Which class of NDB service volume has a maximum range of 75 NM?

• A. Compass Locator
• B. Medium High (MH)
• C. High (H)
• D. High High (HH)

Answer: (D)

The class of NDB service volume that has a maximum range of 75 NM is the "Compass Locator." This is a specific type of Non-Directional Beacon (NDB) that is primarily used to provide guidance for approaches, typically associated with precision approaches. The maximum range of 75 nautical miles pertains to its intended application, which facilitates navigation for aircraft at lower altitudes during the approach phase, rather than longer distance navigation. Understanding the different service volumes is essential for pilots, as it affects how and when they can rely on NDBs for navigation. Other classes such as Medium High, High, and High High offer different ranges, with Medium High providing coverage of 150 NM and High categories extending even further, thereby serving different operational needs. The range capabilities and purposes will guide pilots in selecting the appropriate navigation aids for their flight operations.
