In the June K Factor proof, the Judging Committee took a reversed stance on how a few FAI maneuvers are to be judged. I will go over this at Wenatchee for the folks that don't receive this email. Here is the article:</div>
<div><br></div><div>For this month’s column we have a few important clarifications to </div><div>make for certain FAI maneuvers. We learned of these issues from </div><div>the F3A Sub-committee chairman at the AOC F3A Competition </div>
<div>in Thailand. We then did some research with our compatriots </div><div>in Europe and the rest of the world. We decided it was very </div><div>important to align ourselves with the rest of the FAI community </div><div>
in the world and to get this information out as quickly as possible </div><div>so that all of our pilots and judges could digest this before our </div><div>Nationals and Team Selection event in July. </div><div>First, for the FAI Golf Ball maneuver (P15 and F15) we have stated </div>
<div>that the rolls on the 45° up/down lines must be centered on the </div><div>line segments AND centered on the center pole. After carefully </div><div>looking at the geometry and drawing a lot of pictures we realize we </div>
<div>were mistaken! The rolls MUST be centered on the line segments </div><div>that they are contained in, this might or might not mean that the </div><div>rolls will be centered on the center pole. In several “normal” loop </div>
<div>size drawings that we have made, they are not centered on the </div><div>center pole, they are offset slightly. Depending on the radius of the </div><div>loop segments the rolls can properly occur before, at or after the </div>
<div>intersection of the two line segments. As judges we must simply </div><div>verify that the roll element is in the center of the line segment </div><div>that contains it. Of course the apex of the ¾ loop segment must </div>
<div>be over the center pole for proper centering of the maneuver.</div><div><br></div><div><div>The second clarification concerns the Double Immelman </div><div>maneuver that is in both the P15 and the F15 sequences. Under </div>
<div>AMA rules a Double Immelman maneuver is defined as a square </div><div>with half loop segments on each end and that is the way we have </div><div>been writing about and recommending judging these maneuvers </div><div>
in FAI. The FAI maneuver however is defined differently; it has no </div><div>express relationship between the horizontal line segments and </div><div>the half loop diameter. Thus, this maneuver can be wider than it </div>
<div>is tall or taller than it is wide with no geometry downgrade. Bear </div><div>in mind though that other downgrades we have mentioned are </div><div>still applicable, rolls must begin immediately after loop segments, </div>
<div>loops must be round with no flat spots, etc…</div><div>The third clarification is closely related to the second. This </div><div>concerns the center Top Hat maneuver in P15. In AMA rules a </div><div>center Top Hat is defined as 3 legs of a square. That is the vertical </div>
<div>legs must be equal to the horizontal leg. Again, the FAI rules do </div><div>not state this. Therefore, in FAI, a center Top Hat shall have both </div><div>vertical legs the same length but there is no required relationship </div>
<div>to the horizontal leg. I.e. it can be wide and short or tall and skinny </div><div>with no geometry downgrade as long as the vertical legs are the </div><div>same length.</div></div><div><br></div><div><div>We hope that this clarifies the proper judging of these maneuvers </div>
<div>for you. Please remember, these clarifications are for FAI only! The </div><div>AMA rules require that a center Top Hat be 3 sides of a square </div><div>and a Double Immelman be a square with half loop segments on </div>
<div>each end when flown in an AMA pattern class.</div><div>Remember; never take your eyes off the plane when judging… </div><div>Keep your wings level!</div></div><div><br></div><div>See you guys in a few days.</div><div>
