<DIV>George,</DIV>
<DIV> </DIV>
<DIV>My suggestion for pilot: Quique. At 2005 Nats he did the best snaps that I ever seen. Of course there are other pilots that could do it but it is just a suggestion.</DIV>

<DIV><FONT face=Arial size=2>I have received several e-mails from some very accomplished pilots who have indicated that they are perplexed regarding the requirements regarding the proper execution of the snap maneuver. Specifically what needs to be shown to the judge in order to score well. Even among the judging community there is a lack of consensus with many misunderstandings of what constitutes a "break" and recognizing the stalled condition and heaven forbid, the auto-rotation.</FONT></DIV>
<DIV><FONT face=Arial size=2>It is apparent that a standard needs to be adopted that will once and for all end the individualized interpretations being submitted from all quarters (mine included).</FONT></DIV>
<DIV><FONT face=Arial size=2>If indeed there is a correct process involved to bring about the proper execution of this maneuver, then it should be possible for the people responsible for handing down the final definitives, to single out the pilot who consistantly performs this maneuver to the precise satisfaction of their judging criteria and have the performance video-taped and made part of the NSRCA web-site and eliminate the confusion.</FONT></DIV>
<DIV><FONT face=Arial size=2>This will enable anyone to visit the web-site, observe the process, and come away with the full knowledge of how to (as Robert Gainey says) score TENS !</FONT></DIV>

<DIV>Kinda like when the judges tell us to slow down, we're flying too fast !</DIV>

This shouldn't be a great surprise to anyone who has thought<BR>>> about the control inputs we prescribe to perform a snap. Elevator i
nput<BR>>> causes the plane to pitch, and pitch causes the plane to displace from<BR>>> its former path, whether the wing is stalled or not. Rudder causes the<BR>>> plane to yaw, but yaw is much less effective at causing the plane to<BR>>> displace from its former path. Rudder during a roll forces the tail and<BR>>> nose to rotate around the flight path. What two things can a judge or<BR>>> pilot look for during a roll to determine if it is a standard roll,<BR>>> barrell roll, or a snap roll? The first is the tail being at an angle<BR>>> that isn't the flight path and then not rotating around the flight<BR>>> path. The second is the CofG staying on a rather straight path.<BR>>><BR>>> A stalled wing (due to elevator application) produces a ton of lift.<BR>>> That lift is going to drastically move the CofG off the previous flight<BR>>> path. This is why I advocate and practice very little elevator<BR>>&g
t; deflection during a snap. Meeting the rules requires strong elevator<BR>>> application to begin the snap, and it also _requires_ releasing most of<BR>>> that elevator during the rotation.<BR>>><BR>>> Of course, this is all just talk and typing. Most important is to<BR>>> ensure your snaps don't tempt judges to whip out the big zero. And that<BR>>> you can hit wings-level every time.
