[NSRCA-discussion] Judging Question

[Don Ramsey]

I'm surprised no one has mentioned double jeopardy where one error causes
multiple downgrades.  In the case of the rolls, one error, change of roll
rate, causes a centering problem.  Do you downgrade one error twice?

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.
