Prior to takeoff within the holdover time, the crew must accomplish a __________.

• A. Final checklist review
• B. Post-takeoff inspection
• C. Pre-takeoff check
• D. Wing walkaround

Answer: (C)

In icing situations, holdover time is the window during which the applied deicing/anti-icing fluid remains effective. Within that window, the crew performs a pre-takeoff check to verify that the deicing/anti-icing has been completed properly and that the aircraft is safe to depart. This check ensures there’s no remaining ice or frost on critical surfaces, confirms the holdover time is valid and not expired, and verifies the airplane is configured correctly for takeoff. The goal is to confirm readiness before liftoff while the fluid is still active, rather than waiting until after takeoff or relying on a broader, less specific preflight step.
