What is the main purpose of a preflight inspection?

The main purpose of a preflight inspection is to identify any potential issues that could affect safety. This thorough check ensures that the aircraft is in a condition that is safe for flight. During the inspection, pilots and crew examine various systems and components, including the airframe, engines, and crucial safety equipment, to detect potential problems that could jeopardize the safety of the flight. Addressing any discrepancies before taking off is vital for preventing in-flight emergencies.

While preparing passengers for the flight, checking fuel levels, and confirming the flight plan and route are all important aspects of preflight procedures, they do not encompass the primary goal of the preflight inspection itself, which is fundamentally centered on safety assurance.
