WebDec 28, 2024 · The propeller is mechanically or aerodynamically driven to fine pitch (high RPM) while the governor uses oil pressure to coarsen the pitch (lower the RPM). Upon loss of oil pressure, the propeller will go to the low-pitch (high RPM) stops. Fail to Coarse: This is the default in twin-engine piston aircraft. WebApr 27, 2024 · A traditional fixed-pitch propeller aircraft has a throttle (black knob or lever) and a mixture control (red knob or lever). An airplane with a controllable-pitch propeller, also known as a constant-speed prop, has an additional blue knob or lever that is often placed between the throttle and mixture control levers. george b swift elementary specialty school
