Because temperature The numbers are averages of most the years that their airport weather stations have collected data. A peer-review published article titled 30,000-foot-level Performance Metric Reporting by Forrest Breyfogle describes the reporting of measurements from an in-flight airplane point of view. Wind speeds over 99 knots are extracted by subtracting 50 from the direction and adding 100 to the speed. Wind speeds over 99 knots are extracted by subtracting 50 from the direction and adding 100 to the speed. That's even higher than any of the wind speeds measured over these last few days. Doug Morris, a captain with Air Canada, explains that the general rule is the higher the better "because the thinner air imposes less drag". The maps also indicate two components of wind direction: U-wind represents the east-west component of wind and V-wind represents the north-south component. Contacts.

"Concorde flew at much higher altitudes 50,000/60,000 feet where there were no other aircraft and so were able to cruise climb [that is keep climbing].". Find the difference in speed between a flight without wind (200km/h) and with the wind (250km/h): 250km/h - 200km/h = 50km/h. Since wind speeds tend to be pretty variable over time, I assume this would give the most accurate wind speed for the most important flight regime.
