Question: What does the term “demonstrated crosswind component” mean? I just started flight training, and the flight school aircraft have placards that read “maximum demonstrated crosswind velocity 15 knots.” Does that mean I can’t fly when the winds are above 15 knots?
Answer: The demonstrated crosswind component is the maximum velocity of the crosswind component that was experienced during the certification tests, and the pilots were still able to maintain adequate control of the aircraft. Most aircraft that have a placard like that often have an additional line in smaller type that reads “not a limitation.”
The aircraft, depending on pilot technique, could be more. For more information on operating in crosswinds, check out the Airplane Flying Handbook (FAA-H-8083-3A), which lists common errors pilots make during crosswind takeoffs and landings and ways to mitigate them.
If you’re trying to land and you “run out of rudder”—a phrase meaning you can’t keep the airplane lined up in the centerline during landing because the wind is so strong—you’ve just found the limitation. Find a runway that is more aligned with the prevailing wind.
