On that point, Biggin-Hill's new idea appears to be that unless the weather conditions are below certain minima, they will charge £50 + VAT for an instrument approach.
I understand them wanting to discourage training approaches getting in the way of priority inbound IFR traffic, but it where the a/c I fly is based, and there are weather conditions when I would wish to shoot a vectored ILS rather than grope about in 'VMC'.
I am only an amateur, but INHO their approach does nothing for improving safety, apart from being a ripoff.
