What is the maximum flight time allowed for a student pilot?

The maximum flight time allowed for a student pilot pertains to how long a student may act as pilot-in-command of an aircraft without additional training or review. The correct answer reflects that a student pilot is limited to a maximum flight time of 90 days since the last solo flight or since the last time they have received a flight review from a certified flight instructor. This regulation ensures that student pilots remain proficient and safe, as it encourages them to regularly practice their flying skills and reinforces the importance of consistent training.

The other choices do not apply to the context of student pilot flight time limits under the regulations. For instance, 30 and 60 days lack sufficient time for skill retention and competency development that is necessary for a student pilot's progress. The option of 120 days exceeds the regulatory framework established for student pilots, which emphasizes safety and proficiency within a 90-day period. Adhering to this timeframe helps foster a habit of continuous learning and practice, which is crucial for successful solo flights.
