Engine out practice

Interesting point of view. Please explain.

There is a potential conflict of interest in that an engine that lasts a long
time delays a replacement sale. However, other factors come into play, such
as liability, reputation and customer goodwill, and so on, so it's not clear
that a manufacturer wouldn't provide good advice.

Lean of peak. In the face of overwhelming evidence both engine
manufacturers flat out state that LOP is harmful to your engine.
Continental has slightly relented as they publish some LOP settings for
their 550 engines. But try and engage anyone in that company in
meaningful discourse on LOP ops and you get blank stares. They
absolutely refuse. LOP not only saves gas but is tremendously easier on
the engine.

For you aircraft owners who do this regularly, how slowly do you
retard the throttle to prevent shock cooling? (I know -- does shock
cooling really exist? For purposes of this discussion, I'll pretend
that it does.)


I don't believe it exists so I'll go from a low cruise power setting of
say 20-21" and 2300 rpm to throttle fully retarded in 3-5 seconds.




Given that the power reduction must be incredibly gradual, do you feel
that this exercise is realistic?


Doing it your way? No.




There really is no chance to
simulate how you must "suddenly" find best glide speed (after your
engine has presumably just crapped out), since you're gradually
reducing your speed along with your power. Or do you put the plane
into a shallow dive as you reduce power, so as not to lose airspeed?


Your just going to have to be content that you are unwilling to
realisticly practice this. Find yourself a friends private dirt strip
field and start 5-7 miles away at 3000 AGL and land on it without
touching the power after you have gone to idle. Another thing I do all
the time is pull the power to idle on the downwind and land without
touching the power.
