Although I don't know who Woss.... is, there is a paranoid side of me that is thinking that it is I who am being targetted by this thread, as I departed Biggin in exactly that METAR yesterday.
I would agree with much of what has been said, pointing out that I have an IR, the aircraft is a de-iced twin (though the freezing level yesterday was 4000'), there is an IAP and ATC at Biggin and that the weather at Farnborough was suitable for vanilla PPL VFR.
Keef is quite right (he knows me well) that the motivation for departing VFR is to avoiding route charges. I am perfectly happy to pay charges in a controlled environment (such as airways) (though I still don't understand why I, in my Aztec, should and a Seneca, or indeed Arrow, shouldn't) but I am damned if I will willingly pay for a service outside regulated airspace which is voluntary and sporadic.
