A plane cannot typically take off when winds speeds going from side to side or crosswinds, exceed 35 knots. Consistent winds in excess of 50 knots will shut down most airport operations. A plane cannot typically take off when winds speeds going from side to side or crosswinds, exceed 35 knots.
A plane's ability to get off the ground depends on four main forces and how they interact with each other. These four forces are thrust, drag, lift, and weight. Thrust is the force created by the plane's engine that pushes it forward. It is similar to the force of a car's engine pushing the car down the road. Drag is the force of the wind pushing back on the plane. Airplanes must contend with the force of drag whether or not it is a windy day because, even on a still day, the effect of air movement is created as the plane flies through the air. Drag pushes the plane in the opposite direction from the direction of thrust.
