Dick Smith you will of course be able to cite where in the FAA AIM it states that one is allowed to enter class e airspace under IFR without a clearance. Except I don’t know where you got that idea. It is for that reason one gets a clearance void time on every single IFR departure from an uncontrolled airport. You cannot enter controlled airspace IFR without a clearance. You are confused. In the states you can enter class e vfr without a clearance, not IFR. The end.
