The point that I am making is this.. How can the CAA (nats or whoever) impose new airspace IF the date does not correspond with the issue of a chart?
Surely any busts cannot be policed untill the information is in the hands of the pilots?
Why does it need to correspond with the issue of a chart?
There are no new lines to be drawn, it's the area below existing airspace. There has been a fair bit of publicity during the change proposal and there has been an AIC promulgated and there's also a long term NOTAM.
What more do you want?
Are you saying that private pilots are so 'unprofessional' that they can't be trusted to note such changes from those sources? Hang on, there may be a point there...
