World Championships 2001 Ireland Ireland with luscious green
forests and meadows, spectacular sea side cliffs was the location for the 2001
F3A Precision Aerobatic World Championships held in southern part of the country
in Mallow just 20 km north of Cork the second largest city with a population for
180,000.
Canada
sent a Team of 3 pilots (from right to left) Dezso Vaghy, from Kingston Ontario,
Michael Siddall from Toronto Ontario, Manager Tony Kreg from Mississauga Ontario
and Chad Northeast from Calgary Alberta.
The venue was a horseracing
track in Mallow 25 Km north of Cork in southern Ireland. The flight lines were
located in the grass center of the race coarse park. Two flight lines provided
the flying area for 103 pilots from 43 countries. Each of the two flight lines
accommodated 52 pilots per day all pilots flew preliminary flights on the first
4 days. After all prelims were completed the field was cut to the top 30 pilots
in the world for the semi finals. Canada was successful in putting 2 of our
pilots Chad Northeast and Michael Siddall into the Semi finishing 30th
and 25 respectively. Team Canada finished 12th
out of 43 Countries in the final team standings determined by results in the
prelims. This was an excellent result and all members must be congratulated on
there performance. The top 10 pilots of
the semi finals moved to the finals to determine the world champion.
They flew 2 known F1 flights and 2 unknown flights. F3A

Team F3A Manager New scoring system for the F3A
World Championships 2001. Scorekeeping is the process of
tabulating the marks awarded by judges so as to provide a final ranking of
competitors. This article deals
with some of the logistics involved in the processing of these judges marks. When a competitor flies a
preliminary round, he does so in front of a panel of five judges. The schedule
to be flown in the preliminary rounds is the "FAI Preliminary Schedule, POl".
This involves flying twenty-three manoeuvres in a 10 minute period.
Every judge in the panel awards a score between 0 and 10, (10 being a
perfect score), for each of these manoeuvres. There is also a noise penalty that
may be applied if a judge deems a model to be too noisy.
Once a completed judges score
sheet has been entered for a pilot a "raw score" is automatically
generated. These too have to be stored, resulting in a further 2200 records
being inserted into the database. The next scorekeeping step in a World
Championship is to determine the thirty pilots who will make it through to the
semi-finals. In order to do this,
the judge’s raw scores are processed according to the "TBL"
mechanism. Without delving too much into the mechanism itself, this process
adjusts each judge’s raw score by "stretching" and
"skewing" the values to eliminate any perceived bias for or against
pilots. In any sport, where a group
of individuals are judging the performance of a competitor they will see
different things. A judge may favour one particular style over another, or may
be more in favour of their countrymen. No matter what tabulation system is used
bias cannot be detected and eliminated 100% of the time.
However, it is claimed that with TBL, bias will be removed 90% of the
time. After this "stretch and
skew" phase has completed, another phase in the TBL process will then
discard any of the transformed judges scores that fall outside some
predetermined range. A pilot’s final score for a round is the average of the
remaining scores. .At Mallow, this will result in
about 5% of judge’s scores being discarded as compared to a discard rate of
40% in previous events. This ensures that more scores will count towards
competitors round scores, which is always welcome. This phase results in the
creation of another 440 records. The winner of each round is awarded 1000
points, with the remaining competitors scores being adjusted accordingly.
The best three of the four rounds count towards the final placing at the
end of the preliminaries. The top thirty pilots will carry
forward, as one round in the semi-finals, their final score in the
preliminaries. Each of the thirty will fly two further rounds of schedule "FAI
Finals Schedule, F01 " in front of a panel of ten judges. This schedule
involves flying 19 manoeuvres, yielding another 12000 records, plus 600 raw
scores and 60 round scores. The TBL process is again applied
to provide a semi-final ranking. The first 10 pilots with the best two rounds
now make it through to the final. Each of these pilots will fly four rounds,
each round judged by all 20 judges. Again, as with the previous rounds, there will be a total of 5480 new records. So, in total, the 2001 World
Championships will involve the processing of about 75000 score records, after
which we will have a new world champion in both the team and individual events.
All this will have to be carried out on at least two different computers to
provide confirmation of the result! Reprinted with permission from
