NDB stands for?

NDB stands for?

• A. Non Directional Broadcast
• B. Non directional beacon
• C. North Direction Beacon
• D. Neutral Direction Beacon

Answer: (B)

The idea being tested is what NDB stands for and how it works in aviation navigation. An NDB is a radio navigation aid that broadcasts a signal in all directions. An aircraft uses an Automatic Direction Finder (ADF) to sense that signal and display the bearing to the beacon, letting the pilot determine position relative to the beacon or follow procedures like approaches and routes. Because the signal is non-directional, it doesn’t point you along a specific course but provides a reference point. NDBs operate in the low-to-medium frequency range, which allows long-range reception but makes readings more susceptible to interference from weather, thunderstorms, and ground conductivity, so they’re generally less precise than modern systems like VOR. The other phrases don’t reflect standard aviation terminology for this aid. The correct expansion is Non-Directional Beacon.
