AVIATION & AERONAUTIC CALCULATOR
Wind Triangle
A precise tool.
What is the Wind Triangle & How does it work?
The wind triangle is a graphical representation used in aviation to determine the groundspeed and track of an aircraft given its true airspeed (TAS) and the wind conditions. It involves three vectors: the true course vector, the wind vector, and the resulting groundspeed vector.
text{Groundspeed} = sqrt{(V_{GS})^2 + (W)^2 + 2 cdot V_{GS} cdot W cdot cos(theta)}
VGS = Groundspeed, W = Wind speed, theta = Angle between TAS and wind direction
The track angle can be calculated using the law of sines or cosines, depending on the available information.

Frequently Asked Questions
What is a wind triangle in aviation?
A wind triangle is a graphical method used to determine an aircraft’s groundspeed and track by considering its true airspeed, wind speed, and the angle between them.
How do you calculate groundspeed using the wind triangle?
Groundspeed is calculated using the formula: Groundspeed = β(TASΒ² + Wind SpeedΒ² + 2 * TAS * Wind Speed * cos(ΞΈ)), where ΞΈ is the angle between true airspeed and wind direction.
What does the track angle represent in aviation?
The track angle represents the actual path an aircraft follows over the ground, taking into account both its heading and the wind’s effect.
Can you explain how to use this calculator for a flight planning scenario?
Input your true airspeed, wind speed, and the angle between them. The calculator will provide your groundspeed and track angle, aiding in flight planning.
What is the difference between true course and track in aviation?
True course is the intended heading of an aircraft relative to magnetic north, while track is the actual path it follows over the ground, influenced by wind.
How does wind affect an aircraft’s groundspeed?
Wind can increase or decrease groundspeed depending on its direction and speed relative to the aircraft’s heading. A headwind decreases groundspeed, while a tailwind increases it.
Is this calculator useful for pilots during flight?
Yes, this calculator is invaluable for pilots to adjust their course and plan routes based on real-time wind conditions to achieve the desired groundspeed and track.
