However, one major deviation of the proposed rule from standard J2263 is that the terrestrial wind velocity measured by track-based anemometers at vehicle mid-height is used to "calibrate" the vehicle-mounted anemometer sensing the apparent wind at a different height.
It uses apparent wind, or the sail wind, to generate pull in much the same way that an airplane will take off when it reaches a certain speed.
Crosswind systems rely on high-speed periodic motions of a tethered wing to obtain a much greater apparent wind speed than the absolute wind relative to the ground.
Similarly, huge wind potential is expected associated with the Pakistan coastal belt considering its length and apparent wind trends (Zaigham and Nayyar, 2005; Nayyar, 2009).

Outdoor enthusiasts who create their own wind or increase the existing wind--by skiing, snowmobiling, or running for example--can increase the apparent wind chill.
Unlike traditional wind sensors, the GWS 10 serves as a mini weather station, providing barometric pressure and air temperature data in addition to apparent wind and pressure trend data.
The Assisted Sail Trim consists of three OEM packages that offer sensor-guided, push-button sail control operated from a cockpit display: The Auto-Tacking base package adjusts the headsail for the new tack while you steer through the maneuver; The Auto Trim is the perfect complement to Auto Tacking letting you set the initial trim and press the button to engage Auto Trim so the system can monitor apparent wind for perfect sail trim.
The SailRocket 2 featured three pods that helped lift the craft out of the water at speed and a fuselage that pointed not in the direction of travel but into the apparent wind to cut down wind resistance.
