AVIATION & AERONAUTIC CALCULATOR
Vor Radial Crossing
A precise tool.
What is the Vor Radial Crossing & How does it work?
The Vor Radial Crossing calculator is used to determine the time it takes for an aircraft to cross a VOR (VHF Omnidirectional Range) radial. This calculation is essential for flight planning and navigation, ensuring that pilots can accurately predict their arrival times at specific points along their route.
t = frac{d}{v cdot cos(theta)}
t = time to cross the radial, d = distance from the VOR to the crossing point, v = groundspeed of the aircraft, theta = angle between the course and the radial.
The formula accounts for the component of the aircraft’s velocity that is perpendicular to the radial. By using the cosine of the angle (theta), we determine how much of the groundspeed contributes to crossing the radial directly.

Frequently Asked Questions
How do I use the Vor Radial Crossing calculator?
Enter the distance from the VOR to the crossing point, the aircraft’s groundspeed, and the angle between the course and the radial. The calculator will provide the time to cross.
What is a VOR in aviation?
A VOR (VHF Omnidirectional Range) is a type of navigation aid that provides aircraft with direction information relative to a fixed point on the ground.
Why is knowing the time to cross a radial important for pilots?
It helps in accurate flight planning and navigation, ensuring pilots can predict their arrival times at specific points along their route.
What does the angle between the course and the radial represent?
It represents the difference in direction between the aircraft’s current heading and the VOR radial line it is crossing.
Can this calculator be used for any type of aircraft?
Yes, as long as you have the necessary data such as groundspeed and angle, the calculator can be used for various types of aircraft.
What units should I use when entering the values into the calculator?
Typically, distance is in nautical miles, groundspeed in knots, and angle in degrees.
How accurate is this calculation?
The accuracy depends on the precision of the input data. It provides a good estimate but should be used in conjunction with other navigation tools for precise flight planning.
