Which action is performed first when starting a reciprocating engine?

• A. Energize the starter, release after engine start
• B. Mixture control to full rich
• C. Check oil pressure
• D. Apply brakes

Answer: (A)

First energize the starter to crank the engine. The starter provides the initial rotation needed for combustion to begin. Once the engine catches and runs smoothly, release the starter to disengage and protect the starter gear train. Other steps, like setting the mixture or checking oil pressure, come after the engine is turning, and applying brakes is a safety measure but does not start the engine.
