Following a near-miss between a Wiltshire Air Ambulance helicopter and a drone earlier this year, the charity has been reminding people of the dangers of drones.

A drone nearly collided with the service's Bell 429 helicopter as it was lifting from the Recreation Ground.

The charity said: "It was only through the vigilance of the front seat critical care paramedic and the pilot that a collision was avoided."

The air ambulance has experienced drone-related incidents multiple times this year, which have caused delays in departures.

Richard Miller, Wiltshire Air Ambulance’s safety manager, said: "We want drone users to have fun with their drones but to do so safely and legally.

“However, if a drone was to strike a helicopter it is likely to cause significant damage due to the solid metal parts it has and a solid battery.

“We want drone users to help us to ensure our team and lifesaving operation isn’t put at unnecessary risk.”

While drones which weigh less than 250g and do not have cameras do not need to be registered, most drone users in the UK are now required by law to register themselves as a drone operator.

Failure to do so could, which costs £10.33 annually, could result in a £1,000 fine.

If the drone is heavier than 250g, the individual pilot also needs to be registered and pass an exam.

The Civil Aviation Authority has published 'The Drone Code' to ensure safe flying practices.

The code includes regulations such as not flying drones above 400 feet, always keeping drones within direct sight and not flying them near airfields or airbases.

Failure to stick to these regulations could result in criminal prosecution.

Drone users are also advised to be aware of their drones when flying, especially in residential areas where the air ambulance commonly operates.

If the drone operator notices a helicopter, they should land their drone immediately.

Wiltshire Air Ambulance said: "We are not trying to stop people flying their drones but we want them to do so responsibly and safely."

In addition to the regulations, drone users can use the app Drone Assist to issue and review notice to airmen, as well as no-fly zone notifications, ground hazards and the latest map data.

Mr Miller added: "The app is free to download and is a must-have for drone users.

"It is billed as the one-stop shop to help drone users pre-plan flights and to operate safely."
