<DIV dir=ltr align=left><SPAN class=121302721-29122004>"Snap rolls represent one
of the greatest challenges to judge. This is primarily due to two factors: (1)
the "snapping" characteristics of different types of aircraft are unique; and
(2), snap rolls are a high energy maneuver that occur very quickly. Snaps happen
so fast, in fact, that is is virtually impossible for a judge to determine the
exact order in which events occur, especially at the beginning of the snap.
There are no criteria, therefore, for seeing nose and wing movement initiated at
the same time as with the other autorotation family, Spins."</SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=121302721-29122004>The rest of the
paragraphs deal with snaps not autorotating through the complete revolutions and
so forth but there is no criteria whatsoever for line displacement. This would
be impossible to deal with actually since aircraft snap so differently from one
type to another. A top level unlimited airplane like an Edge, Cap, or Sukhoi
displaces very little, but people flying lower classes in Decathlons, Clipped
Wing Cubs and so forth displace a great deal in a snap. There's just no way to
fairly judge with a single standard across all aircraft types.</SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=871441121-29122004>No track downgrade
Dean. Since a snap roll is a yaw induced maneuver (or should be at least)
it's nigh-impossible to actually snap the airplane and not displace the line
a little. Especially when you consider the low weight and inertia of our
airplanes as compared to full scale.</SPAN></DIV>
