What day of what contest was this? What was the issue with going
around class C? How was it impossible to continue the course,
impossible to go around class C, but easy to go over? I'm not being
hostile, I'd just like to go look at the task and results. Stated in
the abstract it all seems so unlikely, so it would be good to know the
practical circumstance.

This was the first day of the Southwest Soaring Championships flown
from Tucson Soaring Club. *The CD set a long and challenging task that
proved too long, mostly because of a late start. *Only one contestant
completed the task, three landed out and the rest (including me)
abandoned.


We routinely fly over Tucson Class C as it's often the quickest and
safest way home from tiger country.

I'm still trying to get a sense of whether "this was a real problem"
or whether this is some hypothetical question.


The SSA contest report says this was an area task from El Tiro to
Amado, southwest of Tucson, with a 25 mile circle around Amado. The
direct courseline to Amado doesn't intersect the Tucson class C,
though it does come close; the Tucson class C is east of courseline.
Looking at the chart, I would have flown the line of high ground even
further west of courseline, ending up at Keystone peak or thereabouts.
My options would have been the line of airports, Ruby Star, Flying
Diamond, Ryan, Taylor, all again a bit west of courseline and heading
right back to El Tiro and the second turnpoint. I just don't see how
anyone could have gotten stuck behind the Tucson class C. And it looks
like the CD did *a good job of setting a course that really didn't
cause a problem.


So, tell the story. Where were you guys that you really felt this was
the only safe option? How did you get there? Or is this all
hypothetical?


There is a lot of complaining around here about rules being too
complicated. Carving out an exception for class C overflights in
abandoned tasks is certainly going to be complicated. So it matters
whether this is a real problem, or just the beginning of winter what-
ifs.

John,

I think you've mistaken the Southwest Soaring Championships (a non-
sanctioned local contest) with the Region 9 that was also held at El
Tiro. The task in question was:

* ID * Name * * * * * * * * Distance (Miles) * Radius
* *106 * 106 Waterman * * * * * 0.00 * * * * * * *5.0
* * 62 * 062 MtWshngt * * * * *77.13
* * 12 * 012 Benson * * * * * 126.93
* * 13 * 013 Biospher * * * * 176.85
* * *1 * 001 EL TIRO * * * * *209.27 * * * * * * *1.0

I have a few recollections of making long final glides to El Tiro from
the east. Given the distances involved a long, flat glide would
occasionally get you close to the top of the Class C and in that
instance going around could run you out of glide distance.
Disclaimer: My recollection is decades old and based on the old ARSA
configuration at Tucson IIRC.

Well, if it's non-sanctioned, go ahead and make your own rules, or
exceptions!
