How does an NDB work?

By sending signals that can be read by GPS devices
Through the use of radar to track aircraft
By broadcasting radio waves that pilots can tune into
Via satellite communication for navigation

The correct answer is: By broadcasting radio waves that pilots can tune into

An NDB, or Non-Directional Beacon, operates by broadcasting radio waves that pilots can receive with their aircraft's radio equipment. This system allows pilots to determine their bearing relative to the beacon. The NDB emits a continuous signal that can be tuned into by the aircraft's Automatic Direction Finder (ADF). The ADF then indicates the direction of the beacon relative to the aircraft, helping pilots with navigation, particularly in poor visibility or when flying in areas without visual references. In the context of aviation navigation, NDBs are critical because they provide a reliable means of maintaining course and assisting in approaches, especially at airports located in challenging terrains or conditions where other navigation aids may be unavailable. The other options suggest methods of navigation that utilize different technologies, such as GPS, radar, or satellite systems, which are distinct from the function and operation of an NDB. Understanding the specific mechanisms of NDBs enhances a pilot's ability to navigate effectively and ensure safe operation in the airspace.
