What is the purpose of moisture drains in the pitot-static system?

• A. To measure air speed
• B. To remove contaminants and moisture
• C. To enhance ice control
• D. To provide altitude readings

Answer: (B)

The purpose of moisture drains in the pitot-static system is to remove contaminants and moisture. In aviation, the pitot-static system is crucial for measuring airspeed and altitude, as it relies on the accurate sensing of air pressure. Moisture and debris can accumulate in the system, leading to erroneous readings and potentially affecting the aircraft's performance and safety. The moisture drains serve to keep the system clear of water and other contaminants, ensuring that the pressure measurements remain accurate and reliable. This maintenance is essential for the proper functioning of flight instruments, particularly in adverse weather conditions where moisture is more likely to present a problem.
