What is one of the first steps before hand-propping an engine?

Before hand-propping an engine, ensuring the cockpit is occupied by a qualified person is paramount for safety. This qualified person is often responsible for checking various systems, including the fuel and electrical systems, and is prepared to react quickly in case the engine starts unexpectedly. They can also communicate with the person propelling the engine, ensuring everyone is aware and coordinated in this potentially hazardous procedure.

The other options, while relevant to operating an aircraft, do not directly address the immediate safety concerns associated with hand-propping. Checking fuel levels ensures the engine can run, raising the propeller may not be advisable unless specific tasks are being performed, and turning on cockpit power might lead to accidental activation of electrical components or systems, which could cause unintended engine start or other hazards. Therefore, having a qualified person in the cockpit is prioritized as a critical safety measure.
