Shy,
My Uncle Sam drew no such distinction between singles and multi's....as i did EOL's in TH-55's, Huey's, and Chinooks. Granted, far fewer in the Chinook as EOL's were not seen to be as likely to be needed.
EOL's in civilian Helicopters are a subject that has many sides to it.
Insurance companies are all about limiting risks to their purse.
CEO's also look to maximizing the "Bottom Line".
That is why we do not do EOL's.
The next best thing is to do power recovery type EOL approaches to landing and hope that we get the Entry done right and control the descent and final stages prior to Touch Down in a proper manner.
If we arrive close to the ground in good shape, with bags of Rotor RPM, a proper pitch attitude and ground speed over a suitable site for landing.....then the odds are we shall survive the landing.
That applies to singles or twins.....and to Simulators as well.
We have to remember Simulators are not the same thing as real aircraft and can only fairly well duplicate the actual aircraft but not perfectly.
Sim's teach procedures and systems not aircraft handling per se.
