Snap rolls (long)

[Bob Pastorello]

I thought the *whole idea* was to apply "skillful corrections" so that THEY CAN'T be seen....leading to the "if the judge doesn't see it, it can't be scored (up OR down)"

True/False ??

  Try this on Eric,
  The loss of exit heading would a downgrade.
  The fact that the plane is yawed in the snap is not. (its necessary!)
  Either the plane stabilizes instantaneously by iteslf, or the pilot helps it lock back onto the original track, seamlessly.
  OPINION ALERT!
  I think that the skillful correction is not a downgrade. It has to look seamless, though.
  If the snap obviously stops and then (after a discernable pause) a goodly whack of rudder is applied, then that is a downgrade.

     Although it is important to focus on the entry of a snap, a zero is more often earned on the exit of a snap. A single snap is hard to roll out of, but a snap and a half often results in a roll on the last half roll. 

    The snap will often slow down towards the end making the snap look like it is rolling out a little. Try not to misjudge that occurrence. Do look for axially on the last 200 degrees. If it is a roll, give it a goose egg. If you are not sure it is roll then score it..You don't have time to analyze the thing...

    I have shown snap rolls to pilots on my TV and they said, "That was not a snap", and then I ran the same snap in slo-mo, and it was clearly a perfect snap. This thing is hard to judge. A lot goes on in a second or less. Whatever you do, don't blink. I'm serious. You will miss the moment.

    One thing that I am not so sure about is the pilot who can kick in some rudder that straightens the snap out just as it stops. Downgrade or not??

    Eric.
