If that’s the case then a tight entry radius was done and a large loop at the top was done, then where would the center be for judging purposes? If done correctly, yes, I do agree that the center of the maneuver should be reasonably close to the top of the loop. One shouldn’t look at this maneuver for a center that will be consistent for each pilot. The center will be different – it is the mid-point between the start and end.<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">In the example below – the horizontal lines are identical in length but with a small (tight) entry radius and a large loop – where is the center?

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<o:p></o:p></p><div><p class="MsoNormal">On 4/8/2014 3:22 PM, Derek Koopowitz wrote:<o:p></o:p></p></div><blockquote style="margin-top:5.0pt;margin-bottom:5.0pt"><div><p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Anthony,</span><o:p></o:p></p><p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"> </span><o:p></o:p></p><p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">This shouldn’t be confusing at all… the center of the maneuver is the middle point between the start and end of the maneuver.
