In reasonable wind conditions, some pilots can earn a 10 with excellent pilot technique.<br>With increasing wind, it gets increasingly difficult to generate sufficient correction to avoid drift to earn a 10. With even more wind, maybe it gets impossible to generate enough correction to earn a 10.<br><br>I guess that is what we are trying to "fix" with descriptions that "allow for drift near the stall".<br>While I appreciate the attempt to do that, I fear the narrative descriptions we may write will be, subject to inconsistent interpretation and application, and result in less consistent judging of stall turns.<br><br>I'd prefer the descriptions be left as is, and accept that at some amount of wind, a 10 may not be possible.<br><br>Ron Lockhart<br><br>----- Original Message -----<br>From: "Ed Alt" <ed_alt@hotmail.com><br>To: "General pattern discussion" <nsrca-discussion@lists.nsrca.org><br>Sent: Sunday, October 11, 2009 8:53:21 AM (GMT-0500) Auto-Detected<br>Subject: Re: [NSRCA-discussion] Proposed rule change<br><br>

<div><font face="Arial" size="2">I guess I'm getting on a roll this morning. First,
I wish we would stop calling it a stall turn, because the wing never, ever
stalls during the execution of what is actually a hammerhead turn, but I'll let
that go for now.</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">I prefer to go with a description that accounts for
the need to perform wind correction of the line to the maximum extent that is
permitted by the conditions being encountered. I don't think it's
particularly hard to determine this either. If the model has a strong enough,
direct cross wind, there is certainly a point at which no technique is going to
prevent drifting with the wind, and you could objectively determine this if a
continuous correction into the wind to an angle as extreme as 90 degrees will
not offset wind drift. However, there is a considerable amount of
correction that can be applied with the application of some power and
continuously increasing the yaw angle, right up to the point of pivoting
over. I would argue that the criteria should eliminate any mention of
performing exactly a 180 degree attitude pivot, but should instead focus on a
sharp pivot around the CG, such that the path up and down the line do not
diverge by more than X (1/2 a wingspan or whatever). Same goes for
correction in the pitch attitude. A "stall turn" that is properly wind
corrected in both axis is a beautiful thing to observe. No where near easy
to do, and isn't that what this is supposed to be all about, i.e. rewarding the
piloting skill that clearly demonstrates the best depiction of maneuver geometry
under all conditions?</font></div>

and parallel to the flight line.<span style="">
</span>On entry vertical lines must be wind corrected to establish a vertical
track.<span style=""> </span>The wind corrected
attitude of the model must not be changed as the stall is approached and any
wind drift is not cause for downgrade unless the model drifts out of the
maneuvering area.</span></u></p>

<p class="MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;">Here’s
the logic behind the change:</span></p>
<p class="MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;"> </span></p>
<p class="MsoNormal"><u><span style="font-size: 10pt;">Once a crosswind becomes
stronger than the speed of the model the model can no longer maintain a
vertical track even if turned 90 degrees into that wind.<span style=""> </span>Stall turns flown as described in the
changes always score better with the majority of judges.<span style=""> </span>This change brings the stall turn in
line with the spin in allowing some wind drift of the model as it slows and
provides a much more consistent judging standard.</span></u><span style="color: rgb(31, 73, 125); font-size: 11pt;"></span></p>
