Snaps

[Del Rykert]

Would be directly in relation to wing loading if the airfoils are practically similar. The higher the load the less the AOA to get wing to stall. Judges can't determine what the wing load is but they can look for the empenage to rotate in cone fashion behind the CG after the wing has stalled. I have scored zeroes when in chair for what I perceived were not stalled maneuvers. This is to some top dogs and used to be hard to do but I have found if I keep my standards high and consistent it became easier with time when manning the chair. Contest flights only last 8 to 10 minutes. Manning the chair can last 4 hours at NATS. For me judging is always harder task.

  I agree with you. That's why I think a video will help all of us to understand the discussed issues better. I hope that there will be more than one video clip.
  The main thing I would like to here comments about is the amount of attitude change needed during the snap. Obviously the airplane must be stalled but no one is flying with AOA sensor on board so the pilot and the judges have to estimate the stall visually. I am interested to see what they expect and how they estimate it.

    Good idea Mike but I have found video can sometimes be misleading as different aircraft present so differently in some ways regarding the snap. This thread has helped show just how challenging it is to judge and fly correctly.

      Hi all,
      Very interesting discussion on a very important issue. As Earl mentioned sometimes a good snap is misjudged because we are used to see the bad one. I think so too. Most of the judges expect too much attitude change and score zero for snaps with small attitude change because they consider it as an axial roll.
      Maybe someone could post a short video that demonstrate how a real 1 1/2 snap should look like.
