Floats for EC135
Hi
In summer I plan to fly with EC135 to Norway. Since the trip requires some small sea crossing and there is a lot of Fjords in Norway, my question is about floats. I am pretty sure, that any chopper goes under water like rock, and spinning rotor can kill anyone who tries to escape.
During my type rating, my instructor enjoyed shutting down one engine almost constatnlly, so I know thay EC135 is able to reach shore with OEI under any situation. Do I really need the floats for my trip or not? which other survivable emergencies I can have, where floats can help?
