<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>To add to the common problem…we’re not all flying the same
plane, with the same planform and control deflections, meaning that a valid
snap will look at least slightly different for each person even if performed
with the exact same inputs. <o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Bottom line is that there is a LOT of variance in this maneuver and
what it should look like. Different orientations, wind directions, aircraft,
etc. And while elements are clearly in common, a good snap can still have a
wide variety of “looks”. There is even regional “bias” (sorry, 4 letter
word) based on seeing a lot of the same type of snapping style and getting used
to accepting that as correct, only to go to the nationals and see another
regions version of correct. <o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I have to agree with Ron on the downgrade part. While there is
sooooo much diversity in this maneuver, it seems insane that it’s the only all
or nothing maneuver we have. <o:p></o:p></span></p>

<div>
<p><span style='font-family:"Arial","sans-serif";color:black'>Here is a
description that shows technically correct snap execution, and valid,
consistent judging is possible.<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'> <o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>(Half of the
District One guy need not read this, they have already heard it)

<p><span style='font-family:"Arial","sans-serif";color:black'> <o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>At a small
airport airshow, one of demos was an in-trail formation of four full
scale AT-6 Texans. As each plane got to stage center, it
did a single positive snap roll. Spectators saw four snap rolls in a row, about
5 seconds apart.<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'> <o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>The flight of
four went around, and repeated the maneuver. Some spectators are getting bored
- even a pattern guy could get bored with a string of 8 nearly identical
maneuvers. And then, they did it yet again!!<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'> <o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>What's in this
for us? The snap maneuver by each AT-6 appeared to take a second or
so, from initiation to completion.<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>By the time the
fourth plane did a snap, you could start seeing....<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>- there is
a nose pitch up, <o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>- then a
yaw, <o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>- then
plane rolled in direction of yaw,<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>- plane
returned to straight and level flight.<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'> <o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>By the time the
flight came around for another four snaps, you could see more details….<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>- there is
a nose pitch up, (somewhat sudden, at least sudden for an AT-6)<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>- then a
large amount of yaw, <o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>- then
rapid roll in direction of yaw, (rolling faster than it could with
ailerons) <o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>- plane
returned to fairly close straight and level, nose slightly high.<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'> <o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>By the time the
flight positioned for yet another four snaps, (Yawn, spectators headed for
cotton candy) the four distinct elements of the snap roll maneuver were
easy to see, and there was time to evaluate (judge) each element.<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>1.
there is a nose pitch up, (somewhat sudden, at least sudden for an AT-6,
with little rise in altitude)<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>2.
then large amount of yaw, (the yaw proceeds the upcoming roll)<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>3.
then autorotation at rate faster than it could do an aileron roll)<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>4.
plane returns to level flight track, with nose lowering to level flight
attitude.<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'> <o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>We can all be
expert Snap Roll Judges! Ahhh, at least for AT-6 snaps.<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'> <o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>What I take from
all of this-<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'> <o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>The problem is
not snap descriptions. It’s the application of them; observation,
discrimination and judging of elements in the split second observation time we
have. Is the task beyond reasonable expectations of most of us as a judging
community? I suppose we will continue work started over 10 years ago to
improve in these areas.<o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'> <o:p></o:p></span></p>
<p><span style='font-family:"Arial","sans-serif";color:black'>In the meantime,
shall we reduce the impact of inconsistent judging of snaps by limiting the
downgrade of the snap portion of a maneuver to say….two points2?<o:p></o:p></span></p>
