What does each radial emitted by a VOR represent?

Answer: B — An angle from 0 to 359 degrees

Each radial emitted by a VOR (VHF Omnidirectional Range) represents an angle from 0 to 359 degrees relative to magnetic north. This means that when an aircraft receives a signal from a VOR station, it can determine its position in terms of these radials. The radials are expressed in degrees, allowing pilots to navigate towards or away from the VOR station with precision. For instance, if an aircraft is on the 090-degree radial of a VOR, it is located east of the station, while the 270-degree radial indicates it is to the west. This system allows for standardized navigation, helping pilots to follow specific routes or headings safely and effectively. Understanding the concept of radials is fundamental for navigation using VOR, as it aids in situational awareness and route planning.
