What role does the propeller control play in engine-out handling?

• A. Propeller control influences thrust and drag; correct setting helps maintain required RPM and reduces asymmetric drag, aiding OEI controllability.
• B. Propeller control only affects cabin noise.
• C. Propeller control is irrelevant in engine-out handling.
• D. Propeller control adjusts engine oil temperature.

Answer: (A)

Propeller control on a constant-speed propeller sets blade pitch to hold a chosen engine RPM, which directly shapes both thrust and drag. In engine-out handling, you rely on the remaining engine to produce its intended thrust, so maintaining the correct RPM with the prop lever keeps that thrust stable. At the same time, you typically feather the prop on the failed engine to minimize its drag, which greatly reduces asymmetric drag and helps maintain controllability. So, the propeller control is central to managing thrust from the good engine and reducing drag from the failed one, making OEI flight easier to control. The other options don’t reflect the primary role of prop control, which is about pitch, RPM, thrust, and drag, not cabin noise or oil temperature.
