Snap Switch

[Ed Alt]

Sorry, I should have referred to track, not heading.

  Gray:
  Two aircraft flying a straight line in perfect wing abreast formation will be on the same heading, but displaced from each other.  Displacing the model from the line entering the snap can be thought of in exactly the same way.  At the end of the snap roll figure, the model is displaced some distance from it's original line, but should immediately resume a new line on the same heading. Displacement can be in both the horizontal and vertical planes.

    Okay someone please explain this........ 

    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?
    If it is impossible to score a 10, then maybe the wording needs to change to allow for a heading/line  change.

    This is exactly 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.

    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

    Yes, the heading change is a downgrade-1 point per 15 degrees off heading, A barrel roll is not a snap and earns a 0.
