The airplane can land using crab only (zero side slip) up to the landing crosswind guideline. On dry runways, upon touchdown the airplane tracks towards the upwind edge of the runway while de-crabbing to align with the runway. Immediate upwind aileron is needed to ensure the wings remain level while rudder is needed to track center line.
The NTSB also received a report analyzing 250,327 departures involving 737-500s and found that only four of those departures (less than 0.002%) had experienced a crosswind above 30 knots (56 km/h; 35 mph), [4] meaning that for a commercial pilot to have real-life experience with crosswinds anywhere near the velocity that hit Continental ...
Light aircraft landing situations, and the pilot skills required, can be divided into four types: Normal landings [4] Crosswind landings - where a significant wind not aligned with the landing area is a factor [4] Short field landings - where the length of the landing area is a limiting factor [4]
Figure 1. Plots of quadratic function y = ax 2 + bx + c, varying each coefficient separately while the other coefficients are fixed (at values a = 1, b = 0, c = 0). A quadratic equation whose coefficients are real numbers can have either zero, one, or two distinct real-valued solutions, also called roots.
The risk for wingstrike primarily depends on the angle of the line between the tip of the wing and the landing gear. The position of the landing gear, when calculating that line, should be at the point that it is maximally compressed, for example if the aircraft comes down off center and with its weight entirely on the downwind gear.
The crosswind component is computed by multiplying the wind speed by the sine of the angle between the wind and the direction of travel while the headwind component is computed in the same manner, using cosine instead of sine. For example, a 10 knot wind coming at 45 degrees from either side will have a crosswind component of 10 knots × sin(45 ...

The quadratic programming problem with n variables and m constraints can be formulated as follows. [2] Given: a real-valued, n-dimensional vector c, an n×n-dimensional real symmetric matrix Q, an m×n-dimensional real matrix A, and; an m-dimensional real vector b, the objective of quadratic programming is to find an n-dimensional vector x ...
