The CAA has advised pilots to take extra care when flying the Matrice 200

UK police have grounded some drones because of a fault that means they can fall out of the sky, BBC Radio 5 Live has found.

It follows a warning about the devices which, in a few cases, have unexpectedly suffered “complete loss of power during flight”.

Models in the Matrice 200 series are among those used by the police.

DJI said in a statement that it was “thoroughly reviewing” reports of power issues with the products in question.

The problem results “in the aircraft falling directly to the ground”, according to the UK’s Civil Aviation Authority (CAA).

This occurs even though the battery appears to have charge remaining.

“There’s thousands of these specific models around the world being used by police and emergency services who favour its ability to operate in windy and rainy conditions,” Andrew McQuillan, from Crowded Space Drones, told 5 Live’s Phil Williams.

The firm uses the M200 drones for public safety and counter-terrorism, as well as at festivals and football matches.

He said he backed the CAA’s guidance – even though it was impacting his business: “I’ve no issue with that at all because they’re keeping people safe.

“You don’t want drones flying overhead people if they’re going to potentially crash into them, or there’s a higher risk of that.

“And the police don’t want that either.”

UK police forces use drones for various tasks – including thermal image surveys of large building fires

Various police forces confirmed to the BBC that they had grounded the drones.

Derbyshire Police said: “This is for public safety. However, we have other drones that are not affected by the issue and these are still in use.”

Just five days ago, the force published a press release in which it said it was “pleased to announce” that M200 series drones had been added to its fleet after a year of testing.

Devon and Cornwall Police said: “Following the safety notice from the CAA, we have grounded two drones. This has taken our numbers of available units from around 20 down to 18.”

In a policy document available online, it singles out one of the models as a key part of its fleet: “Where possible, the DJI Matrice M210 will be deployed as the primary drone due to the extra capabilities it provides.”

Greater Manchester Police said: “Specially trained drone operators from GMP were trialling the use of the DJI Matrice 210. Following a safety warning from the UK’s Civil Aviation Authority, GMP have grounded the use of this drone as a safety precaution.”

Heads up

While no reports of injuries or damaged property have yet been received by the CAA, it said the drones should not be flown above people “at any height until further notice”.

Flying within 50m (164ft) of people, vessels, vehicles or structures which the pilot is not also in control of, has also been temporarily prohibited.

DJI has advised customers to update the firmware on their aircraft and batteries.

DJI’s more advanced drones are increasingly being used by businesses for tasks like surveying

The Matrice 200 drones are slightly larger than the most common consumer drones and weigh in at around five or six kilograms, depending on what equipment – such as a camera – is being carried.

On its website, DJI claims the models are “built to endure” and explains that they have17in (43cm) propellers.

The Chinese firm continues to develop drones aimed at professional users – such as the new Mavic 2 Enterprise, which has been designed for uses including search and rescue.

Among its features is a 100-decibel loudspeaker that can be used to broadcast pre-recorded messages.

The Mavic 2 and the Matrice 200 are both designed to appeal to commercial clients experimenting with drones for tasks like surveying and site monitoring, said Tom Morrod, an analyst at IHS Markit.

Problems with the Matrice 200 could cause concern in that sector, he pointed out.

“It’s potentially going to slow down a lot of that experimentation, the opportunity to establish new business cases,” he told the BBC.

“Having them not fall out of the sky… is clearly important.”
