ahh but it does, because you would be adding a maneuver which would 0 the
next maneuver.

I've often thought the same thing, There's no rule that says it's a down
grade or you can't do it. Even if we construe the 15 meters before and after
a maneuver.

Would that mean that the "dead" zone between the exit line of one maneuver
and the entry line of another, if there is sufficient distance, could be
used to reposition the craft on a new heading. In othere words, turn 90
degrees to the flight path then back 90 degrees as to move out or in if
necessary? From this, one would assume the "dead" zone should not be judged.

<<<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.>>>
I think what's being slightly overlooked is the word "minimum". We used to
be required to call "the box" at the pole, (which is the way it should still
be done, but I can't change that) but some ill informed people had that
requirement altered. Why do you think that the word "minimum" is inserted at
that point in the wording? It's not because that's where the box needs to
be called, ( the box can be called at any point between the pole and the 15
meter point) it's because the entry and exit lines, for every maneuver, are
required to be 15 meters in length. This "minimum' requirement specifies
that this is so, if not by pronouncement then by inference. To me this is
quite clear, however, the thing that we can't substantiate even by inference
is whether or not the exit line from one maneuver can also serve as the
entry line for the upcoming maneuver, eliminating the perception of the need
for 30 meters between maneuvers. I have seen instances where this
requirement created a very real test of the box constraints and would like
to see a resolution of this particular conflict. My feeling is that a
superimposition should be acceptable, but that would have to appear in
writing somewhere.

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?
I'm currently gathering information for the next year's judging materials so
this discussion is great. 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:
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.
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.
and more on lines:
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.
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.
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.
Must there be 30 meters between maneuvers? I disagree with Derek here.
Here are the rules on lines.
"(As the lines into and out of maneuvers are part of the maneuver and are
always judged)."
then later
"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."
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.
This needs to be corrected in the next rule cycle.
Sorry for the rambling,
Don
