Definition
Flights conducted by a student pilot as the sole occupant of the aircraft, performed under the authorization and endorsement of an authorized flight instructor in accordance with regulatory requirements.
Plain English
Flights where the student flies the aircraft alone, with no instructor or other person on board, after the instructor has signed them off as ready.
Context Anchor
Seen in post-solo training, instructor approvals, student pilot limits, and decisions about what a student may practice alone before longer training flights.
Derivation
From the Italian solo, meaning 'alone,' itself from the Latin solus. In aviation it carries this same straightforward sense: the student is alone in the aircraft.
Why Pilots Care
Solo flights develop confidence and prove readiness; they are required milestones on the path to a private pilot certificate.
Intuition Check
Do not assume “solo flights” means a student can fly alone whenever they want. In this context, solo means flying alone only after instructor approval and only within the allowed limits.
Example Sentence 1
After several hours of pattern work, the instructor stepped out and signed the logbook, clearing the student for the first of several supervised solo flights.
Example Sentence 2
Logging the required solo flights allowed the student to move forward to cross-country training.
