Pilots and ground crew inspect the aircraft for any signs of damage, verify fuel levels, and confirm that safety equipment is onboard. Additionally, pre-flight checks include reviewing the flight plan and weather conditions. This process helps identify any potential issues that could affect the flight. By completing these checks, the crew ensures a safe and efficient journey for passengers and crew members alike.
