In which phase of flight is the takeoff checklist completed?

The takeoff checklist is completed before takeoff, which is a critical part of the pre-flight procedures. This checklist ensures that all necessary systems and equipment are configured properly for a safe departure. It typically includes verifying that the aircraft is ready for flight, checking the status of engines and flaps, and confirming that all crew are prepared for takeoff. This phase is crucial because it helps to mitigate risks by ensuring that the crew has completed all necessary checks before entering the active flight phase.

In the context of aviation safety, emphasizing this procedure demonstrates the importance of thorough preparation and adherence to protocols prior to leaving the ground. Conducting this checklist before takeoff also serves as a final confirmation that all systems are functioning correctly, ensuring a smoother transition into the climb phase of flight.
