Cirrus SR20 and SR22 aircraft feature a simplified combined throttle and propeller control, known as a "power lever," to enhance ease of learning, reduce pilot workload, and protect the engine.
This single lever mechanically links throttle movements to propeller pitch adjustments via a cam and governor, automatically setting appropriate RPMs based on power demand.
While some pilots perceive a lack of direct RPM control, the system effectively manages propeller speed within a narrower range, ensuring it typically stays above 2,500 rpm at high-power settings, similar to a conventional prop control.
There’s something to be said for simplicity when teaching people to fly or merely checking out in a new aircraft. Simplicity was Cirrus’ motivation behind this month’s feature, the combined throttle and propeller control that’s standard on both the Cirrus SR20 and SR22.
