[NSRCA-dist8] Red Apple Pattern Contest

[Patrick Harris]

Gentlemen,,

We have a very important judging issue that needs to be addressed. In the
June K Factor proof, the Judging Committee took a reversed stance on how a
few FAI maneuvers are to be judged. I will go over this at Wenatchee for
the folks that don't receive this email. Here is the article:

For this month’s column we have a few important clarifications to
make for certain FAI maneuvers. We learned of these issues from
the F3A Sub-committee chairman at the AOC F3A Competition
in Thailand. We then did some research with our compatriots
in Europe and the rest of the world. We decided it was very
important to align ourselves with the rest of the FAI community
in the world and to get this information out as quickly as possible
so that all of our pilots and judges could digest this before our
Nationals and Team Selection event in July.
First, for the FAI Golf Ball maneuver (P15 and F15) we have stated
that the rolls on the 45° up/down lines must be centered on the
line segments AND centered on the center pole. After carefully
looking at the geometry and drawing a lot of pictures we realize we
were mistaken! The rolls MUST be centered on the line segments
that they are contained in, this might or might not mean that the
rolls will be centered on the center pole. In several “normal” loop
size drawings that we have made, they are not centered on the
center pole, they are offset slightly. Depending on the radius of the
loop segments the rolls can properly occur before, at or after the
intersection of the two line segments. As judges we must simply
verify that the roll element is in the center of the line segment
that contains it. Of course the apex of the ¾ loop segment must
be over the center pole for proper centering of the maneuver.

The second clarification concerns the Double Immelman
maneuver that is in both the P15 and the F15 sequences. Under
AMA rules a Double Immelman maneuver is defined as a square
with half loop segments on each end and that is the way we have
been writing about and recommending judging these maneuvers
in FAI. The FAI maneuver however is defined differently; it has no
express relationship between the horizontal line segments and
the half loop diameter. Thus, this maneuver can be wider than it
is tall or taller than it is wide with no geometry downgrade. Bear
in mind though that other downgrades we have mentioned are
still applicable, rolls must begin immediately after loop segments,
loops must be round with no flat spots, etc…
The third clarification is closely related to the second. This
concerns the center Top Hat maneuver in P15. In AMA rules a
center Top Hat is defined as 3 legs of a square. That is the vertical
legs must be equal to the horizontal leg. Again, the FAI rules do
not state this. Therefore, in FAI, a center Top Hat shall have both
vertical legs the same length but there is no required relationship
to the horizontal leg. I.e. it can be wide and short or tall and skinny
with no geometry downgrade as long as the vertical legs are the
same length.

We hope that this clarifies the proper judging of these maneuvers
for you. Please remember, these clarifications are for FAI only! The
AMA rules require that a center Top Hat be 3 sides of a square
and a Double Immelman be a square with half loop segments on
each end when flown in an AMA pattern class.
Remember; never take your eyes off the plane when judging…
Keep your wings level!

See you guys in a few days.

Pat
