What must be ensured before takeoff in regards to the aircraft?

Before takeoff, ensuring the proper configuration of the aircraft is crucial for safe flight operations. Proper configuration involves verifying that all systems and components of the aircraft are set up correctly for flight. This includes checking the flight controls, navigation systems, braking systems, and any necessary equipment that is vital for the aircraft’s operation during takeoff and subsequent flight phases.

This check ensures that the aircraft can respond correctly to pilot commands and perform safely under various conditions. Having the aircraft in the right configuration directly affects its performance, handling, and safety margins, thus making it a priority before departure.

While proper loading of passengers, clear weather conditions, and complete fuel tanks are also important considerations, the immediate priority focuses on ensuring that the aircraft is configured correctly to handle takeoff and flight dynamics effectively.
