WebJun 4, 2024 · A variable prop can maintain this optimum AoA at a wide range of speeds, thereby reducing fuel consumption. That's all it does. Fixed wing propellers have a dilemma that at take-off they require maximum thrust, and in high-speed flight the engine will need to be throttled back to prevent overspeeding. WebNov 23, 2024 · In some complex aircraft, the pilot can control the blade angle, and these propellers are called variable pitch or constant speed propellers, while in smaller aircraft, fixed pitch propellers are used. …

WebReducing MP one inch per minute is another good rule of thumb. When flying a fixed-pitch prop, avoid reducing power more than about 400 RPM at a time. Lycoming suggests we maintain at least 15 inches MP during a descent and set the propeller to the lowest cruise RPM position to prevent piston ring flutter.
