Known sequences for 2013 are now posted on the IAC.org Members section.

Click here for a direct link to the 2013 knowns.  Links to the individual sequences are at the bottom of this post.  The Sportsman known is posted below.  No spins or cross-box figures in this years’ sequence; altitude management will be the name of the game when you get to Figure 9.

Curiously, there are no spins in the Intermediate sequence, either.

Proposals are out for 2012 rules changes and known sequences.

There are 4 proposals for the ’12 Sportsman Known sequence, and 5 proposals for the ’12 Intermediate sequence.

Two proposed rule changes that would affect a number of our members:

1. Add 500 ft. to the top of the box for Primary and Sportsman sequences.
2. Require the first figure in the Primary known to be flown into the wind.

There are a couple other rule changes that may pique your interest as well:

1. Specify a methodology for downgrading a change in radius for looping lines.
2. Optionally removes the requirement for a competitor to wear a parachute if flying
   an aircraft with a ballistic recovery system.

The proposed knowns are interesting as well.  For those of you who flew the Sportsman in 2011, you remember there were two figures with 45 deg lines in the same line on the X axis.

This resulted in a number of competitors either taking a break or being penalized for an out on the upwind side of the box.

One of the proposed Sportsman knowns removes this characteristic of the sequence. There may be disadvantages as well.

EAA has a forum set up to officially comment on both the proposed sequences and rule changes.  Take a look at the proposals in the discussion on the Unusual Attitudes forum by clicking on this link:  Proposed Knowns and Rules for 2012

You may read many of the constructive comments on that thread, and provide your feedback in that forum as well.

Note: The Unusual Attitudes Forum will be the ONLY place for members to make official comment on these proposed rules and knowns.

The 2011 Known Sequences have been published, and are available on the IAC.org Members Only section.

It appears as though the Sportsman Proposal “B” won out, however in the published sequence figures 5 (the roll) and 9 (the loop) were swapped.

Unfortunately this change doesn’t alleviate being blown out of the box during figures 6, 7, and 8, but it does give you an opportunity to carry a little extra energy going into the loop.  Additionally, the loop should leave you with a little extra energy going into the Cuban.
