What must be documented before a student pilot can solo?

For a student pilot to be legally permitted to solo, a solo flight endorsement in their logbook is required. This endorsement serves as proof that a certified flight instructor has evaluated the student’s readiness for solo flight and has determined their ability to operate the aircraft safely without direct supervision. The endorsement typically includes the instructor's signature, the date, aircraft make and model, and specific authorization for solo flight.

This process is crucial for ensuring the safety of the student pilot, as it confirms that they have met the necessary training standards and demonstrate adequate knowledge and skills for solo operations. It is a regulatory requirement and part of the overall safety measures in aviation training.
