In the standard sequence from engine start to taxi, what is the step immediately after engine start?

• A. Perform run-up.
• B. Verify flight controls.
• C. Confirm clearance.
• D. Taxi with proper coordination and awareness.

Answer: (A)

Run-up is done right after engine start to confirm the engine is operating cleanly and within limits before moving the aircraft. By bringing the engine up to a controlled test RPM, you check for smooth idle and stable engine indications (such as oil pressure, temperature, RPM, and magneto performance) and detect any abnormal vibration, roughness, or misfire. Catching these issues at this stage prevents proceeding to taxi or takeoff with a potential engine fault. After a successful run-up, you typically verify the flight controls on the ground (to ensure free movement and no binding) and then obtain clearance before taxi. Taxi with proper coordination and awareness comes later in the sequence, once engine and control checks have been completed and clearance is confirmed.
