Pre-flight checks are essential procedures conducted before an aircraft takes off. These checks ensure that all systems, instruments, and equipment are functioning correctly. Pilots and ground crew inspect the aircraft's exterior, review safety equipment, and verify fuel levels. This process helps identify any potential issues that could affect the flight. Additionally, pre-flight checks include reviewing the flight plan and weather conditions. Pilots confirm that navigation systems, communication devices, and emergency equipment are operational. By completing these checks, the flight crew ensures a safe and efficient journey for passengers and crew aboard the aircraft.
