VFR, getting radar advisories. When not in special use airspace, I suspect I am not obligated to inform ATC of altitude change or modified route--although I would always do so as a courtesy. But what about these circumstances? Is there a requirement to inform ATC or to follow ATC vectors etc, or is it just a matter of courtesy?
1) Flying in special airspace (with clearance), e.g. class B over a major airport?
2) Flying OVER special airspace, e.g. above class B or C?
For example, flying near or over special use airspace, but not in it, ATC says "advise of any altitude change". Does the "contract" implied by my request for radar service, and ATC's agreement to provide, obligate me to follow that directive? Or is it still officially just a matter of courtesy?
I would never ask for a free service, which ATC is not obligated to provide, then not follow ATC requests (barring emergency, or course). But I'm curious about the legalities.
Thanks-- Hunter
