What is the purpose of an NDB?

The purpose of a Non-Directional Beacon (NDB) is to assist in navigational guidance. NDBs are radio facilities used to provide aircraft with a continuous signal that helps pilots determine their position and navigate to their destination. These beacons broadcast a radio signal in all directions, allowing pilots equipped with appropriate navigation instruments to determine their bearing relative to the NDB. This capability is crucial for navigation, especially in poor visibility conditions or during nighttime flights.

NDBs are part of the air navigation system and play an important role in providing pilots with reference points along their flight path. This helps them maintain situational awareness and navigate more effectively while flying, especially in areas where visual or GPS navigation might not be adequate.
