Dave, presents a good argument to fly FAI vs. AMA...AMA is judge more<br>
harshly.<br>

If you are judging by the rules, your answer must be different for FAI -<br>
<br>
5B.8 WIND CORRECTION<br>
All manoeuvres are required to be wind corrected in such a way that the<br>
shape of the maneouvre as described in Annex 5A. is preserved in the model<br>
aircraft's flight. The exceptions to this grading criterion are in the<br>
stall turns, and spins, where the model is in a stalled condition.<br>
<br>
My opinion is that the AMA book should be updated to be consistent with the<br>
FAI book on this topic, and the FAI book is clearly better suited to the<br>
real world dynamics of stall turns in windy conditions.<br>
<br>
To answer Don's original question -<br>
For AMA, by the book, - the maneuver is downgraded for drift.<br>
For FAI, by the book, - the maneuver is not downgraded for drift.<br>
<br>

I'm not sure where the notion came from that wind drift during a stall turn<br>
is not downgraded. In AMA judging criteria the only maneuver that<br>
specifically mentions that no downgrade is given for wind drift is the spin,<br>
and that is only DURING the stalled portion of the maneuver. In a "stall"<br>
turn there is no true stall of the wing as there is in a spin. If flown with<br>
the proper wind corrections on the up- and down-lines there should be no<br>
noticable deviation in distance. If there is, the maneuver should be<br>
downgraded because the pilot failed to make the proper wind correction. Even<br>
if there was a slight drift during the 180 turn at the apex of the lines,<br>
the pilot should recognize that and incorporate the proper adjustment to the<br>
downline to bring the aircraft back to the original starting distance. To<br>
me, it's no different than turbulence that might cause the aircraft to<br>
temporarily deviate from straight and level flight. Adjustments must be made<br>
to return the airplane to th e original line. I don't feel like pulling up<br>
the FAI rule book, so I just won't go there, but I'm not sure if my answer<br>
would be any different.<br>

A question for the judging experts.<br>
<br>
Figure M, both Masters and FAI- Yes I know the bottom line rule the best<br>
presentation gets the best score, but a technical question.<br>
<br>
Maneuver flow in a crosswind. Plane starts maneuver at 140 meters distance<br>
out. During the first stall turn the plane drifts out (recall this is a<br>
stalled maneuver); second stall turn the plane drifts out again (same). Now<br>
the plane wind corrects in all other aspects of the maneuver but exits<br>
approximately 20 meters further out than the entry and no defects observed,<br>
but exit distance is 160 meters. What is the score given for this maneuver?<br>
<br>
Best Regards,<br>
<br>
Don<br>
