This is where the 120 ft decision height really comes into play. I'm not very good at English, but I think this refers to the stoppage of only one engine, not two. Land below 120 ft, continue the flight above it in one engine mode.

I think this because every helicopter has a height/velocity diagram, on which the areas where a safe landing is not guaranteed are marked. I couldn't find the EC135 anywhere on the internet, maybe because it has two engines. That's why I'm uploading a diagram with a single engine, the EC135 can be almost similar without an engine. This shows the approximate altitude from which you can land safely without an engine starting from a horizontal speed of 0 kt.

Yes, you can try autorotation from 500ft.

You won't succeed landing this thing.

Try to watch some autorotation videos..

You'll get to know how much energy a helicopter will be having even after engines are failed..

Even after trading altitude for speed and while slowing to 0 knots, we should be able to hover (by increasing collective)..

From 500ft is possible to landing from autorotation with the Ec135 in this simulator.

Every helicopter is different. I talked to a friend who flew this helicopter until 2009. They did not practice the autorotation landing, only the single-engine landing. Now they can practice on a simulator. He also said that the Ec135 cannot hover from autorotation, it has to be landed by sliding. Ecureuil, for example, can.
