What are the essential steps in a standard preflight planning for a VFR cross-country?

• A. Route choice, weather briefing, fuel calculation, weight and balance, check equipment, and NOTAMs.
• B. Only fuel calculation.
• C. Engine run-up; check instrument accuracy.
• D. Landing distance estimation and taxi plans.

Answer: (C)

Before flight readiness, the most critical actions are to verify the aircraft’s systems and instruments are functioning correctly. Performing an engine run-up and checking instrument accuracy directly confirms that the powerplant operates smoothly and that the flight instruments (such as the attitude indicator, heading indicator, altimeter, and airspeed indicator) are giving reliable readings. If there’s any malfunction, you’ll catch it before takeoff, reducing the risk of an in-flight issue or misreading the aircraft’s state during the cross-country.

The other tasks listed—route choice, weather briefing, fuel calculations, weight and balance, equipment checks, NOTAMs, or planning for landing distances and taxi—are all important parts of overall flight planning and preparation, but they are planning and procedural steps rather than the immediate readiness checks that ensure the aircraft itself is safe to fly.
