<DIV><FONT size=2>
<DIV><FONT size=2>First, to be clear on the Masters 2/2 Slow Roll
Opposite. Center is defined only after the maneuver ends. Where did it
start, where did it end and only then, was the entire maneuver
centered?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>I'm currently gathering information for
the next year's judging materials so this discussion is great.
</FONT><FONT size=2>Interesting points on entry and exit lines. The
rules are not clear. Consider this, the box entry must be called 15
meters before the first maneuver begins. Each maneuver begins and
ends with a straight line. Here's the quotes from the rules: </FONT></DIV>
<DIV><FONT size=+0><BR><EM><FONT size=2><STRONG>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. Judging will cease at that
point.</STRONG></FONT></EM></FONT></DIV>
<DIV><FONT size=2></FONT><FONT size=2></FONT><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Let's take that a little further. It seems to say,
since a line is part of the first maneuver in a sequence then calling the box
entry should be done 30 meters before maneuvering starts. I don't think
that was the intent of the rule.</FONT><BR><FONT size=2></FONT></DIV>
<DIV><FONT size=2>and more on lines:</FONT></DIV>
<DIV><BR><FONT size=2><EM><STRONG>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.
<BR> All lines within a
maneuver have a beginning and end which define their length. The length of a
line should only be graded when a maneuver contains several lines with a given
relationship, as in a square loop.</STRONG></EM></FONT></DIV>
<DIV><FONT size=+0><FONT size=2><BR></FONT><FONT size=2>I don't think
entry/exit lines have a beginning and end which define their lengths and if
they don't they should not be used for centering
determination. Since the entry and exit lines to a maneuver can and
are often different lengths that would imply those centered maneuvers where
they are different should be downgraded. A good example would be a
turnaround of a half cuban eight, a centered maneuver then a stall turn for
the other turnaround. Should the centered maneuver be downgraded in this
case since the entry and exit lines are of different lengths? Also, the
maneuver descriptions never say, "Model draws a horizontal
line, (remainder of description) ...." The rules never
say the entry and exit lines must be 15 meters only that they must be
there. The implication is, entry/exit lines should not be used in
determining centering.<BR><BR>Must there be 30 meters between maneuvers?
I disagree with Derek here. Here are the rules on lines.
<BR><BR></FONT></FONT><EM><STRONG><FONT size=2>"(As the lines into and out of
maneuvers are part of the maneuver and are always judged)." <BR>
</FONT></STRONG></EM></DIV>
<DIV><FONT size=2>then later</FONT> </DIV><FONT size=2></FONT>
<DIV><BR><STRONG><EM><FONT size=2>"The judge should form an image of the
forthcoming maneuver based on using the straight and level entry identified in
section D, Judging Individual Maneuvers, as a reference. The absence of a
definite entry into a maneuver increases the difficulty of judging its
precision and competitors will recognize this as justification for
downgrading. The straight and level exit from a maneuver is one of the more
valuable portions of a maneuver in evaluating how well the intended course of
the maneuver was followed. Therefore, the absence of a well defined
straight and level exit should also result in downgrading. In all cases,
straight and level flight means flight parallel to the flightline, at a
constant altitude, and with wings
level."<BR> </FONT></EM></STRONG><BR><FONT size=2>Section D does not
include any reference to entry/exit lines. It appears there only need be
a definite or well defined line into and out of maneuvers. That length
is not specified. There is also nothing to preclude the exit line from
one maneuver being the entry line into the next. Again, the maneuver
descriptions do not include the entry/exit lines in their text.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>This needs to be corrected in the next rule
cycle.</FONT></DIV>
