<font face="Arial">Gray,</font><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> <font face="Arial">Verne</font>

<p><br><font face="sans-serif"><font size=-1>Okay someone please explain
this........</font></font>
<p><font face="sans-serif"><font size=-1>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?</font></font>
<br><font face="sans-serif"><font size=-1>If it is impossible to score
a 10, then maybe the wording needs to change to allow for a heading/line
change.</font></font>

what was taught in the IMAC judging school I attended last year, conducted
by Fred Johnson, who was the chief judge at the TOC and also is an IAC
judge. A properly executed snap will displace the aircraft
from it's original line.</font></font></font>

<br><font face="Times New Roman"><font size=+0>Not sure if this has been
discussed, but Isn't 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></font>

change is a downgrade-1 point per 15 degrees off heading, A barrel roll
is not a snap and earns a 0.</font></font></font>
