[NSRCA-discussion] Avalanche - Positive or Negative Snap?

[Archie Stafford]

It can be done either way.  Personally I think it presents better by doing
it positive...others disagree, but I think you can maintain the shape of the
loop better with a positive snap.

That's the problem Ken,

"Model pulls or pushes up into a loop, at the top it executes a complete
snap roll, positive or negative, recovers to complete the loop and finishes
in level upright or inverted flight."

That is the total description in the AMA rule book.

Regards,
Michael

I believe the AMA rulebook gives you both for clarity, it you pull into the
loop you need to do a negative snap.  You have to pull in the Advanced
sequence because the plane is entering the maneuver upright.

Of course, I just started to fly Intermediate, so I may be wrong <G>
