I'm putting this in the controller area although an answer fro anyone would be appreciated.
I'm looking for a real world example of a situation in which a pilot, particularly a light GA pilot might be asked to intercept a course or radial. Soley to explain what I am getting at, suppose the clearance from MVY begins with V374 GON (which is off the pic). The aircraft takes off on runway 6 and is vectored. At some point instead of a heading to join V374 or an instruction to proceed direct to some waypoint, the instruction is to fly heading 310 intercept the 340 course to FALMA. I can do that, but want something real.
