Depending on your operational requirements, you can take an A2 CofC or a GVC course.

A2 CofC drone training is for drone pilots flying in the Open category.

Operators wanting to fly in the Specific category (geared at the majority of enterprise pilots) will require an Operational Authorisation (which replaced the PfCO). For this, a GVC is required.
