I've read in the Airplane Flying Handbook that the turn into or departing from the pattern should be made past the departure end of the runway within three hundred feet of the pattern altitude. Does that mean both conditions have to be satisfied even in the case of a very long runway? In other words with a long runway a typical GA airplane will be airborne, reach pattern altitude, and will have to level off and wait until past the departure end of the runway before making any turns?
