The ANO contains no definition of a Flying Club! If it did it would be in Article 255 Interpretation.
If you look at the privileges of a Flight Instructor ANO Sched 7 you will see that all instruction has to be given in a club of which both parties are members. That poses an interesting question regarding all the approved FTOs which are not flying clubs and the CAA's own examiners who are not members of clubs, so in essence they all act illegally. Fortunately, with no legal definition, a club is anything you want it to be, i.e. two persons with common interest will do.
I doubt the CAA are keen to define "club" anytime soon, not only because so many establishments would be outside it but also because of this thing called the "internet"
