What does NDB stand for and what does it do?

• A. Non-Directional Beacon; transmits non-directional signals to help pilots home in on the station
• B. Non-Directional Beacon; provides weather data
• C. Network Direction Beacon; provides GPS guidance
• D. National Data Beacon; coordinates traffic

Answer: (A)

NDB stands for Non-Directional Beacon, a radio beacon that radiates a signal equally in all directions. Pilots use an Automatic Direction Finder (ADF) to read the bearing from the airplane to the beacon, which lets you steer toward (or away from) the station and effectively home in on its location. The essence is that the signal itself isn’t directional—the navigation comes from the bearing shown by the ADF, guiding you to the beacon. That’s why the option describing a non-directional signal that helps pilots home in on the station is the best choice. The other ideas—providing weather data, offering GPS guidance, or coordinating traffic—do not describe what an NDB does.
