discussion</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>Following my mid-air at the N. Dallas contest
this weekend there's been an RCU thread started on the subject. From this
discussion an interesting idea has evolved. For those who would like to read
the thread here's the link: <A
href="http://www.rcuniverse.com/forum/m_6409493/anchors_6413018/mpage_1/key_/anchor/tm.htm#6413018">http://www.rcuniverse.com/forum/m_6409493/anchors_6413018/mpage_1/key_/anchor/tm.htm#6413018</A></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If you'd just like to hear the idea I'll paste
my RCU posting below:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV>
<P class=MsoNormal style="MARGIN: 0in 0in 10pt"><FONT face=Calibri>This is
my third mid-air in four seasons. My first may have been avoided, but the
last two were a complete shock to both me and my caller. In fact, in mid-air
#2 my caller said "you're good" (meaning we were not going to hit). The
other pilot's caller walked up to me and apologized saying that he told the
other pilot that he was in the clear. Therefore, I don't know how effective
a third "spotter" sitting between the lines could be.</FONT></P>
<P class=MsoNormal style="MARGIN: 0in 0in 10pt"><FONT face=Calibri>That
being said, two recent events have given me an idea of how we might be able
to greatly improve this problem. The first light bulb was Vicente's
suggestion of the spotter that warns the pilots. The second event was my
walk out to pick up the fragments of my beloved Brio. As I was walking back
I stood for a bit to observe the planes looking down the flight path. It was
amazing how clearly you can see each plane as it moves in and out from the
flight line. </FONT></P>
<P class=MsoNormal style="MARGIN: 0in 0in 10pt"><FONT face=Calibri>So here's
the idea: What if we sat a spotter at the corner of the box to watch plane
separation in the distance out dimension and then had the other spotter
sitting between the judges (or even back under the cover) watching in the
right to left dimension. These two spotters could use radios with headsets
and continually talk to each other. There are many times that planes appear
to be close to a mid-air from the flight line viewpoint, however, the number
of times that both spotters would be alarmed should be fairly minimal. When
this occurs the spotter could sound an alarm (this deserves discussion as to
the details) and each pilot could peel off of their course. If one pilot
froze the collision may still be avoided by just one pilot taking action.
Sure, this could cause a mid-air, but viewing from two dimensions should
help in alerting only when an impact is probable.</FONT></P>
<P class=MsoNormal style="MARGIN: 0in 0in 10pt"><FONT face=Calibri>Some have
stated that they've seen very few mid-airs, but my experience in D6 and NATS
is that at least 70% (if not more) of the contests I've attended have had
mid-airs. I'm not going to run away crying and quit the hobby due to this
mid-air, but reducing such losses would be a benefit to us all!</FONT></P>
