Which identifier is assigned to many Non-Directional Beacons (NDBs)?

Non-Directional Beacons (NDBs) are typically designated with two-letter identifiers in aviation navigation. These identifiers are straightforward and provide pilots and air traffic control a simple way to recognize specific NDBs. The two-letter designations are standardized and are utilized in air navigation charts and for communication purposes, ensuring clarity and avoiding confusion among numerous beacons.

In aviation, identifiers serve as a means to reference navigational aids efficiently. While other systems such as VORs and waypoints may use different formats for their identifiers (like three-letter codes), NDBs distinctly follow the two-letter system, originating from international standards set by aviation authorities. This standardization allows for consistency in navigation and reporting, which is vital for safety and operational efficiency in the aviation environment.
