[NSRCA-discussion] 2007 Masters... clarify on Item20

[Derek Koopowitz]

Fred,

If what you say is the case then every maneuver would be impossible to judge
and that is why we have the the following:

Page 72:

Calling of box entry must be done so there is a minimum of a 15 meter
straight line before the first maneuver. Judging of the maneuver will begin
then. (As the lines into and out of maneuvers are part of the maneuver and
are always judged). Calling of exiting the box must be done after a minimum
of a 15 meter straight line after the maneuver. 

Page 77:

. Lines-All aerobatic maneuvers are started and ended by a horizontal line.
When no line is flown
between two (2) scored maneuvers, the upcoming maneuver should be downgraded
by two (2) points.


The generally accepted length of that line is 15 meters.

So add 15 meters to the beginning of, and end of, each maneuver and you can
figure out the center for those maneuvers that have different rolling
elements such as 2/2 point roll followed by an opposite slow roll.

OK.. then its impossible to downgrade THIS maneuver for centering if the
straight lines are part of it....  Because there is no definite attitude of
the model that can be associated with center, and the line start and end
can't be defined, since there's also straight line exit from the previous
maneuver and entry to the following.

Sorry.

Has to be start of rolling and end of rolling for centering reference and
assumed same length straight at each end. (which can be just one fuselage
length... maybe less since the length is not defined...)

If you don't assume same length straight lines... you can't judge center on
anything.... even a simple loop.

You can purposely shoot for roll rates that center the inverted....  but as
noted... a slow roll probably SHOULD be slower roll rate than the rate for
the 2/2.  which would be likely put put you somewhere in the slow roll
portion at center.
