Hi
Caledonian and welcome. We may not know the answers here, but that does not stop some of us from replying, & on the whole we do not bite.
Firstly could you clarify your question please?
Are you considering a basic flying school for JAA PPL/IMC/Night, as under JAA-speak that would be a Registered Facility (RF).
Or do you which to start something for more advanced training such as M/E, IR, CPL etc, which under JAA, DOES require a Flight Training Organisation (FTO).
I only ask, as it is relatively easy to set up a RF, but requires a lot more hassle, paperwork & red tape to set up a FTO.
