Hawk37 Insomniac, quite often the next atc section gives me the next 2, or even 3, waypoints to proceed to. And sometimes they are not flight plan route. So....that's how else I proceed to my destination.
If you read my post you would see I said unless they give you some amendment
anyway if the next atcu gives u other waypoints then thats good and well and as long as you acknowledge the clearance then you would follow it but in case of a radio failure even the next atcu will expect you to follow what u have filed unless you acknowledge any other clearance enroute.
