A ruling from the office of the FAA Chief Counsel
explaining that the FAA permits
stalls, steep turns, and some ``unusual attitudes'' within
Federal Airways. This is important because (a) it would not
have been obvious from a plain reading of the regulations, and (b)
in many places in the US, including places where a great many
pilots live and train, practically all of the airspace lies
within Federal Airways.
I wish they would change the wording of the regulation to make this
clear, but until then, everybody will have to rely on this FAA ruling.
