CIAM Plenary Meeting 2006 and F5D Rules
The "CIAM Plenary Meeting" was held on
24.-25. March 2006 in Lausanne, Switzerland. What are
the results? Just before Plenary Meeting there had
been some discussions about F3D rules and safety and
due to this also about F5D. But in the end there was
no decision made about changes in F5D.
So we just had the regular proposals which were published
in the agenda before the meeting.
History of Starting
Procedure
Or how it began
Just before 15th November 2005 (closing date for plenary
proposals) the F5 Subcommittee send an proposal to
CIAM that fixes the item that anybody is allowed to
leave the pylon course during the race. Remember: Until
31.12.2003 we had timing commencing at the drop of
the starter's flag and not at the start/finish line.
5.5.6.5.10.
a) (...) Model aircraft will be flagged
off the starting line at 1 second intervals with
timing commencing at
the drop of the flag for that particular model
aircraft.

F5, 01.01.2003 |
The rules had been modified effective 01.01.2004
with timing commencing when crossing the start/finish
line, which is still effective now.
5.5.6.7
Starting Procedure
a) (...) Model aircraft will be flagged off the
starting line at 1 second intervals with timing
commencing when the
model aircraft crosses the start/finish line. (...)
5.5.6.9 Scoring
(...)
b) The flight of each model aircraft shall be timed
with electronic stopwatch or timing device measuring
to at least 1/10 second by a lap counter/timekeeper. Timing
shall start when the model aircraft crosses the
start/finish line for the first time.

There is no reason any more to start directly
at the start/finish line. It is much better now to start
the model some hundred meters outside the pylon course
to cross the start/finish line at full speed. The helper
returns to the pilot during the race. He must cross
pylon basis #2-#3. This starting procedure
outside the course endangers the helper himself and other
competitors too.
Additional Safety
Paragraph
Effective
01.08.2006:
5.5.6.3 Safety Rules
(...)
b) Pilot and helper have to stay inside of the
pylon course from the first drop of the starter's
flag until the last model of the heat has finished
the race or has left the pylon course flight path.

Notice - F5D Electric Pylon Racing
Unanimously approved
by the Plenary Meeting, effective date 1st August
2006. Additionally the rule change may be applied
as a local rule at any competition until the implementation
date. It was further agreed that a "safety
notice" regarding this rule change would be
placed on the CIAM website home page; that NACs
would be informed by email by the FAI and that
the amended rule would appear in all Championship
Bulletins. The F5 Sub-committee Chairman and the
CIAM Technical Secretary would be responsible for
ensuring that these actions were carried out.

What's up in F3D?
Pilot's Area in F3D
The allowed number of models per heat had now been reduced
to three (3) in F3D in 2007, like in F5D in 2006. But
there will be now one circle having 20m diameter
for all 3 pilots and helpers where they have to stay
during race.
The additional second Sideline Judge (blue)
behind pylon judges #1 shall record turns below the top
of the pylon as infringement and he will judge safe side
infringements too. In F5D there is just one single Sideline
Judge but we will test if he is able to judge turn height
2+3 and overall safe side infringements if he is in the
position of the 2nd sideline judge.
There is several more stuff regarding engine
and model aircraft to be found in the Minutes of Plenary
Meeting 2006. But these items are not to be discussed
here.
Pylon Hits and Safety
The general discussion about pylon racing
safety was initialized by one pylon hit during F3D WC
2005 in France. Analysis
shows that this kind of incident occurs with an order
of magnitude 10E-5 over a period of 10 years. It is clear
up to now that there is just one critical
item: hit of no. 3 pylon because of the
small distance to the safe side. This kind of incident
may be avoided in the future.
This season we will test different ways
of judging the height of pylon 2+3 turns. Turns below
the top of the pylons will be scored as cuts in German
Mastership 2006. In the F5 Subcommittee we will discuss
the results of this test in March 2007. In the meantime
every pilot should fly persistent above the
top of the pylons, otherwise Contest Director shall apply
rule 5.5.6.3.e "Persistent flying below the
top of the pylons may be considered dangerous" if
there is any need for. So far the changes and current
safety items in F5D Pylon.
Fly Low, Go Fast, Turn Left!
