[NSRCA-discussion] Aresti Figures

Wed Feb 4 02:36:46 AKST 2009

Thanks Troy, especially on the FAI reference. (I completely understand now
why Georgie was told "Aresti takes precedent" as it was in FAI context.I
just wish it stated in the absence of descriptions!)

Another question on FAI scoring.missed point rolls:

If points are not visible or badly-defined during a point roll, or there are
more than the required number of points, the manoeuvre is downgraded using
the 1

point/15 degree rule.

How exactly should this get applied?  Missed point in 2 pt roll: -10, missed
point in 4 pt roll: - 6, missed point in 8 pt roll: -3?

And I'm not quite sure how to apply 1/15 on extra points...

Scott,

Actually if you look at the explanation of Aresti page in your rule
book.look at the figure 9 it's the 3rd one down on the right column. This
has negative then positive elements.

It shows that the 8 sided loop portion should be solid while the entry and
exit lines are dashed.

To define it as it is in the Aresti Catalog a solid line is positive G's
while a broken or dashed line is negative G's. You can be inverted and still
be carrying positive G's.Look at the loop. Or even the outside  loop from
upright entry just above the figure 9. This is how it should be depicted per
the Aresti rules. It's a polygon loop that is positive G from an inverted
entry.

In the 8 sided loop the radii are all positive G's and hence should be
solid. 

We interpret upright vs inverted but this is really not the case. It has to
do with the G load on the airframe and in the case of vertical lines the G
load used in the corner.

It's all kinda subjective a little. After all the 45 degree inverted line
the first leg of the 8 sided is negative G but the corner to get there is
positive.  However on the figure 9 I referenced the radius to get to the
vertical downline is negative G but the downline is drawn as positive G
since the bottom radius to pull out is positive.

Personal preference would probably decide, either one works for the intent.
It's not like you can come from the top down any other way than positive
corners. It's just a  symbol that is short hand for the figure. There is not
a better way to short hand the figures and Aresti is the universal standard.

I think based on my copy of the official Aresti Catalog from 2007 I would
say the polygon loop should be solid line. This is AMA pattern and Aresti
carries zero weight in the judging of the maneuver. In AMA only the worded
descriptor has any judging weight.  

In F3A the Aresti is by definition EQUAL to the word description of the
figure. Especially since the unknown catalog has zero worded descriptors and
all Aresti figures.  Many folks get this confused. Aresti was added to the
AMA rule book in order to eliminate those hard to produce ribbon drawings
and go to a standard that is universally recognized around the world for
aerobatics. It was one or the other for a symbol or a picture. Aresti
symbols have a reason to be there and are graphically easier to reproduce.

That's an eight sided loop

Where ever it is inverted is should be dashed lines. Upright is solid.. 

Doesn't seem right to me.

Is Figure 8 of the 09 Master's schedule drawn correctly?  Entering inverted
from the top, you're pulling pos G's through the maneuver therefore it
should be a solid line.no?
