Beech, Cessna & Piper (models after about 1980) have all recommended full fine for "simulated" OEI operations.
Are there references for that?
(Apparently, the Beech flight manual seems to directly contradict this recommendation and Mix up, Pitch up, Check Power/Power up never takes me THAT long...)
(Remember below about 1800 RPM the CSU is not governing so basically your prop is behaving like a fixed pitch prop and on the B55 it is in course pitch at lower RPMs as well!!! No matter where your propeller control lever is except for the feather detent.)
And slight amendment.....
The governing range covers around 1800 up to max rpm. Correct.
At low rpm, yes it is behaving as a fixed pitch, but because the prop is in a severe underspeed condition, the prop is on the
fine pitch stops trying to increase rpm by reducing the propellor torque (ie. smaller bites of the air).
