Hummingfrog ......of course you are right . I went slightly over the top with that point and accept your criticism . Re read it to be 200 m which gets rid of recirc problem .....my point was solely to point out that you should treat the white stuff as being solid ....you can go around it or under it ....i dont think that is too complicated or contentious ? I think you cannot legislate for this .....i chose to fly INTO it at a very early stage ( with CF11 ) both in single and ME and it was invaluable training . I shall chose to do the same with my son when he finishes his licence ....he will go straight in and realise that it is not a good place to be . Each to his own .
