Many moons ago when I flew the AS332L, I had a sim session when the examiner "failed" both engine FCU's and both engines went to 28000rpm (or thereabouts).
We got back onto a runway by bringing one engine FFCL to idle (fast reduction?) and by using the other engine FFCL manual range to control rotor RPM we carried out a single engine profile run-on landing and then shut down both engines immediately after landing as I lowered the collective.
As far as I can remember, it must have involved a total electrical failure as the only engine/rotor indications indications we had was the P2 mini RPM needle and listening to the sound of the rotors which gave a good indication of falling or increasing RPM. We lost all intercom as well obviously.
