No doubt that is the case for light aircraft. But, not necessarily so for
jets. For many years the AIM said procedure turn entry and maneuvers could be
done as high as 250 knots, IAS. When it was demonstrated to them that loss of
containment could occur in the entry area at certain angles and adverse tail
wind components, they dropped the max speed to 200.
