Drone users must follow a number of restrictions when using the gadgets.

In November 2016, the Civil Aviation Authority launched a website to publish a revised code of conduct, labelled the Drone Code.

The rules say the devices must not be flown:

Above 400ft (120m)

Where you cannot see them

Near aircraft, airports or airfields

Within 150ft (50m) of people or property

Over crowds and built-up areas

Within 500ft (150m) horizontally of crowds and built-up areas.
