RVDT, the winch can also be used for training, not just for a real emergency.
Only if "CASA" says so as nobody else will.
Most RFM supplements by manufacturers do NOT mention the fact that humans will ever be on the end of the cable.
They avoid the liability and that is up to you to prove along with your NAA and ops manual etc. Terms used are "cargo" or "object".
Pretty much standard in RFM supplements -
The external load equipment certification approval does not constitute operational approval; operational approval for external load operations must be granted by the local aviation authority.
Just so that you are aware that if it does go pear shaped you better have your ducks in a row.
How your NAA substantiates it would be the sticking point. :roll eyes:
There are or used to be quite a few operations with winches in Aus where it is Human External Load and NOT an emergency.
i.e. Part 133 D or equivalent.
RFS and Frogs and Logs comes to mind. Way out on a limb - excuse the pun.
