WebJun 5, 2015 · 1. RUNUP. Taking a constant-speed airplane through its pre-takeoff routine is a bit more involved. The propeller control must be pulled back all the way at least once, and more may be required to check manifold pressure, rpm, and oil pressure—all of which will change as the propeller pitch changes. 2. WebMay 12, 2024 · The only regime I can think of, where a Merlin engine (supercharged) would reduce manifold pressure with increased rpm, are extremely low rpm, like idling on the runway. At these rotations, the supercharger is basically too slow to actually work.
