What is the range of a VOR service volume from 45000 to 60000 feet?

• A. 100 nm
• B. 130 nm
• C. 40 nm
• D. 60 nm

Answer: (A)

The range of a VOR service volume for altitudes between 45,000 and 60,000 feet is indeed 100 nautical miles. The VOR (VHF Omnidirectional Range) navigational aid achieves different service volumes based on the altitude of the aircraft. For an aircraft operating at higher altitudes, the effective range of a VOR increases due to the line-of-sight nature of radio signals and the curvature of the Earth. At altitudes above 45,000 feet and up to 60,000 feet, pilots can expect reliable navigation services from VOR stations extending out to 100 nautical miles, which is critical for en route navigation and maintaining situational awareness in the airspace. Other service volumes at lower altitudes do not apply in this case, which is why the correct range specified aligns with the operational parameters for VORs at higher flight levels.
