Have you ever flown a piston helicopter? On both the Robinson and the Cabri, there are limits associated with manifold pressure, outside air temperature, time and available throttle.
Yes I have - thank you for asking. It didn’t have a governor either. I also learned to fly in variable pitch propellor FW, that also had MAP limits. But that was in an era where I was taught to set RPM by aural cues (then glance at gauge to confirm) and could set pitch and bank angles by looking out of the window (see other thread about how you don’t do this in an AW139 it seems).
Hey - I have seen the YouTube video explaining how the MLI works, and the cockpit displays look great (no dispute) and will reduce workload, but there is no getting away from the fact that the MAP is the FLI.
