Many in the UK who unwrapped a new drone this Christmas may face a rude awakening next week, when they will have to take a theory test before being allowed to fly outdoors. From 1 January, those intending to fly drones or model aircraft weighing 100g or more outside must complete a Civil Aviation Authority (CCA) online theory test to get a Flyer ID - something previously only needed for heavier drones. The regulator believes up to half a million people in the UK may be impacted by its new requirements. CAA spokesperson Jonathan Nicholson said with drones becoming a common Christmas present it was important people knew how to comply with the law. With the new drone rules coming into force this week, all drone users must register, get a Flyer ID and follow the regulations, he said.
