[NSRCA-discussion] Judging Question

[Stuart Chale]

Unfortunately FAI does give those percentages.

1. Geometrical accuracy of the manoeuvre; (weighting approximately 60%).

2. Smoothness and gracefulness of the manoeuvre; (weighting approximately 20%).

3. Positioning of the manoeuvre within the manoeuvring zone; (weighting approximately. 10%).

4. Size of the manoeuvre; (weighting approximately 10%).

5. Proportion of the manoeuvre outside of the manoeuvring zone (in addition to the above)


So to answer your question 20% for smoothness and gracefulness. :)  How do you figure that into your non subjective downgrades and providing a final score for a maneuver ???????

It would be hard to write a more unclear paragraph then 5B.9. It says flight speed. Is that airspeed, ground speed, what? Radii performed very tight or very loose. What exactly does that mean? A loose radius would be less smooth or graceful? Huh? Extremely subjective and not really a good way to judge. And then what percentage of a maneuver score should be Smoothness and Gracefulness? I have always thought accurate Geometry should was the primary importance.

This is from FAI rulebook

5B.9. SMOOTHNESS AND GRACEFULNESS OF THE MANOEUVRE
Concerns the harmonic appearance of an entire manoeuvre; i.e. maintaining a constant flight speed throughout the various manoeuvre components, like in climbing and descending sections contributes significantly to smoothness and gracefulness. Radii performed very tight or very loose, though being of equal size within one manoeuvre may be subject for downgrading Smoothness and Gracefulness.

For AMA is smoothness is not well described.  However, I think the first sentence is equivalent to FAI or try to make it similar:

b. Smoothness and gracefulness
A most general definition would relate to providing a smooth, flowing, polished appearance in flight. A perfect set of consecutive rolls should have a constant roll rate from start to finish. A perfect loop must have a constant radius defining a perfect circle. It cannot be made up of a series of straight flight increments joined with sudden angular jerks. Rotations in the pitch axis of the model should be made evenly, and show a constant radius as the model transitions from line to line. Higher marks should not be awarded for flying tight, high-g corners.

I don't think it is incorrect interpretation of the current rulebook.

Agree with Jerry. No downgrade for difference in aircraft speed. If you have been judging for constant speed that is incorrect.

The only reference to center in the list of downgrades is the point of hesitation. Presentation would be poor if asymmetrical in my opinion, hence I believe it would be a downgrade in addition to the change of roll rate which is a listed downgrade. .

An interesting judging question came up the other day and I would like to get some feedback from the group.



Are rolling maneuvers, like the current Masters 2 slow rolls reversed, an asymmetrical maneuver?  If the maneuver finishes the first roll just before center (as it should) then changes the roll rate causing the line length of the second roll to be different from the first, should this be considered a centering error in additon to the change in roll rate.
