If all midair collisions were eliminated...

If all GA midair collisions were eliminated, ~99% of GA aircraft fatalities
would still happen.

From Nall Report analysis of U.S. NTSB records:

Total fixed wing GA fatalities:
2002: 518
2003: 555
2004: 510
2005: 491
2006: 488
Total: 2562

Fatalities due to midair collision:
2002: 5
2003: 7
2004: 6
2005: 5
2006: 4
Total: 27

If all GA midair collisions were eliminated, 27 people would still be alive,
based on your own cited statistics. Is saving lives not a sufficient
justification for eliminating midair collisions? Is there are threshold of
deaths below which efforts to eliminate midair collisions are not justified?
What cost is there in attempting to eliminate midair collisions that offsets
the loss of life that they entail?

Oh man...
Excuse me for biting a troll, guys.

mx?

Exactly HOW do you think you can prevent ANY midair?

The ONLY way I can see is to ground everybody.
That'd work!

Training, standardization, caution, discipline, and other techniques can
greatly reduce the incidence of midair collisions.

Well, if you have been following the other posts in this thread
you'd understand that they already ARE doing just that.

Yes. Who said otherwise?

Not only doing it but have done it down to the point of not only
_diminishing_ returns but almost zero additional benefit.

Where exactly in his post did he suggest we should be satisfied with
low numbers of fatalities due to mid-air collisions?

I find that information extremely interesting and I'm glad he posted
it. Thanks Jim!

I also find this interesting. I wonder if the ratio of 100/1 would be
the same if one only considered glider-involved accidents. My guess
is we have a disproportionate number of mid-airs. Any way to check?

You can do the research...

http://www.ntsb.gov/aviationquery/index.aspx

You can select on Injury Severity and Category (Glider, etc.). Play
with trying "collision" etc. in the event details box (but obviously
you need to check the results/misses).
