There are height limits in place to ensure that drones are used safely. Drones are restricted from flying above 400 feet (122 metres) and within 1 kilometre of airport boundaries. Also, owners of drones weighing 250 grams or more are required to register with the Civil Aviation Authority with drone pilots having to take an online safety test. These requirements come into force on 30th November 2019. If drone users flout the new height and airport boundary restrictions, they could be charged with recklessly or negligently acting in a manner likely to endanger an aircraft or any person in an aircraft which could result in an unlimited fine, up to 5 years in prison or both. Failure to register or sit the competency tests could result in users being fined up to £1,000.00.
