[net.aviation] safety statistics

How safe is flying? I am not a pilot but am considering becoming one
in about a year or so, and am curious about the degree of risk involved.
I obtained the statistic that fatal accidents occur in small a/c at
a rate of about 1 - 5 for every 100,000 hours. To put this in perspective
I have read in a newspaper that the average motorist, in a lifetimes
driving (50,000 hours) runs a 1% chance of being killed. On this basis
flying is considerably safer since the average pilot flies for a shorter
total amount of time. Is this conclusion reasonable? Am I overlooking
anything?

Another thing to keep in mind: most (small) aircraft accidents are the pilot's
fault.  By being careful to avoid the stupid things that kill many pilots
(flying into bad weather, running out of fuel, not paying attention during
landings and takeoffs, flying while drunk or in poor mental shape, etc.)
you can reduce the risk markedly.
Much more than you can do driving a car, where you can only do so much
about avoiding the accidents that are somebody else's fault.

By your own figures the car fatal rate is 1% of 50,000
& hence 2% in 100,000 hours which calculates to .02 in 100,000
which suggests car driving is safer. the fallacy is that car driving averages
over a far larger number of people of reasonable driving skill.
The aircraft figures are for a large number of low experience 
and student pilots. If you follow reasonable precautions
commensurate with your skills & aircraft capability
& you don't get stricken with the 'why bother with the 
weather it looks ok and I have to be there' syndrome;
the accident rate would drop 100 fold from the numbers stated.

But the low experience and student pilots have a *very* good record.
It's almost always the experienced pilot who kills himself and his
family.

Since the FAA is kind enough to send us Arizona airmen regular summaries
of all accidents that occurred in Arizona, I went back through them
and extracted a summary of all the fatal accidents from the start of
'82 through this March.

There were 50 fatal accidents, with a total of 107 people killed.  Of
the 50 accidents, 39 were in high-performance singles, twins, or
experimental aircraft.  Those 39 accidents accounted for 92 of the
deaths.  2 more accidents, and 3 deaths, were in simple single-engine
planes being flown by pilots with commercial ratings.  Only one student
pilot was involved in any of the fatal accidents; interestingly, he was
only slightly injured but his (illegal) passenger was killed.

I've posted the summary in a following message, so that you can see
for yourself what dumb moves people use to kill themselves in my state.
