When you write "as per flight plan" do you mean the route as well as the altitudes? If so, what do you do if you get a full-route clearance prior to takeoff? [Edit: for your first item, you mean three minutes after passing the clearance limit? If so, what is the procedure for when the clearance limit is the destination airport?]
I still don't like the time limits. Two or Three minutes is even worse than what was stated to be the procedure in Brazil. What if ATC loses their radios for 10 minutes? Certainly everybody is at an altitude that would maintain separation for 10 minutes. But, if after 3 minutes all airplanes in that sector start changing altitudes, it seems more dangerous to me than just sitting tight on course and altitude.
