That would depend on the aircraft.

Airline pilots, for example, can go for their entire careers without
having to deal with an engine failure on an actual flight.
Simulators are invaluable in this case because they allow pilots
to practice engine failures until they become second nature,
without risking an actual aircraft (which would be very dangerous
and expensive).

Wrong again asshole.

I've had catastrophic failures in two nearly new JT8s, shut down three
others, shingled yet another and had to cage two turboprops

What does that mean?

Sorry, tried to get clever. What
does shingled mean?


Sorry. It's slang. The blades on the fans of most fanjets have a set
of shrouds, or snubbers about half span of the fan. They lightly touch
each other, and in fact, when the engines are windmilling in the wind
on the gound, you can hear them clatter against each other. If you
chuck a bird or something in there, you can knock a blade so hard that
it's shroud rises over top of the adjacent shroud and causes a domino
effect throughout the entire fan causing each one to rise up on the
next and twisting the fan blades in their slots. In my indcident, it
happened during the flare when we took a very large bird into the
engine. We knew we'd hit him and had a look at the engine but didn't
immediatly notice any damage. At the same time something didn't look
right and a bit of running back and forth between the two eventualy
revealed the damage. We had to get engineering in form base and they
used the PW approved method of getting them back by prying the first
shingled blade with a lead pipe! I kid thee not. The fan was limited
to 20 hours of operation after that and needed replacing as soon as we
got home.


I've seen a pic or tow of shingling on the net, I think, but most of
the pics I've seen the engines had suffered bad blade damage as well.
It wasn't the case with our incident.
google it though. you will probably find a pic somewhere.
