What is the maximum crosswind component that a Boeing 737-800 can take off and land in? The Boeing 737-800 has a demonstrated crosswind limitation of approximately 33 knots, or roughly 38 miles per hour.
For example, the Boeing 737 has a maximum crosswind landing factor of 30 knots (just over 55 mph). So that answers the second part of your question. Yes, a 'plane can land in 50 mph winds.
There is no single maximum wind speed that cancels flights, as it depends on the direction of wind and phase of flight. A crosswind above about 40mph and a tailwind above 10mph can start to cause problems and stop commercial jets from taking off and landing.
Wind speed and direction – key parameters for flight safetyDuring take-offs and landings, wind speed higher than 30 KT (approximately 55 km/h) is considered dangerous. Most communication airports indicate this value as a criterion for issuing an airport warning, distinguishing between the mean wind speed and gusts.
Other special cases include a tailwind, where the plane and wind are acting in the same direction. As you may suspect, the speed of the aircraft increases when there is a tailwind and decreases when there is a headwind.
That flight set a record for the fastest subsonic transatlantic commercial airline flight — 5 hours and 13 minutes, thanks to a 202 mph tailwind. For reference, the speed of sound is 760 mph; but the plane did not break the sound barrier.
There is no single maximum wind limit as it depends on the direction of wind and phase of flight. A crosswind above about 40mph and tailwind above 10mph can start to cause problems and stop commercial jets taking off and landing. It can sometimes be too windy to take-off or land.
The Federal Aviation Administration (FAA) has set guidelines for crosswind limits, which vary depending on the type and size of the plane. In general, commercial airlines are designed to handle crosswinds up to 30-40 knots (approximately 35-46 mph), and some planes are capable of landing in even higher winds.
During take off and landing, tailwinds ireduce the airflow. Consequently, the necessary lift is achieved later and at higher speeds (the wind speed is added to the aircraft speed). Therefore, longer runways are required to perform a safe take off or landing.
Because headwind increases the lift, pilots prefer to land and take off in headwind. Tailwind is wind blowing from behind the aircraft. It reduces the lift and aircraft generally avoid taking off or landing in tailwind.
Even a bit of tailwind can be a hazard. Tailwind conditions can have adverse effects on aircraft performance and handling qualities in the critical flight phases of takeoff, approach and landing. Tailwind, for instance, increases the required runway length to land on or takeoff from.
There is no headwind limitation for most commercial aircraft for take-off, and therefore is no maximum overall limit for take-off (or landing). If there was a 100mph wind, all of which was a headwind component, in theory the aircraft wouldn't be restricted from taking off.
