I use it, generally for cruise. From what I've been told, manual settings were never used on the Hs-129. Activating this gives you access to max power, but if you're not careful, you risk ruining the engine. It's also a lot of workload during hairy ground attack missions.

The current system approximates the real thing which had switches rather than a lever. Just check your manifold pressure and rpms.

I see what you mean with regards to setting manual though - there is no hud text indication. It only tells you when you've switched to auto. However, if you look on the instrument panel, you'll see two red switches: up means manual, down is auto.

But I suppose an option is always possible for those who want it.
