What should a CFI verify during a pre-flight inspection?

The primary responsibility of a Certified Flight Instructor (CFI) during a pre-flight inspection is to ensure the aircraft's airworthiness. This involves checking that all components of the aircraft are functioning properly and safely before flight. Key aspects include examining the aircraft's documentation, such as the airworthiness certificate and registration, as well as conducting a thorough inspection of the aircraft's physical condition. This means checking the fuel levels, control surfaces, tires, and overall structure to make sure there are no visible defects or issues that could affect the safety of the flight.

While verifying weather patterns, assessing pilot readiness, and considering passenger comfort are also important aspects of overall flight preparation, these do not directly pertain to the aircraft's functional ability to safely conduct the flight. The focus on airworthiness ensures that the aircraft is mechanically sound and compliant with aviation regulations, which is critical for operational safety. This pre-flight diligence helps in preventing accidents and ensuring a safe flying experience.
