Displacement during snap rolls (was Why is it so quiet?)

[Archie Stafford]

What I was trying to say is that there must be a very definitive break in
pitch must be noticeable to guarantee a good score.  Certain judges were
concentrating more on the break than I think they were the entire maneuver.
I understand that the aircraft does not have to have zero lift to stall.
Once again we come back to what is a snap and what is not.  I don’t know
how, but we will always have these discussions as long we have varying
opinions of what is a snap and what is not.  It is one of those maneuvers
that is very commonly scored a 9, 9 ½, and a 0.  The question is now
figuring out which scores are right and which ones are wrong and how to get
rid of the gap between the judges and to help the pilots to know exactly
what everyone is looking for.

Hi Karl,
You already know the answer to that! Rapid application of many "G"s causing
the stall speed to rise.
Of course, first you have to make lift to stall, which meand that you are
starting to leave that perfect vertical line.
 
Happy New Year

All,
 
 
I have a question on the aircraft to be in a "stalled condition during a
snap roll":
How do you get the airplane into a stalled condition on a vertical downline
snap?
