Possibly to do with needing to keep the casualty at a safe height and give the aircraft a flyaway option - it might just be that even the 145 can't winch at operational weights OEI.

The 145 should be able to operate OEI up to MTOW in that region...

Many operators can hoist/winch to suit using the H145.

Rant or hurt head or not, the operator decided that they would purchase a hoist with the new airframe because all the fittings were there and you can never predict the future. At that time they saw the financial costs associated with hoist training in an environment where there is little call for hoisting [as we know it] were beyond them. They formulated the "retractable long-line" as a business case for adding the kit to the airframe.

It is unlikely they have used it but that was the business case. It is probably easier and cheaper to include than not to on purchase.

In 1980 the Met Police bought a Bell 222 fleet with winches but they took them off as soon as the delivery ceremony was over and never, ever, used them. Ditto the newer EC145s. They have looked at them since .... they do rappelling but no sign of winching yet. Like the 222s [and YAA 145s] they are on the shelf 'just in case'....

I guess its the balance between intensive training [the only sort you should do] and real need. There are enough operators out there that carry a hoist and only switch it on when the operational need presents itself.

But does that include a 2 minute or 30 second OGE OEI hover or a fly away option?

Hi, as long as you operate underneath the Blue line:
Blue line: OEI power limit: Shows the maximum power that will be available at the OEI 30 second limit in case of a sudden engine failure.

But chances are high, if you wonˋt lift off with MTOW at the begining, that you will be able to continue with one engine within the 2 Minute rating which then extends to 2:30 (if 30 sec rating wasnˋt used) or even with some wind wonˋt even need to touch emergency Power at all.

With 700kg Fuel you have an endurance of roughly 3hrs, so itīs quite easy to add some extra reserves not topping up fully!
