what must you do if you’re responsible for several drones or model aircraft that require an operator id?

If you’re responsible for several drones or model aircraft that all require an operator ID, you must label every drone or model aircraft you’re responsible for with the same operator ID , not different ones for each.

Core rule

• The operator ID belongs to the responsible person or organisation, not to an individual drone.

• Because of that, you use that single operator ID on all drones or model aircraft you’re responsible for, so they’re all clearly linked back to you as the operator.

What this looks like in practice

• Get (or renew) your operator ID through the relevant aviation authority if your drones/model aircraft meet the registration rules (for example, weight thresholds or having a camera).

• Mark each drone/model aircraft so the operator ID is clearly visible or accessible (for example, on the body shell or in an easily opened battery compartment) and make sure the same code appears on each aircraft you’re responsible for.

Why the same operator ID?

• Using the same operator ID on all your drones makes it easy for authorities to identify who is legally responsible if there’s an incident or rule breach.

• It also avoids confusion with flyer IDs, which are about pilot competence; flyer IDs are not what you put on the aircraft for operator identification in this context.

TL;DR: One operator ID, many drones—put that same operator ID on every drone or model aircraft you’re responsible for.
