According to the CAA, the new rules are designed to be easier to understand, as well as allow for “safe expansion” of drones across the UK.
Its requirements also apply to children, but vary for different age groups.
Children under the age of 13 must obtain a Flyer ID and have a parent or guardian present when completing the free flyer theory test to get one.
Meanwhile those aged 12 or younger must be supervised by someone over 16 to fly drones, with parents also required to obtain an Operator ID.
The CAA also wants existing drone owners and ID holders to acquaint themselves with the rules, which sets out where drones should not be flown and how to protect peoples’ privacy when piloting those equipped with cameras.
It says flying a drone or model aircraft without necessary IDs is against the law, and punishable by fines or, in severe cases, with prison sentences.
But Dr Alan McKenna, a law lecturer at the University of Kent, said effective enforcement would likely be “a case of resources”.
He told the BBC while he believed most people would seek to abide by new UK requirements for flying drones outdoors, some may look to “fly under the radar”.
“You’re always going to get people who make mistakes or can’t be bothered,” Dr McKenna said – adding concerns about the impact of rising drone use on the environment, privacy and safety were “wider issues” at play.
