<DIV dir=ltr align=left><SPAN class=121302721-29122004>The rules for family
9.9 are as follows:</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=121302721-29122004></SPAN> </DIV>
<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>
