[NSRCA-discussion] From the Judges Chair

[Atwood, Mark]

I agree with jas. The input radius has to match the top loop radius so it is effectively a center loop maneuver.  The first quarter loop is done down low and the top three-quarter loop is done up high but overall the loop is centered

I don’t think you can leave off the input radius because the input radius size will change where center is located.

I've always enjoyed that pattern had definition (centers, box...) and that's why I don't fly IMAC but once a year if at that.
If the start of the 9 is at the bottom 1/4 loop (minus entry line),
and the end is at the end of the 3/4 loop (minus the exit line),
and the bottom and top radii are equal (as are the entry and exit lines),
wouldn't the center be the start of the bottom loop/middle of roll/top of 3/4 loop/finish of 3/4 loop?

Derek,
"Somewhere in the 3/4 loop portion" is awfully vague and unjudgeable. I could buy anywhere in the 3/4 loop portion but not somewhere.
The center you are describing would appear to be affected somehow by the entry and exit lines of the maneuver as per your description in the March K-Factor. I don't see that. This maneuver(figure 9) could be described as a single loop with a straight vertical line between the first quadrant and the last three quadrants. What rolls occur do not affect that basic shape. That places the center of the maneuver at the initial pullup into a quarter loop just as it would for a simple loop. The apex of the 3/4 loop would also be on the centerline and so would the return to level flight at the exit.
As far as the straight line entry and exit being somehow offset, I don't see that either. The entry line ends at the quarter loop pullup and exit line begins upon completion of the 3/4 loop. Those two points should form a vertical line. I see that as the maneuver centerline as well.
It's certainly true that the aresti shows the wrong center and it is certainly true that the sub-committee chair has the last word but he should be using a better word than "somewhere".

Anthony,

This shouldn’t be confusing at all… the center of the maneuver is the middle point between the start and end of the maneuver.  How much more simple can it get?   The statement that the “middle should be somewhere in the ¾ loop portion” is correct – depending on the size of the ¾ loop which must match the radius of the ¼ loop from horizontal to vertical when the maneuver starts.  That center portion will change for every pilot as each pilot will fly it differently.

Your comment about “many outside the US” isn’t accurate – if they see it differently then they are incorrect.  The clarification I got is straight from the F3 sub-committee chair…

Would love to see a review of maneuver 13 of the Finals sequence. In the March Kfactor the center was described as "should be the middle of the maneuver somewhere in the ¾ loop portion." While the many outside the US see it that the loop is centered and the Aresti in the latest FAI sporting code show the upline being centered.

A bit confusing,

Anthony

Hey guys - we got an excellent suggestion from the group for last month's article so I thought I would ask again! Anyone have a burning maneuver or judging question? Just let me know.

Thanks,
