AVIATION & AERONAUTIC CALCULATOR
Vor Cone Of Silence
A precise tool.
What is the Vor Cone Of Silence & How does it work?
A VOR (VHF Omnidirectional Range) is a type of navigation aid used in aviation to provide pilots with the bearing, but not the distance, from the aircraft to a fixed ground transmitter. The VOR cone of silence refers to the area around the VOR station where the signal is weakest and unreliable.
The radius of the VOR cone of silence varies with altitude. At lower altitudes, the cone is wider due to atmospheric conditions affecting signal propagation. As altitude increases, the cone narrows because the signal travels in a more direct path through the atmosphere.
R = frac{h}{tan(theta)} + h
R = Radius of the cone of silence, h = Altitude above ground level, theta = Cone angle

Frequently Asked Questions
What is a VOR cone of silence?
The VOR cone of silence is an area around a VOR station where the signal is weakest and unreliable, affecting aircraft navigation.
How does the VOR cone of silence change with altitude?
At lower altitudes, the VOR cone of silence is wider due to atmospheric conditions. As altitude increases, the cone narrows because signals propagate more directly through thinner air.
What factors affect the width of the VOR cone of silence at low altitudes?
Atmospheric conditions such as temperature and humidity can affect how radio waves propagate, making the VOR cone wider at lower altitudes.
How does the VOR cone of silence impact aviation safety?
The VOR cone of silence can impact aviation safety by providing unreliable navigation information to pilots in certain areas around the VOR station.
Can I use this calculator for any altitude?
Yes, you can input various altitudes to calculate the corresponding radius of the VOR cone of silence at different heights above ground level.
