color:#1F497D'>Bill – I can see where the confusion is - as I
perfectly relayed the information as taught in the SE judging seminar and
confirmed in the practical judging practice held on Sundays. The IMAC
judging committee interprets the definition to mean that the attitude
(fuselage) must be in the vertical plane during the rotation. They
further back this up by stating that if the plane were to be in the “wind-corrected”
attitude (not perfectly vertical) during the rotation, that it would be subject
to the 0.5 pt per 5 degree rule. I’ve been in the room 3 times when
Wayne M. has explained this and answered many questions from it.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Lots of discussion took place over this in the judging
seminar. Basically they are teaching that for “yaw” you can
remain wind corrected, but for the pitch axis, you must be in the vertical
plane. Sorry if this seems to contradict the rule, but this is what is
being taught and practiced in the South East. <o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I think it looks funny, and I would prefer for the
interpretation to allow “wind-correction” for any time, but I must
fly what they teach as the scoring criteria SE. On the other hand, I
would love to know if this has changed as well.<o:p></o:p></span></p>

color:#1F497D'>However, this dovetails into the recent IMAC & Pattern
comparison threads. In IMAC, the plane is supposed to be brought into the
“vertical plane” prior to the stall-turn(pivot) taking place.
This is mostly evident if you are flying in a strong headwind where you are
wind correcting the vertical line. Just prior to the stall turn, the
pilot hast to pitch the plane into the vertical plane, then yaw around the
pivot, then return to the wind corrected down line.</span><o:p></o:p></p>

<p class=MsoNormal style='margin-bottom:12.0pt'> Not sure where you got
this about IMAC, but it is incorrect. This may be the cause of your confusion
(from Rule 8.5):<br>
<br>
The wings must remain in the vertical geometric plane throughout the
turnaround, and the aircraft‘s attitude before and after the turnaround
must be absolutely vertical (unless wind correction is required), with no
extraneous tail movement. There must be no rotation around the pitch or roll
axis. If there is movement around any axis other than the yaw axis, often
referred as "torquing" (Fig. 25), there is a deduction of 0.5 points
per 5 degrees of axis.<br>
<br>
At no time in IMAC is the actual attitude of the plane judged, it is ALWAYS the
track of the theoretical center of mass. You are not required to alter the
pitch of the plane at the point if the rotation starts if the pitch attitude in
not vertical due to wind correction.<br>
