Question for the Motor Heads

People, you need to go to A2A Simulation and watch the video on props. Find a way to study the CEM on the web...

http://forum.1cpublishing.eu/showthr...560#post280560 top of the page.

The RPM is the engine RPM
The Boost is the manifold pressure (look for it), not the supercharger.
When you use a Constant Speed Propeller, pushing the throttle has the effect of changing the propeller's blade angle to keep the RPM constant, the manifold pressure will show the change as the propeller bites more agressively in the air, and you WILL go faster EVEN if the RPM does not change...This is NOT like a car.

The problem is for people who have never taken a flying course, you cannot guess the CEM...And you generally don't turn with the rudder either as I have seen in many videos. Look up "coordinated turn", the "slip" indicator should stay centered during a turn, you use the rudder to keep the needle straight while you bank the wings with the ailerons and pull on the stick...its quite a trick really to keep the turn level while holding the slip needle centered...Practice makes perfect, but you must to know what to practice.

Again go to A2A Simulation and you will finf the help you need.

PS: I am not affiliated in any way to A2A, its just a great place to learn. Especially look at the two videos on propellers and manifold pressure...study then practice...Otherwise keep away from the CEM.

this easy to understand, but very hard to explain in text :/
