Hmmmm,............Astounding !!! That same identical pilot informed me of
the same technique. What a small world.

Hi George,
I screw up lots of times. I also appreciate how terribly difficult it is to
write loophole-proof rules.
I have an old Drag Racing acquaintance who worked in Trenton in a
word-smithing team for a legislative caucus.
Even tougher than writing loophole-free laws is lovingly-hand crafting
loopholes!
How do some people sleep ...

If you are looking for examples of vague rules writing, just look at FAI's
judging guide under snap rolls.
In this last revision, someone took the adjective "pitch" out from in front
of the word "break",
probably just to save typing the word yet again.
I actually had one pilot tell me that this wording should allow him to
perform his break entirely in yaw without downgrade.
It fails the horse-sense test: it is a stalled maneuver.

Hey Dean,
I know that this will probably go to your head, but sometimes you are soooo
smart. I have some difficulty understanding the inalbility of individuals
experiencing trouble grasping the obvious and the logical. Often stuff gets
away from me too, so I'm not a stand alone here, but it seems to me that if
you think about the execution of a particular maneuver performed with
unequal line segments, it certainly isn't going to present a pretty or
symmetrical image. It should be pretty simple; IF IT LOOKS BAD, IT IS BAD!
All the rulebook does is to elaborate on this basic concept and no amount of
parsing will alter the end conclusion.
Additionally, I hear guys still asking for clarification regarding roll
direction after the book has been quoted stating that there is no mandate
and  they appear unable to recognize a preference as an individual
presentation bias, NOT A REQUIREMENT. NO guys, you don't have to show the
canopy to the judges on both stalls in the M, but you may be indicating to
casual observers that you have a roll direction that you are less
comfortable with (and no, that's not a reason for a downgrade). Sheeeeesh
!!!!!!!.....................( sorry guys, a little frustration coming out
here. I still love everybody and it's O.K. if you don't love me back).

Sorry Ron, but I disagree with you.
The Figure M must be symmetric. It's that simple.
Even 9 out of 10 non-trained casual observers will eventually, correctly
figure out that both sides should be of equal height.

If the maneuver description is lacking, then we must fix it,
but we must not fall into the trap of carefully parsing imperfectly written
rules
and, producing silly interpretations. This isn't court, and loopholes should
not decide who wins!

I don't agree that the line segments in different parts of a maneuver
necessarily must be the same.  We can use the Stall Turns W/ Half
Rolls to make an altitude adjustment, so the two line would be of
different length and no penalty should be assessed.  The Square Loop
must have line segments of equal length to preserve the geometry of
the loop.
