Use the Force,
Maybe on Tatooine you need to file a flight plan for Class D
, but here we have no imperials (with Atlas control gone) so a radio call (which technically is a flight plan, too) will do. And that call would be nearly identical to a call for traffic service.
But there is no assurance that a clearance for airwork in class D will be given, and hence it will make that bit of airspace unsuitable.
Mad_jock,
I agree my students should not pay. They don't - with a bit of notice, I can arrange the general "working" direction to suit both. And Southend also is asking nicely for coordination, and are not ordering me around. If I don't like what they ask for (last week they wanted me to stay below 2,000ft when I wanted to teach stalling) I say so and offer an alternative (in that case, remaining west of a point).
It is all voluntary. I had some cases of attempts to give me instructions in class G (not as nasty as some if the examples in this thread), none of them at Southend.
