With reference to the ELT comments, most helicopters I have flown offshore have:-
1. A Ducane underwater sonic locator, so that the helicopter can be found underwater and the 'bodies' removed.
2. A floating type ELT in the cabin to be thrown out if or when the helicopter is floating.
3. An ELT in each life raft.
4. An ELT in each crews life jacket.
Those that have done a HUET course or have had some training should know that you must only activate one ELT to prevent confused signals.
Never having had the "pleasure" of flying any Robinson type, has anyone worked out the AUW with all that fuel on board????
