Actually, if an OTS event is run to the 1951 rulebook, the book states "each maneuver should be preceded by at least one full lap of normal level flight." Most do two as they are used to doing it this way. Another enigma in these goofy rules is which laps are to be judged for level flight?? The take off and level flight are described as two separate maneuvers so one would think there should be at least one level lap between the take off and the two judged laps, however, again most like to do two so does one run six level laps between takeoff and the climb??. Many contests judge the two maneuvers like the PA rules, take off and the next two laps! By the book that is not the correct procedure! Now we have made that perfect climb and fly two laps up there before we dive. Does that disagree with the rulebook statement of "one full lap of normal normal level flight before the dive??? Also please note that there is no bottom specified in the rulebook for the dive, so it could end anywhere. Also no bottoms specified for the loops or the eights, only the inference of the lap of normal level flight at the start. Thus indirectly implying that six to ten feet should get the better score. If you plan to judge OTS, best you make the flyers aware of how you are going to judge them!
