AVIATION & AERONAUTIC CALCULATOR
Vor Range
A precise tool.
What is the Vor Range & How does it work?
A VOR (VHF Omnidirectional Range) is a type of ground-based navigation system used in aviation to determine the bearing, distance, and track of an aircraft relative to a fixed point on the ground.
The reception range of a VOR signal is influenced by various factors including altitude, terrain, and atmospheric conditions. Generally, the line-of-sight (LOS) range for a VOR receiver increases with altitude due to fewer obstructions.
R = sqrt{2h_1h_2} + h_1 + h_2
R = Reception range in nautical miles, h_1 = Altitude of the VOR station in feet, h_2 = Altitude of the aircraft in feet

Frequently Asked Questions
What is a VOR in aviation?
A VOR, or VHF Omnidirectional Range, is a ground-based navigation system used to determine the bearing, distance, and track of an aircraft relative to a fixed point on the ground.
How does altitude affect VOR reception range?
The line-of-sight (LOS) range for a VOR receiver increases with altitude due to fewer obstructions. Higher altitudes generally result in a longer reception range.
What factors influence the VOR signal reception range?
Various factors including altitude, terrain, and atmospheric conditions influence the reception range of a VOR signal.
How do I calculate the VOR reception range?
The formula to calculate the VOR reception range is R = √(2h1h2) + h1 + h2, where R is the reception range in nautical miles and h1 and h2 are the heights of the transmitting and receiving antennas.
Can atmospheric conditions affect VOR reception?
Yes, atmospheric conditions such as temperature inversions or precipitation can affect the propagation of VOR signals, potentially reducing the reception range.
What is the typical line-of-sight range for a VOR receiver at sea level?
The typical line-of-sight range for a VOR receiver at sea level is around 200 nautical miles under ideal conditions, but this can vary based on terrain and atmospheric factors.
How does terrain impact the reception of VOR signals?
Terrain can significantly impact VOR signal reception by obstructing line-of-sight paths. Mountains or other elevated obstacles can block or weaken the signal, reducing the effective range.
