Hello to everyone,
I am a quite inexperienced Pilot. I only have about 200 hours at the age of 19. And I just startet my initial training in the SR22, its a great aircraft. After I got all the manuals read, I stumbled again and again over there performance chart. As we all now the SR22 has a combined Prop and power lever. Till a certain point she is increasing the RPM, thereafter holding 2500 RPM and at a specific position (always the same).
When we now look at the Performance Chart, you can see that the manifold Pressure is always the same at full power for different OAT´s. As I understood that actually can’t be possible, because with rising temperatures the density altitude increases. Therefor “less” air is going trough the manifold. So, the pressure (MP) has to be lower. In addition the engine is producing less power in higher altitudes (pressure and density), therefore it’s “pulling” less. I’m very interested in your answer and ideas. And very grateful for any help.
