If you have ever looked at an airplane coming in for landing in strong crosswinds, you know that even the biggest widebodies can wobble quite significantly during an approach.
If you are on board the flight, it may seem as if you are coming in almost sideways towards the runway. Why is that, and how do strong crosswinds actually affect aircraft landings?
Crosswind ‘crabbing’
Turbulence and bad weather can, to some extent, be avoided by altering the flight plan for much of the journey, but it is difficult to move an airport. Air traffic control will always try to direct planes so that they land into the wind.
