violators can receive six months in prison and a fine — though prosecutions have been rare — but endangering the safety of an aircraft carries a maximum life sentence.

While actual collisions are rare, Britain's Civil Aviation Authority says there were 40 near misses between drones and aircraft in 2015, compared to nine in 2014. In the U.S., the FAA recorded almost 600 incidents of drones getting too close between Aug. 22, 2015 and Jan 31, 2016.
