Estimation of Wind from Airplane States in Coordinated Flight

A e lter is dee ned that extracts the wind aloft from the Earth velocity and the orientation of a e ight vehicle in coordinated e ight (data that are available in the context of distributed interactive simulation ). A convergence theorem is proved stating that the estimated wind monotonically approaches the true wind when the latter is horizontal and constant. The e lter builds the transverse component of the wind and converges to the full wind as the e ight vehicle changes heading. The fastest convergence occurs when the e lter is applied at heading intervals equal to a critical interval that depends on the bank.
