A flow aligned device (12, 66, 100, 122, 150, 176, 214, 234) comprises a probe or vane (12, 66, 100, 122, 150, 176, 214, 234) that will sense angle of attack of an aircraft (10, 74, 106, 124, 164, 180, 210, 231). The flow aligned device (12, 66, 100, 122, 150, 176, 214, 234) is mounted about an axis (14, 116, 130, 156, 200, 220, 240) that is generally perpendicular to an aircraft, and includes pressure sensing ports for sensing pitot pressure (40A, 70, 170, 230, 246) and static pressure (48A, 73, 114, 144, 172) right on the vane (12, 66, 100, 150, 176, 214, 234). The trailing edge (34, 84, 108, 136, 166, 186, 218, 238) of the vane is inclined in a forward direction outwardly from the aircraft body to permit items that may be sliding along the aircraft body from the rear toward the front (e.g. air-to-air refueling baskets) to slide past the vane (12, 66, 100, 122, 150, 176, 214, 234) without being hooked or caught.
