What does the term "Flyable discrepancies" refer to?

The term "Flyable discrepancies" specifically refers to issues that do not render an aircraft unfit for flight but could affect its performance or safety in specific circumstances. This concept acknowledges that an aircraft might still be able to operate despite certain problems that have been identified.

For example, while an aircraft may still be cleared for takeoff, minor discrepancies—like small cosmetic issues or some non-critical system malfunctions—can still be documented as flyable discrepancies. This allows maintenance teams to track and address issues that could escalate if left unattended, all while ensuring the aircraft remains operational.

The other choices refer to different contexts: maintenance checks refer to routine assessments to ensure airworthiness, a category of discrepancies implies significant problems that indeed prohibit flight, and performance anomalies are distinct from discrepancies as they often pertain to operational characteristics rather than mechanical issues.
