An important one is:
Always instruct your passengers how to release the seat belts, open/close the doors, exit and enter the aircraft.
A heard of an accident few years back where the pax didnt know how to do that and ended drowning inside the aircraft after a ditching, and the same thing can happen if the chopper catches on fire over the land.
Also... when doing an emergency landing on top of trees, go tail rotor first!
