Prop Pitch question...

Top Speed is at maximum rpm and maximum boost, just look at historic performance tests, for top speed they always were at maximum rpm and maximum boost. Why would they do this when there was more speed at lower rpm

CEM is so messed up in this game, I mean, he never really had it modeled.

I believe you got things mixed up a bit. Manual pitch control and constant speed propellers are the same thing. When you set a RPM with your prop lever you are doing two things, changing the angle of the blade AND setting a particular RPM. Neither change with power (manifold pressure) inputs.

If you're confused in game about how to use these things, its understandable since it isn't modeled correctly. Each aircraft has a chart in the pilot operating handbook that shows manifold pressure and prop settings for different phases of flight ie; takeoff, climb, cruise climb, cruise, decent, approach and landing. For full power and speed its always full MP and full Prop. Again, this game doesn't model it correctly and the little tricks learned to do different things in here (concerning CEM) would not work in a real plane, it would destroy the engine.

I fly aircraft with constant speed propellers daily for work, turbines included. My boss would kill me if I pulled my pp back to 50% (as it is in game) and had full power. lol

Here's an example that explains a bit of what you shouldn't do, generally. It puts it into words better than I can.

"For any given RPM, there is a
manifold pressure that should not be exceeded. Manifold
pressure is excessive for a given RPM when the cylinder
design pressure is exceeded, placing undue stress on them.
If repeated or extended, the stress would weaken the
cylinder components and eventually cause engine failure."

Read the Q & A there. It should help explain things a bit. The short answer to someone about pulling your PP back for more speed isn't correct. Again, before you even begin to pull your prop back you have to pull your throttle back or you will damage your engine, just not in game because it isn't modeled.

One last thing, that info is for real world aircraft/flying. In game you can do whatever and have different results, none of which are correct in the real world.
