WebJun 5, 1998 · Lean during all ground operations except for engine start. It is particularly importantto lean for taxi and runup. Since EGT is usually off-scale at idle power, the best methodis to lean for peak RPM at idle. Lie #8: It’s bad to cruise at high manifold pressure and low RPM ("oversquare"). The old saw about never allowing MP to exceed RPM/100 ... WebMar 19, 2024 · Horsepower is torque x RPM. Reduce RPM, but maintain same torque (manifold pressure), HP goes down. Reduce torque, maintain RPM, and HP goes down. You'll find say, that 2300 RPM and 25" of MP make the same HP as 23" of MP and 2500 RPM. If it's a direct drive engine, prop RPM and engine RPM are the same.

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. WebThis is accomplished by moving the propeller control to full low RPM/high pitch. We watch the RPM for the corresponding drop, look for the MP rise, and also watch the oil pressure gauge.
