<DIV><FONT face=Arial size=2>I have always judged snaps with a simple rule -- if
it is not a barrel role, and if the tail describes a helix or cone, then the
plane must be stalled, and therefore it is a snap. I have never downgraded
because the plane is set up with a lot of aileron, so long as the tail wags, and
so long as the nose and tail describe opposing helixes. I don't see
any reference to how fast or slow the plane rolls with regard to
downgrades. To me, a pilot is free (and smart) to set up their plane such
that it loses as little heading as possible in a snap. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Am I completely mistaken on this? A
barrel roll is easy to detect. An axial roll is easy to detect. If
it is not a barrel roll, and not an axial roll, then it must be a valid snap,
even if it is subtle and the plane is not buried deeply in a snap. At
least that is my current understanding.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'll admit that I don't really understand the
degree at which the plane must "break" in the direction of
snap. Who came up with that idea? What really does that mean, and
how do you measure it? "the nose of the fuselage should show a definite
break in the direction of the snap". Ok, what is definite? At what
point exactly must the aircraft become stalled? It takes time for the
control surfaces to deflect. It does not happen instantaneously.

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I think the maneuver is over described and over
analyzed. Its a "rapid autorotation in the pitch, yaw, and roll axes of
flight in a stalled wing attitude." That should be good enough to judge
it. If not, maybe use my definition of judging it. </FONT><FONT
face=Arial size=2>Until I know what a "definite break" is, that's what I am
going to do.</FONT></DIV>
