I do agree !

Actually the throttle is ALWAYS a power lever, CS or no. What you mean, I
think, is that with CS the tacho is NOT a measure of power.

Don't suggest that to the PFA for g*d's sake !
Actually the Rotax Operating Manual shows that it is not possible to
overload the 912S engine at either 5 minute revs (5800) or max continuous
(5500). It shows manifold pressure values to define the 75%, 65% and 55%
power levels. For the purpose of economy not for the purpose of engine
preservation.
So I am going to argue that the gauge is not needed. I will let you know.
The PFA inspected the Airmaster on a 914 engined Europa. This comes with a
Turbo boost gauge and this is necessary in case the wastegate sticks closed.
The turbo boost gauge obviously acts as a manifold pressure gauge as well !

I am waiting for his return - "Seconds out - ding ding" :-)
