What is the correct order of operations for aircraft handling from engine start to taxi?

• A. Start engines, taxi to runway, perform run-up, then complete preflight checks.
• B. Complete preflight checks, start engines, perform run-up, verify flight controls, confirm clearance, then taxi with proper coordination and awareness.
• C. Verify clearance, taxi, start engines, run-up, check flight controls.
• D. Complete preflight checks, taxi, start engines, perform run-up, verify flight controls.

Answer: (B)

The essential idea is to establish readiness and authorization before moving, by following a safe, verifiable sequence that checks the aircraft, confirms power, validates controls, and then proceeds with clearance and movement. Start with complete preflight checks. This step makes sure the aircraft is airworthy, systems are within limits, documents are in order, and the cockpit is prepared for engine operation. It sets the baseline for safe operation. Next, start the engines. With the aircraft verified, bringing power on is the logical next step, not something you do before ensuring all systems and conditions are safe. Then perform the run-up. This verifies engine performance and related systems under controlled conditions, catching any abnormal indications before you apply more complex or riskier actions. After the run-up, verify the flight controls. Ensuring the ailerons, elevator, and rudder respond correctly and without binding confirms you have proper control authority before moving the aircraft. Then confirm clearance. Obtaining and understanding the ATC or supervising authority’s instructions ensures you have authorization to taxi and operate on the movement area. Finally, taxi with proper coordination and awareness. Move with discipline, following clearances, maintaining situational awareness for other aircraft and ground traffic, and using correct taxi procedures. Other sequences skip or reorder these safety checks—for example, starting engines or taxiing before preflight checks, or proceeding without confirmed clearance—creating unnecessary risk.
