No, one property of the route WANTED by Potomac approach is that it not go
through there. Who's wagging the what?


Well, since Potomac approach IS going to get what they WANT, it follows that
what is NEEDED is a route that does not go through Potomac approach.



Whether they are fixed or not is not information readily available to the
pilot (there are plenty of examples of controller boundaries that are not
fixed).


Cite them.



And the pilot =does= need to know what the boundaries are in
order to make an intellegent decision as to whether to go around it or do
something else.


Why doesn't he ask?
