Which of the following is a common type of aircraft inspection?

A pre-flight inspection is essential in the context of aircraft operations, as it ensures that the aircraft is safe and ready for flight. This type of inspection involves a thorough check of the aircraft's systems, structural integrity, and equipment. It typically includes examining the control surfaces, fuel levels, engines, and other critical components to verify that everything operates correctly.

Conducting this inspection helps identify any potential issues that could pose risks during flight, allowing for timely repairs or adjustments before takeoff. This proactive approach not only enhances flight safety but also supports regulatory compliance and the maintenance schedule.

Ground maintenance, weather assessments, and cockpit checks are important tasks associated with aircraft operation and safety, but they serve different purposes or focus on different stages of the aircraft's operation. Ground maintenance pertains to regular maintenance and repairs performed when the aircraft is not flying, weather assessments are crucial for flight safety but do not involve direct aircraft inspection before flight, and cockpit checks are specific to the condition and operation of cockpit instruments and systems but do not encompass a comprehensive overview of the entire aircraft.
