Wind direction on an aircraft carrier
In order for a carrier to head into the wind (or any ship for that matter) for the purposes of aircraft operations, what do they use to tell the wind direction? Apparently, a carrier can sail at 30 - 35 knots which causes a pretty decent "wind" relative to the deck. What device is used to separate the natural wind direction and speed relative to the direction and speed of the ship? I doubt that putting a wrought iron rooster up on the mast with an arrow and NSEW arms will work!
