<DIV><FONT face=Arial>You have to follow the <U>track</U> of the plane. As the
nose is pitched with elevator, stalling the plane, the application of aileron
and rudder will initiate the rolling part of the maneuver. At that point, the
whole mass is rotating around a point that probably isn't even on the plane but
is on the original track the plane was on when it was started. With proper setup
and execution (requiring lots of practice) it IS possible to have it end up back
on track and heading, but there will be a shift to one side or another. As long
as track and heading are maintained, such as a 45 degree downline, the radius of
a loop, or a simple straight line depending on the maneuver being performed,
there should be no downgrade. The main things to watch for is a defined break in
pitch and the cone-shaped rotation near the tailfeathers. Get all of that and
you've definitely got a snap. After that, it's all track, heading, and
positioning that determines the score. As a judge, it's just about impossible to
see the side to side shift on a maneuver done stage center. I'll bet we'd all be
surprised if we watched it from on end!</FONT></DIV>

<DIV><BR></DIV><BR><FONT face=sans-serif size=2>Okay someone please explain
this........</FONT> <BR><BR><FONT face=sans-serif size=2>A "proper" snap will
change the aircraft's "heading/line". If the aircraft's line is
off 15 degrees it is a 1 point downgrade. These two things do not mesh.
It means there is no such thing as a 10 snap, unless the heading change is
less than 7.5 degrees for a 1/2 point down grade?<BR>If it is impossible to
score a 10, then maybe the wording needs to change to allow for a heading/line
change.<BR><BR><BR>Gray Fowler<BR>Principal Chemical

there a thing with snaps called Displacement, meaning as a break occurs to
initiate the snap, a slight change in aircraft position, will occur. If
this slight change in lateral movement doesn't take place than it can be
argued it wasn't a snap. Some may say heading changed but I'm thinking
that the heading and angle stay the same, just the entire event shifts or
displaces the plane laterally. What say the pilots in the know?? ed </FONT>
