Which preflight item is used to test aircraft performance before flight?

• A. Performance Check
• B. Airport Facility Directory
• C. Weather
• D. Notices to Airman

Answer: (A)

A preflight performance check is used to verify that the aircraft will perform as published before flight. It involves comparing the actual performance data (such as takeoff distance, climb rate, and landing performance) under the current weight, altitude, temperature, and configuration to the numbers in the flight manual or POH. This ensures the airplane can safely meet required performance for takeoff and climb, and that planned operations are feasible.

The other items serve planning or safety information rather than testing the aircraft’s performance: the Airport Facility Directory provides airport specifics, Weather gives current conditions for planning, and Notices to Airman alert you to hazards or changes. They don’t measure or confirm how the aircraft will perform.
