Which statement best describes the difference between preflight and post-flight inspections?

• A. Preflight assesses readiness for flight; post-flight documents the condition after flight and secures it.
• B. Preflight checks weather; post-flight checks crew rest
• C. Preflight is optional; post-flight is mandatory
• D. Preflight checks only fuel; post-flight checks only landing gear

Answer: (A)

Preflight inspections are about making sure the aircraft is safe and ready to fly. That means checking systems, controls, fuel and fluids, exterior and interior condition, and considering factors like weather and weight and balance to ensure everything is okay before takeoff. Post-flight inspections, by contrast, focus on what happened during the flight and what needs to be done afterward: documenting the aircraft’s condition, noting any anomalies or wear, and securing or parking the aircraft so it’s ready for maintenance or storage. This separation helps catch issues early and ensures a safe handover to the next phase of operation. The other statements don’t fit because weather isn’t the sole purpose of a preflight, preflight isn’t optional in standard operations, and post-flight isn’t limited to just the landing gear—it covers the overall condition and readiness for maintenance.
