Righto Gentlemen,
I found all the info I wanted, freely available on Her Majesty's government website no less. Now fancy that, allowing mere mortals to see the regulations. Reminds me of the young ****** who told me that that Instrument approach plates were 'restricted material", in Oz.
BTW, Klimax and RAFAT, you two are complete pratts, remind me of the Lord Flasheart episode of Black Adder.
