Hi All,
I'm trying to understand the process for flying with a constant speed prop on a Rotax 912 ULS. There is hardly any information on this in the POH of the aircraft concerned, but I found this in the Rotax operating manual:

From my understanding, I should choose a desired RPM for the fuel burn/speed I want, and set the manifold pressure according to the graph or the table. Am I correct to assume this? Also, I'm aware the MAP will decrease as I gain altitude, but what I am uncertain with is whether I should maintain the MAP shown on the graph (for my required RPM) regardless of my altitude, by advancing the position of the throttle as I gain altitude? I hope this makes sense and any help would be greatly appreciated.
