Final answer:
A VOR DME is used in aviation for navigation purposes, providing both direction and distance information to aircraft.
Step-by-step explanation:
A VOR DME is a combined radio navigation station that consists of a VHF omnidirectional range (VOR) and distance measuring equipment (DME). The VOR provides pilots with the direction or bearing to and from the station, while the DME measures the distance between the aircraft and the station. This combined system is commonly used in aviation for navigation and instrument approaches.
For example, let's say an aircraft wants to fly to a specific airport. It can tune into the VOR DME station for that airport, and the VOR will provide the aircraft with the correct radial or bearing to fly towards the airport. The DME will continuously measure the distance between the aircraft and the station, allowing the pilot to track their progress towards the airport.
In summary, a VOR DME is used in aviation for navigation purposes, providing both direction and distance information to aircraft.
