[NSRCA-discussion] Wind correction

[Earl Haury]

I'll always score the technically correct higher!! 

As a judge I just am amazed at the folks that will wind correct properly on uplines and simply disregard it on downlines - totally destroying a good score. Unfortunately - some judges still can't get past the ugly, the only sure way around this is to score with some sort of machine. 

It takes a lot of practice to develop a "feel" for the wind so as to recognize just what / how much to compensate. Often the pilot requires several maneuvers to get this feel in a competition flight - the judges instantly see the results. The latter may be why some feel wind corrected maneuvers don't score well - it's easy for the judge to see and hard to fly correctly.

How about some technical discussion of wind correcting - we're drawing maneuvers in a moving medium (air) that affects the trajectory of our machine (airplane). Does speed really help - other than shortening the time exposure? Is slower better - gives more time to correctly apply thrust vector "against" the wind? Uplines take some (x) power in calm, additional power is needed for the wind vector (y), how much y to maintain x in calm? Steve's point - downlines are affected by the same wind as uplines, gravity usually is used for x - won't y thrust (adding power) improve downline attitude in wind? Can power be added for y without helping gravity too much (downline speed)?

  Thanx Ken, but which would you score higher??  I know what we are supposed to do, but that is the jist of my post.

      Hey everyone.  While the season is winding down, Don Ramsey and I had an interesting discussion this past weekend.  Am wondering what the general consensus is.

      First, let me state, judges are human and I understand that.  Also, many judges don't know the exact wording of many rules, I understant that also.

      Soooo

      Will a pilot score higher if they follow the letter of the law and wind correct perfectly, but fly an ugly manuever, or wind correct a little and let the plane look "prettier" in a manuever?????

      Lets use the first maneuver in the Master's sequence after entering the box.  Stall turn 1 1/4 rolls up, 3/4 rolls down exit inverted.  On a strong wind day, not pulling to vertical to maintain the line doesn't look to bad (we expect that) the 1 1/4 rolls in centered, looking good, appropriate rudder is given to maintain a straight vertical line (again expected and usually doesn't require much as we are at full throttle), the stall goes off without a hitch, but do to lack of airspeed we cant the fuse and hold rudder into the wind letting the fuse lean at a 45degree angle to maintain a straight line (this is the part I'm curious about) until the 3/4 roll and using a little down elevator to hold the line after the roll (again expected but not ugly)
      Everything about this manuever is done and doesn't detract from the overall appearance of the manuever except the down line after the stall, which is simply "UGLY"

      Just curious what everyone says.  Again, I know what the rules say, and am not interested in a rule book interpretation, but what do you think about scoring better vs worse???

      Thanx
