So, there you are in your nice Medium/Heavy Twin.....La dee F@cking Da...., then Boom!!!! You need to Autorotate NOW!!!!!!!
I have seen so many times in my tenure as a Training Captain, that most 'TWIN' Pilots, have forgoten how to do an auto. This is an alarming fact.
To suggest that emergencies be practiced less often just blows me away!
Just because it hasn't happened to you, doesn't mean it won't tomorrow. Ask someone like Jack Jaworski (S61) or Sylvain Seguin (H500D)
Cheers,
