Assuming that the ground speed of an airplane is the air speed plus or minus The head or tail wind; how is the ground speed calculated when flying in a cross Wind (either at a right angle to the wind or on a diagonal course)?

Air Speed VS Ground Speed is described as speed through the air, plus or minus the Speed of the wind ( Head or Tail Wind). But how is this changed when flying in a Cross Wind?

How to convert wind speed to wind load

Hello there, I’m doing some research from wind energy and I now have problem. I have wind speed measurement from two sites with distance about 15 miles between them. One site have lot of holes in measurements and another site is complete. The question is: how can I do some correlation to fill holes...

A jet takes the same time to travel 2500 km %.555 with the wind as it does to travel 1900 km 2.555against the wind. If its speed relative to the air is 450 km/hr, what is the speed of the wind? I came up with a wind speed of 3 Km/hr Not sure how to put in a formula.
