Safety of GA flying

Barney,

Another part of the equation is the reliability of piston engines vs
turbines....


Is it? How many piston accidents are due to engine failure? Is that a
major factor in accidents? In fatal accidents?

In Germany alone at least one each month (often more), according to the
BFU Bulletins.

Accidents? Incidents? Fatal? That's what percentage of all accidents?

I pointed you to the source, now you can do the required research to
answer your question yourself.

Heheh, which means you don't have the facts to back up your claim.

No, which means I'm not going to spend hours to research numbers I'm not
interested in. I know what I've claimed, I'm not interested in exacter
numbers, and certainly not in pecentages. But for those who are, I'll
even post the link with the rough material:

One might also say you posted a meaningless number and I asked you to
put meaning to it. ;-)

One might. On the other hand, one might also say that you asked a
rhetorical question and are not even interested in the answer, otherwise
you would jump on the source and look for the answer yourself.

What I really did was ask Mr. Rubble to explain how much of a "part of
the equation the reliability of piston engines" really is - after he
stated it was.

Yes it is, if you go back to the original question posed by the OP, he was
asking about the root cause of accidents. It is a fact (links at the end)
that Jet/turbine and piston engines have different MTFB's Of course it is
not the only factor in an accident, but engine failure is a fairly serious
matter and not normally something a pilot can do much about (assuming he is
operating the equipment by the book).

To paraphrase the report:-
The in-flight shutdown (IFSD) rate, a measure of reliability, for gas
turbine engines in large commercial aircraft is 0.5 shutdowns for every 105
hours of flight. For single-engine military jet aircraft, the IFSD rate is 2
for every 105 hours. The IFSD rate for light aircraft piston engines is
considerably worse, about 5 to 10 for every 105 hours.

Bye bye
