  It's getting to be that time of year when many of you are wondering not only
what to do with all that time you'd normally be flying, but also what to do
at those monthly Chapter meetings while the airplanes sit shivering in the

Well, I have an answer for both dilemmas: design Knowns and Unknowns, either
individually or as a Chapter project. Making sequence design a Chapter
project will not only give you an agenda for at least one, if not more,
meetings, it can be very educational for the less experienced judges and
competitors in the chapter. Designing a sequence forces use of the Rule
Book, determining catalogue numbers and K's, learning design strategies,
working with the wind, and a host of other skills.

We are in extreme need of Unknowns for all categories, power and glider.
Without new Unknowns, recycling of the 2001 Unknowns will begin very early
in the 2002 season. The only 2002 rule change affecting Unknowns is changing
the figure limits for both Advanced and Unlimited power Unknowns to between
10 and 14 figures. Some new figures are also included in the Intermediate
and Unlimited "legal list," but using those can wait for the Unknowns you
design after the new Rule Book is published. I'm sure you have plenty of
ideas for sequence designs you can use between now and then.

In March, we must provide the U.S.A. proposals for the Unlimited power,
Unlimited glider, and Advanced Knowns for consideration by CIVA for use in
the 2003 season. Last year, the U.S. only had a glider Unlimited proposal.
As one of the strongest members in CIVA, let's not let our interests go
unheard again by not submitting proposals in all three categories this year.

For the CIVA proposal, both the Advanced and Unlimited power Knowns must be
nine figures in length. Normally, the IAC adopts the chosen CIVA Unlimited
Known (technically called, "Programme Q")  without changes as our own
(that's another reason to have a winning proposal!). The chosen Advanced
Programme Q is also normally adopted by the IAC, either "as is" or with the
addition of two or three figures at the end of the sequence to make it a bit
longer for IAC competition. I would like all proposed IAC Advanced Knowns to
be submitted as 12-figure Knowns with the understanding that the first nine
figures would be used for the CIVA proposal and the last three figures held
in reserve should that sequence be chosen by CIVA and should the Board of
Directors elect to lengthen the CIVA Q program for IAC use.

You may submit either the Unknowns or Knowns to me as Visio files, graphic
files, hand drawn on IAC forms, or sketched onto bar napkins. I don't care.
As long as you provide a sequence design and a list of figures, I'll take
care of creating the actual Forms A/B/C.

In addition to the e-mail address accompanying this message, my fax number
is 801-912-7069. So, light the fire, gather up some paper, a pencil, your Rule
Book and the FAI Catalogue and start designing. Who knows, you may get to
fly your own Unknown or Known next year.

My Best to All,

Brian Howard
Chairman, IAC Rules Committee
