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.
I think biggin only bills folks if they are taking instrument approaches for training purposes. If you are an arriving IFR flight talking to thames then I'd be suprised if you are charged.
I havent heard of any weather minimums for ILS approachs.
Could be wrong though
