What are the safety restrictions placed on drone users?
Drone users have to 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, called 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.
