I'm sorry but I fail to see the point in all of these messages about "breaking the law" on the 250kts below 10000' in the UK, when you, ShyTorque, said this a few messages ago:
SNS3Guppy, The reason I asked was because under UK aviation law, you need a written permission to go above 250 kts in Class G airspace. I don't think ATC can give ad hoc permission on the day; Class G doesn't "belong" to ATC.
I trust that SNS3Guppy and his/her 747 spend most of their time during their initial climb in IFR within CAS? Am I wrong?
Ciao, Luca
