In fixed-wing aircraft, apparent wind is what is experienced on-board and it determines the necessary speeds for take-off and landing. Aircraft carriers generally steam directly upwind at maximum speed, in order to increase apparent wind and reduce the necessary take-off velocity. Land-based airport traffic, as well as most mid-sized and large birds generally take off and land facing upwind for the same reason.
