Another option is to contact the flying club if there is one on the base.
which you can find out at
www.raffca.org. There is certainly one at Cosford - I had a chat to them at the airshow.
Watch out if you have an old Benson ILS plate - the frequency and ident changed about a year ago. I
think the minima &c are the same but don't take my word for it.
