You also must have a flight plan. It is more than a prerequisite
for the clearance, it is an explicit requirement of the same regulation
that requires the clearance.


Unless otherwise authorized by ATC.


Sorry Steven, incorrect. There is no qualification on the requirement
for the flight plan. What ATC can do is authorize deviations on the
content of an IFR plan. It is in the "Information required" section that
starts with "unless otherwise authroized by ATC." This is what
permits the filing of the "abbreviated" (most places) or TEC
(californicate) plans.


So the regulation does not permit a popup?
