[NSRCA-discussion] New FAI Rule Changes

[Mark Atwood]

Hey All,

Attached are the results from the CIAM plenary meeting and vote that took place on April 1st.  These rule changes will go into effect in 2024.  Most of the rules that address F3A are minor and merely clarify clerical issues in the rulebook or help outline procedures.  There are also changes to the wording around telemetry, but again, only for better clarity. But there are TWO notable rule changes.  Neither of which we supported.

1) Increase the weight limit to 5.5Kg TAKE OFF WEIGHT.   This is a straight up increase for electric, and a change to weighing procedure for glow planes to include FULL tank of fuel.   The issues here are obvious and I know we have many on both sides of this discussion, but it’s the new rule in FAI.

2) This one confounds me.   They have changed the judging guidelines, such that they no longer want accurate geometry relative to the aircrafts plane of flight, but instead want geometric accuracy FROM THE JUDGES PERSPECITVE.    In other words, a half loop at the end of the box needs to LOOK round, rather than BE round relative to the plane of flight.   It completely changes our way of flying and makes tools like flight coach useless.  

Personally, I can’t imagine this will last, and more over I can’t imagine this will actually be used.  A few of us (US/ UK / AUS) fought hard against it, but in the end it won out.  They had no explanation as to how cross box maneuvers will accomplish this (such as a rolling circle) but insisted this is what was wanted.  I’m sure there will be much discussion at events prior to this going into effect.

There were also some minor changes for how ties are handled and better language and procedure for handling smaller championship events (<40 pilots). But most of that is benign.
