What allows pilots to navigate directly to or from VOR stations?

The VOR, or VHF Omni-directional Range, is a type of radio navigation system for aircraft that enables pilots to determine their position and stay on course. VOR stations transmit signals in all directions, allowing aircraft equipped with a VOR receiver to determine their direction relative to the station.

When pilots tune their navigation systems to the frequency of a specific VOR station, they can receive these signals and use them to navigate directly to or from that station. By following the radial lines emanating from the VOR, pilots can maintain accurate headings and navigate efficiently in their flight planning. This capability is essential for maintaining situational awareness and ensuring safe flight operations.

The other options provided do not facilitate navigation directly to or from VOR stations. GPS is a different system that uses satellites for positioning, ILS (Instrument Landing System) is primarily used for landing approaches, and ADF (Automatic Direction Finder) relies on radio signals but does not provide the same level of precision or directionality associated with VOR navigation.
