[NSRCA-discussion] New FAI Rule Changes

[Vicente Bortone]

Hello all,

I was going to say something similar to Phil and Charlie.  I will add that
even center maneuvers have the same parallax effect that is well described
by Charlie.  Of course it is more pronounced in the turn around maneuvers.
Therefore, I think the #2 rule change is not going to have too much effect
on how we are judging now.  It appears that it is a reaction to the flight
coach (FC) because it is practically impossible for human judges to see
the same level of details that can be viewed using FC.  I believe that FC
can be adjusted to the position that the pilot and judges are in, so it
will still be a very powerful tool that will probably be very useful in the
near future.

Good to hear from all.  I am trying to get ready for this season.  Looking
forward to see all,

Vicente "Vince" Bortone
