Question
What is turbulence intensity for the mean wind speed of 6.5 m/s with astandard deviation of2.96 m/s?
Solution
Turbulence intensity is a measure of the intensity of turbulence in a fluid flow. It is defined as the ratio of the standard deviation of the wind speed to the mean wind speed.
Here's how to calculate it:
- Identify the mean wind speed. In this case, it's 6.5 m/s.
- Identify the standard deviation of the wind speed. In this case, it's 2.96 m/s.
- Divide the standard deviation by the mean wind speed.
So, the calculation would be:
Turbulence Intensity = (Standard Deviation / Mean Wind Speed) * 100%
= (2.96 m/s / 6.5 m/s) * 100%
= 0.455 * 100%
= 45.5%
So, the turbulence intensity for the mean wind speed of 6.5 m/s with a standard deviation of 2.96 m/s is 45.5%.

A pilot is estimating the flight time for a planned flight of 500 nautical miles based on the forecast wind at flight level. The expected wind speed along the flight route at flight level is a tailwind of 20 knots. The aircraft’s cruise speed (true airspeed) is 150 knots.The pilot determines that the ground speed will be knots, and that the estimated flight time is about hours.
