What function does a VOR (VHF Omnidirectional Range) serve?

A VOR (VHF Omnidirectional Range) is a key navigation aid used by pilots for determining their position relative to a VOR station. The VOR broadcasts radio signals in all directions, enabling aircraft equipped with VOR receivers to determine their bearing from the station. This information allows pilots to navigate effectively by following specific radial courses to or from the VOR, which is an integral part of IFR (Instrument Flight Rules) navigation.

Using a VOR effectively allows pilots to maintain situational awareness, especially when flying in areas where GPS signals might be weak or unreliable. By interpreting the VOR signals, pilots can chart their course and ensure they are on the correct flight path, making it a vital tool in enroute navigation.

The other options do not accurately reflect the function of a VOR:

• Providing altitude data is not within the scope of VOR; rather, altitude is typically monitored using altimeters.

• Fuel calculation is done based on various flight data but is not a function of the VOR system.

• Measuring airspeed is accomplished by a different instrument called an airspeed indicator and is not related to VOR operations.

Thus, understanding that the VOR provides position information relative to its location clarifies its crucial role
