What is the primary function of a chip detector?

• A. To regulate oil pressure
• B. To detect ferrous material in oil
• C. To measure temperature
• D. To indicate fuel levels

Answer: (B)

The primary function of a chip detector is to detect ferrous material in the oil system of an aircraft engine or gearbox. This is crucial for maintaining the integrity and safety of the engine, as the presence of metal chips or particles can indicate wear or damage to engine components. By identifying these contaminants, maintenance crews can address potential issues before they lead to more serious mechanical failures. This proactive monitoring helps ensure the reliability and longevity of the engine and contributes to overall flight safety. In contrast, the other options relate to different systems or measurements that are important for engine operation but are not the specific purpose of a chip detector.
