What is crucial when handpropping an airplane engine?

1. Be located in front of the aircraft

2. Have a competent pilot at the controls in the cockpit

3. Ensure all passengers are seated safely

4. Maintain a clear distance from the flight controls

The correct answer is: Have a competent pilot at the controls in the cockpit

When handpropping an airplane engine, it is essential to have a competent pilot at the controls in the cockpit. This is vital because the pilot needs to be prepared to respond quickly in the event of an emergency or if the aircraft starts unexpectedly. A knowledgeable pilot can ensure that the engine starts safely and can control the aircraft effectively if the propeller begins to rotate. Having a competent pilot also means that they understand the specific procedures to follow when performing a hand prop, including the safety protocols for both the person hand propping the engine and anyone in the vicinity. Their training and experience provide assurance that they can handle any situation that may arise, contributing significantly to the overall safety of the operation. While other factors like ensuring passengers are seated or maintaining a clear distance from flight controls may have their significance in general safety protocols, the primary focus should be on having an experienced pilot in charge to manage the engine start process adequately.
