When I practiced in my Skylane and also in the club Arrow, I retarded

I have an 0-320, and we probably take 3-5 seconds to smoothly retard the
throttle to idle during simulated engine failure practice. Thinking back
to the *actual* engine failure due to oil loss, the time elapsed between
seeing no oil pressure on the gauge, the initial obvious signs that the
engine was seizing (bucking and shaking), and the time it quit
completely was probably a total of 10 seconds. So comparing the
simulated engine failure to THAT type of actual engine failure, taking 5
seconds to retard the throttle is NOT out of the realm of realism or
accuracy with regard to simulated practice.

To Jay, do you monitor your engine analyzer when you go from cruise
power into the pattern and then pull the throttle back during your
approach? How gradually do you pull power back there, and how do the
temps on the analyzer compare to what you did in the simulated
engine-out practice?
