[NSRCA-discussion] Snap entry in FAI

Tue Jun 17 20:19:02 AKDT 2008

Thanks Del. 
We are actually on the same page.  My points were directed more 
generally than towards anyone who is posting to this topic.  I just 
wanted to make it clear that personal preferences are not a judging 
parameter and that exaggerated elements in order to please someone who 
is looking pretty much only for certain elements of a maneuver rather 
than the whole is also wrong.  Also, I read posts where people clearly 
don't understand the difference between aircraft pitch attitude and 
angle of attack.  Two very different things.  I see time and again 
people (yes, me too) get whacked for not showing some silly 40 degree 
nose up attitude in order to "prove" the plane stalled before beginning 
a spin.  A wing of course is flown by angle of attack and a plane can be 
at a high angle of attack yet a "low" nose high attitude to the ground. 
So, a high angle of attack and a true stall can occur at a relatively 
low nose high attitude relative to the ground but how often is it 
downgraded or zeroed because the judge does not know the difference 
between the two?  All of the time. I see and hear it all of the time. 
"He could not have stalled because the nose was not high enough" Wrong, 
wrong, wrong.

This link has some basic info for those who want to read even more:
http://www.aerospaceweb.org/question/aerodynamics/q0165.shtml

I also agree that judging is way better than before in just about every 
respect.  We can always make it better of course and these discussions 
make some mad and some frustrated but enlighten others.  If one does not 
truly understand basic aerodynamics, then they cannot become a good 
judge. The concepts of pitch attitude and angle of attack are key to 
understanding stalls and snaps so they are key things that we all must 
understand.  Understanding the difference makes judging these maneuvers 
so much easier.

AMA vs. FAI I also agree completely about having to change gears when 
judging these classes back to back at a contest.  Even trying to keep 
the rules straight for the 2 types is difficult at best.

I hope as well as others that you can continue participating in pattern 
with us!  We need everyone.
