When switching tracks the normal procedure is that one get an approach limited/medium aspect, followed by a limited/medium clear at interlocking. No problemo so far. However all guides and rules I read says that once clear of interlocking, normal speed applies. NORAC RULE #243: Next Governing Signal also says that you are allowed to operate according to the indication of the next fixed signal once you can see it clear if youre clear of interlockings and not in restricted speed. How can I use these to my benefit when ATC still keep me in Approach limited aspect and CDU show 45mph until I passed next signal. As I understand it I should be allowed to acc up to normal speed (line speed) once clear of interlocking.But how am I supposed to do that when ATC wont let me? Hope you get my point and understand what i wanna know.
