What a load of nonsense . How do I know what degrees it is !! I think you will find that for legal purposes VFR day stops 30 mins after the stated sunset in your area . Maybe I am wrong ....
hardly nonsense Nigel, even if you are from Yorkshire - simply the definition of the events which happen at the end of every day. The 30 mins you refer to equates to the period between sunset and the end of civil twilight.
