[NSRCA-discussion] How I became an expert Snap Judge (TIC)

[Woodward, Jim (US SSA)]

Hi Vicente,

I don’t think “speed” should be added in any form to the definition, wether its velocity, or rotational velocity.  There should not be anything in the definition that makes the judge look for a particular piloting technique for execution.  The judge shouldn’t care what technique the pilot used.  The judge should only be concerned about the result.  I like Don’s proposed simplified definition.
Thanks,
Jim W.

Jim,



Shall we add speed change?  I remember seen QQ practicing at the Nats when he had the Brio.  It was clear that the plane speed changed substantially during the snap to a point that almost stop.  It was interesting to see how he was adding power to recover during and after the snap.  The speed reduction has been a common denominator when I see good snaps by other pilots.

Good points (again) Don.  I like your simplified approach to defining the snap roll.  Comparisons to full scale flying have no merit here at all.  Some measure of autorotation is easily discernable by watching the nose and tail.
Thanks,
Jim W.

I think part of our problem is the snap we define is not necessarily the
snap the full scale pilots define.  We need to fly to our definition and
call it what we wish.  Maybe get rid of the snap name!  Judges should score
the maneuver based on the pattern definition and not some definition they
believe is correct.  This applies to all the maneuvers in pattern.  The name
of a maneuver should have no bearing on how it is flown or judged.  A good
example of this is our definition of a snap into a spin.  Maybe it's not a
snap but it is what WE call it and the downgrade based on our definition is
10 points.  Real pilots and IMAC have nothing to do with pattern unless we
want to change our focus.

And if you're doing a stall that slow, even if you do manage
to get a "real" snap out of it, you're going to be downgraded
for having your exit line below the entry line (I surmise).

Departure in all three axes seems right to me: pitch, yaw, roll.

"If it's not a roll and it's not a barrel roll, then it's a snap roll."

I think the NSRCA should commission the fellow with the high-def
cameras to do instruction tapes with real pilots flying maneuvers
that the judging team judges to be "right."  That might help.
