Which VOR service volume covers the altitude range of 14500 to 18000'?

The VOR (VHF Omni-Directional Range) service volumes are defined by their operational range and the altitude at which they are effective. For the specific altitude range of 14,500 to 18,000 feet, the VOR's service volume extends out to 100 nautical miles.

This service volume designation is important for ensuring that pilots receive reliable navigation signals at the specified altitudes. The use of a VOR at higher altitudes can assist pilots in maintaining situational awareness and in navigating airways safely, especially when flying at significant distances from the VOR station itself.

Understanding these service volumes is crucial for instrument flight rules (IFR) navigation, as it affects route planning and the choice of navigational aids. The 100 nautical miles service volume is designed to encompass critical airspace used by IFR traffic, allowing effective use of VOR signals for navigation throughout that altitude range.
