Hundreds of thousands of air passengers face Christmas travel chaos at one of the U.K.鈥檚 busiest airports, one expert says increased drone use in Canada could bring similar misery here.

The runway at London鈥檚 Gatwick Airport has been closed since Wednesday after two drones were spotted in its airspace, believed to have been flown deliberately near the flight path to cause disruption.

Pilots have reported numerous near-misses with drones in recent years in the skies over Canada and aviation authorities have warned there is a growing risk that a midair collision could cause a major disaster.

Sterling Cripps runs Canadian Unmanned in Medicine Hat, Alta., where he trains commercial and government users on how to legally and safely operate drones.

He estimated aircraft were involved in around 500 near-misses involving drones this year.

鈥淚f you鈥檙e a pilot and you happen to see an object fly by and you can identify it as a drone, it鈥檚 deadly close,鈥 Cripps, who is also a commercial pilot, told CTVNews.ca. 鈥淭his is a real danger for us.鈥

Canada has tougher restrictions than Britain around drone flights near airports, with a 5.6-kilometre exclusion zone here, compared to one kilometre in England. Breaking Canada鈥檚 drone laws and putting an aircraft at risk carries a $25,000 fine or jail time.

People flying illegally in Canada are usually young adolescent males flying for fun, Cripps said.

鈥淚t can be very difficult to identify where the drone is coming from,鈥 he said.

 

 

Proposed updates to the laws around larger drones in Canada are due to come into force in January. Changes include requirements for a basic or advanced pilot permit and registering the machine with a Transport Canada identification number.

A breach of the safety rules, which includes flying above 90 metres and at least 30 metres from vehicles and people, means a possible $3,000 fine.

Cripps said Transport Canada could do even more to advertise .

鈥淭here鈥檚 no excuse for ignorance anymore,鈥 he said.

鈥淯ntil someone is killed or a plane is brought down, I don鈥檛 know if people will become aware.鈥

In October a drone pilot was fined and grounded for three years after he flew his device too close to incoming aircraft at Yellowknife airport.

And in August a Westjet flight came close to disaster after a drone was spotted by a pilot off the plane鈥檚 left wing, 4,000 feet over Edmonton.

This summer, firefighters battling wildfires in B.C. warned drone operators to keep their craft out of the air when fire crews are working, after an unauthorized drone flight forced the grounding of a helicopter.

Civilian drones have grown popular as their price has fallen and have been a popular Christmas gift in recent years.

Technological improvement has meant components are smaller, faster and cheaper than ever.

Police have reminded new drone owners about their responsibilities after a drone was found on the roof of a house in Quebec last July with dead batteries.

Aviation analyst Phyl Durdey told CTV News Channel drones pose a very serious threat.

鈥淲hen an aircraft is on approach they鈥檙e doing about 150 miles per hour (about 240 km/h) and if you have an impact with an object that is two or three kilos in weight that can go through the windshield and hurt the pilots and significantly damage the aircraft,鈥 Durdey said.

He suggested scrambling the signal to bring down the Gatwick drones.

鈥淪ome drones can be remotely operated from three kilometres away and some can be pre-programmed with GPS co-ordinates so you don鈥檛 even need an operator on the ground,鈥 Durdey said.

鈥淚t very hard to protect. The rules are tight, the fines are tight, the jail time is there, so that鈥檚 all they can do right now.鈥

Rules for flying recreational drones in Canada

Fly your drone:

鈥 at least 5.6 km away from aerodromes (any airport, seaplane base or area where aircraft take off and land)

鈥 below 90 m above the ground

鈥 within 500 m of the operator

鈥 within your sight at all times

鈥 at least 30 m away from vehicles, vessels and the public (at least 76 m if your drone weighs over 1 kg and up to 35 kg)

鈥 at least 1.9 km away from heliports

鈥 outside of controlled or restricted airspace

鈥 at least 9 km away from a natural hazard or disaster area

鈥 away from areas where its use could interfere with police or first responders
