BOAC,
What I think he is raising is that they no longer require to have 'Suitable' airfields, only 'Adequate' ones. They could route north across KEF etc with airfields within 400nm all totally 'out' weather wise quite legally, and be further away from an airfield from where the suitable weather exists.
It would require some extremes of weather across the whole route I appreciate, but the basis of what he suggets could technically happen......
Stupid rule I know, but thats what IS actually allowed
