Abstract: A vane for dynamic flow angle measurements may have improved performance for time lag responsiveness over a prior art delta-shaped vane. In various embodiments, a gust sensing vane may have a cropped-delta shape and configured to align to a fluid flow direction, where the gust sensing vane comprises a forward portion having a leading edge and an aft portion having a first trailing edge and a second trailing edge. A cross-sectional area of the forward portion may have a triangular shape. Furthermore, a cross-sectional area of the aft portion has two substantially parallel sides to form the cropped-delta shape of the gust sensing vane. The gust sensing vane may be coupled to, and extend away from, a rotary hub.
