MON service volume provides reception within how many nautical miles at 5,000 ft AGL?

• A. 100 NM
• B. 60 NM
• C. 200 NM
• D. 150 NM

Answer: (A)

Service volume is the distance within which a navigation aid provides reliable reception at a given altitude. At 5,000 ft AGL, MON’s signal is usable out to about 100 nautical miles. This range reflects the balance of transmitter power and signal propagation at that altitude, including how line of sight, terrain, and interference affect reception. So 100 NM is the practical reach for MON at that height. Smaller ranges (like 60 NM) would underestimate the coverage at this altitude, while much larger ranges (150–200 NM) would require higher altitude or a more powerful/ differently configured facility.
