Final Answer:
A simple and effective way to control runaway props when preparing to fly is to use a propeller lock or restraining device specifically designed for securing aircraft propellers in place.
Step-by-step explanation:
Controlling runaway props, which refer to unanticipated or accidental activation of an aircraft's propeller, is a critical safety measure during pre-flight checks. Using a propeller lock or restraining device is a reliable method to prevent propeller movement. These locks, often designed with durable materials like steel or aluminum, securely hold the propeller in position, preventing unintended rotation and ensuring the safety of individuals in the vicinity during aircraft preparation.
The propeller lock or restraining device typically functions by physically securing the propeller blades in place, either by using clamps, pins, or other mechanisms that immobilize the propeller. This precautionary measure is especially vital when performing maintenance, refueling, or conducting pre-flight inspections, as it minimizes the risk of accidental propeller rotation, which could lead to injuries or damage. Pilots and ground crew frequently utilize these devices to ensure the propeller remains stationary until it is intended to start, reducing the potential for accidents and enhancing overall safety protocols during aircraft preparation. Employing such propeller locks or restraining devices is a standard safety practice in aviation, emphasizing the importance of precautionary measures in preventing accidental propeller activation
