[NSRCA-discussion] Where does the maneuver start?

[Derek Koopowitz]

Since the last maneuver is a centered square, the first line of the square is the bottom and thus starts before center. As Anthony mentions all maneuvers start and end with a straight line so one must assume that a straight horizontal line of reasonable length must be visible before that straight line is flown before center.  I would think that the judge would make a determination about the start line once the first vertical portion is started and then they could determine if the straight line in was proportional to the maneuver. 

So, if the first vertical line starts at 50 yards past center then there should have been at least 50+ yards of straight horizontal flight prior to center in order for the maneuver to look like a square and be proportional.

So the beginning would be a straight line of significant length prior to be obviously clear that it is a straight line. If the pilot locks the plane in wings level dead horizontal flight it could be a few seconds or what ever that translates to in distance that could be enough such as after the trombone and before the golf ball in masters.

For the last 2 maneuvers in P one would have to fly a very large half Cuban to encroach on center. This would be a poor presentation if the maneuver are not distinct.
