Where is the center on that maneuver? The center is the mid-point between the start and finish of the maneuver (including straight line in and straight line out). There is no definitive middle to these types of maneuvers and so a statement that it is “somewhere in between the 2 ½ rolls” would be accurate as well – it depends on how fast/slow those rolls were done.<u></u><u></u></span></p>

<div><div><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Derek,<br>"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.<br>
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.<br>
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.<br>
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".<br>John<u></u><u></u></p>

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.</span><u></u><u></u></p>
