What must a pilot obtain before conducting a solo flight?

Before conducting a solo flight, a pilot must obtain a logbook endorsement from a flight instructor. This endorsement is a formal acknowledgment by the instructor that the student has demonstrated the necessary skills and knowledge to fly solo safely. It serves as a way to confirm that the pilot is adequately prepared, understands the aircraft's operations, and is familiar with the specific procedures of the airport where they will be flying.

The endorsement typically includes details such as the date of the solo flight, the instructor's signature, and the specific aircraft the pilot is authorized to fly alone. This requirement is a critical part of training, ensuring that student pilots meet the safety standards established by aviation regulatory bodies before taking to the skies on their own.
