External load training isn't part of the a twin type rating. Also not on ECD.
There are much TR courses on ECD and nobody have to fly external loads.
Also flight test engineers of the ECD test branch don't taking part on training courses because they are too expensive.
In case of external load operations using this double hook cargo system, it's necessary to have a "hook operator" because the pilot have only a mechanical emergency releasing system on the pitch.
I assume that you was on a flight checking out a problem with this a/c (btw not an ECD ship, it's a helicopter of the bavarian police squadron, one of the first EC 135).
Interesting is to see this a/c is equipped with a double cargo hook. Flying loads attached only on a single hook is only approved on the hook nr.1. But hook number 1 isn't the forward hook... they used the hook nr.2
catched!
