How are sensor malfunctions normally reported and corrected in the field?

• A. Via fault codes.
• B. Warnings, fault codes, and maintenance requests; immediate actions to maintain safety and mission continuity.
• C. Immediate actions to maintain safety and mission continuity.
• D. By replacing the entire system in the field.

Answer: (B)

In the field, sensor malfunctions are handled with a layered reporting and response approach that keeps safety and mission continuity at the forefront. Warnings alert operators early that something may be off, signaling the need for attention. Fault codes provide specific diagnostic information about the sensor or its subsystem, speeding triage, data logging, and communication with maintenance teams. Maintenance requests turn what’s been detected into actionable work orders, ensuring the issue is tracked, parts are available if needed, and a proper repair plan is followed. Alongside this reporting, immediate actions are taken to maintain safety and keep operations going—such as engaging safe-mode or redundant sensors, isolating the faulty channel, performing quick recalibration or resets if permitted, and adjusting procedures to avoid unsafe operation.

This combination is the best fit because it covers both real-time awareness and a structured path to repair, rather than simply signaling a problem or attempting an ad hoc fix. Relying only on warnings would leave the problem underspecified; focusing solely on immediate actions might maintain safety in the moment but miss a proper fix or documentation. Replacing an entire system in the field is typically unnecessary and impractical for most sensor faults.
