<DIV><FONT face=Arial size=2>Solutions are hard to come by. I attended
the Kansas contest this year and they have a unique situation where they can
run the two flight lines almost perpendicular to each other. The pilot
stations are about 50 yards apart, but we pit between them and it isn't bad at
all. I expected the interferance factor to be negligible, but that
wasn't the case. The two flight planes were not independent. They
Kindof made a "tee", but the overlap was only a little bit. Anyway, two
planes in the same corners of the box traveling at right angles to each other
felt a lot more dangerous than planes that fly in
formation. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I think its like traveling down the highway with
traffic changing lanes but everyone is going the same way, vs being alone on
the highway but having a cross road where people occasionally drive straight
across your path without stopping. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>After this experience I began to think that the
next best solution is to keep the 2 lines parallel, but put one pilot station
10 yards behind the other (but use the same runway). This offsets the
150m plane so the better the pilot the less the danger.</FONT></DIV>

<DIV><FONT face=Arial size=2>Years ago the list had a discussion on these
percentages (check the archives), then I had two mid-airs in the span of
four contests. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'd say in the 4 1/2 years I've been going to
contests about 50% of the contests have had mid-airs, sometimes multiple
mid-airs. Sometimes both planes lost, sometimes planes were saved. To me
that's a huge percentage. When I leave a contest with no
crashed/mid-aired planes these days I feel we were very
lucky. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Still, if you asked me would I rather risk a
mid-air or fly only three flights I'd go with the mid-air risk to get in the
six flights. After all, we're here to fly, not for static
displays.</FONT></DIV>

<DIV>yes, the risk seems high, but I have been attending contests since
1984, about 4 to 5 a year, and I can remember just 5 or 6 midairs,
and 2 of them were at the Nats. For several years our club had so many
entrys that we ran THREE flight lines, and never had a mid-air. Yes, it is
terrible to lose one of our treasures, but I don't think too many of us
would be happy making our weekend committment and getting to fly just 2 or
3 rounds. That would sure deter me from traveling more than an hour or
two. In reality, I think we have a greater risk of loss just by sheer
number of flights we put on in flying practice. It might be interesting to
see just what the odds are! How many contests are held each year? How many
rounds each contest? How many mid-airs during the course of a
season?</DIV>
<DIV>Then compare that to the average number of flights we get on each of
our own airframes before it's hidden number comes up!</DIV>
