Flyer ID
The flyer is the person who flies the drone or model aircraft.
You must pass an online theory test to get a flyer ID. The test is free. You should prepare for the test before you take it.
Children under 13
Children under 13 must also pass the test to get a flyer ID. For data protection reasons, they must register with their parent or guardian.
There’s more information in the children and parent guidance.
Operator ID
The operator is the person responsible for managing a drone or model aircraft. This means they’re responsible for things like maintaining it and making sure that anyone who flies it has a flyer ID.
They’re usually the person or organisation that owns the drone or model aircraft, but not always. For example, if you’re younger than 18 and you own a drone or model aircraft, you must ask your parent or guardian to register for an operator ID. You’ll still be able to fly as long as you have a flyer ID.
The operator must:
- make sure that only people with a valid flyer ID use their drone or model aircraft
- label their drones and model aircraft with their operator ID
You must be 18 or over to register for an operator ID. You can use the same operator ID for all your drones and model aircraft.
If you’re responsible for drones or model aircraft, but will not fly them you can register as an operator only.
