When sailing upwind, the relative speed of the wind on the sails is greater than the actual speed of the wind and this relative wind creates a larger force on the sails that can push sailboats faster than the actual wind speed.
If an anemometer is installed' on board, the instrument on the bridge shall display the relative wind speed and direction.
This mechanical quantity is the product of the absolute wind speed, the sum of the Earth’s speed and the relative wind speed with respect to the Earth, by the distance to the Earth’s axis.
As the aircraft went beyond its design envelope, the nose simply flopped over pointing earthwards – with a few small turns the airspeed picked up.
