"Peronal Flying" (from Nall Report)
Hours 47% of light GA
Fatal Accidents 72% of light GA
Fatal Rate: 2.65/100,000hrs.

I was curious how this number matches with driving, and on a per miles
basis. I didn't see any statistics for automobile accidents on the
NTSB website, but I found a website that listed the deaths per
vehicle-km.

Guesstimating that the average GA plane flies 140mph.
Fatal accident rate = 2.65 / 14M miles -or- 1 fatal accident per 5.3M
miles

The webpage above lists 9.4people killed per billion vehicle-kms.
Converting to miles yields: 9.4 per 625M miles -or- 1 per 41M miles.

Since the car statistics are 'people' killed per mile, and not fatal
accident numbers per mile, the car numbers are actually better than 1
fatal accident per 41M miles. Since most vehicles are operated solo,
the factor is probably 2, but is obviously higher than 1.

This seems about right. If it is about 5x on a distance basis it is about
15x on a time basis. The numbers could be off by quite a bit and personal
flying would still be significantly more dangerous than driving and vastly
more dangerous than airline flying.
