Which statement describes Conditional maintenance?

• A. Preventative maintenance
• B. Conditional maintenance
• C. Routine calibration
• D. Replacement of all components after each flight

Answer: (B)

Conditional maintenance means doing maintenance only when a specific condition is observed or a fault is detected, rather than doing it on a set schedule. In drone practice, you’d perform repairs, part replacements, or adjustments when the system reports a fault, when telemetry shows abnormal readings, or after an inspection reveals an issue. This approach focuses on addressing actual needs as they arise, keeping equipment safe and available without unnecessary work. Preventative maintenance, by contrast, is scheduled in advance based on time or usage to prevent failures. Routine calibration involves regularly calibrating sensors at fixed intervals regardless of condition. Replacing all components after each flight is not how maintenance is described or practiced, since it would be wasteful and unnecessary.
