You can fly close to uninvolved people but you cannot intentionally overfly them
People flying drones that are between 250g-500g will need to do the Drone and Model Aircraft Registration and Education Service (DMARES) to get their Flyer ID (this is free). Once you have your Flyer ID you will then need to get an A2 Certificate of Competency (A2 CofC) from a certified company such as UAVHUB.
Once you hold an A2 CofC you will be able to fly these drones in areas used for recreational, industrial, residential and commercial purposes. You must always maintain unaided visual line of sight with the drone and you can't intentionally overfly uninvolved people (people who aren't involved with your flight!).
If you choose not to get an A2 CofC, you will need to:
- Do the Drone and Model Aircraft Registration and Education Service and get your Flyer ID
- Stay 150 metres away from congested areas
- Stay a minimum of 50 metres away from uninvolved people
You can also fly commercially with or without the A2 CofC.
Examples of drones in this category are:
- Parrot ANAFI
- DJI Spark
- DJI Mavic Air (1st generation)
