A2 CofC and Legacy Drones: Transitional Rules in the UK

When the Open Category class-marking system was introduced, a large number of drones were already on the market without a C-class label. These are commonly called "legacy" drones, and they have been governed by transitional arrangements that allow them to keep flying while the new system phases in.

This guide explains how the A2 Certificate of Competency (A2 CofC) relates to legacy drones and why checking the current rules for your specific aircraft matters.

What counts as a legacy drone?

A legacy drone is one that does not display a C0 to C4 class marking. This includes many popular consumer models released before manufacturers began applying class labels. The absence of a class marking does not make a drone illegal, but it does change which subcategory and distances apply.

How the A2 CofC helped with legacy drones

During the transitional period, holding an A2 CofC has allowed pilots of certain legacy drones in particular weight bands to fly closer to uninvolved people than they otherwise could under the open A3 rules. The precise minimum distances for legacy drones have differed from those for a class-marked C2 drone, and they have depended on the drone's weight.

• The lightest legacy drones, under 250 g, are generally treated under the most permissive subcategory regardless of the certificate.
• Heavier legacy drones have benefited from the A2 CofC by gaining reduced separation distances during the transition.

Why the rules keep changing

Transitional arrangements are, by design, temporary. The CAA has revised the end dates and conditions of these arrangements more than once, so any guide can only describe the general principle. The safest approach is to confirm the current transitional position directly from CAA guidance before each significant operation.

Legacy versus C2 class-marked drones

If you are choosing a new drone and want the clearest path to A2 privileges, a C2 class-marked drone removes much of the uncertainty, because the A2 subcategory distances apply directly. With a legacy drone, you depend on transitional rules that will eventually be withdrawn.

Practical steps for legacy drone owners

1. Identify your drone's take-off weight and whether it has any class marking.
2. Register for an Operator ID and a Flyer ID where required.
3. Consider obtaining an A2 CofC if you want reduced distances from people.
4. Check the current CAA transitional guidance before flying close to people.

Because the situation evolves, treat the certificate as one part of a wider compliance picture rather than a permanent guarantee of any specific distance.
