This paper discusses development of a technique to obtain smoothed airdata during wake penetrations and atmospheric disturbances encountered by a high-performance aircraft. The technique uses MIL (Military) grade rate and acceleration sensors and airdata sensors within the Digital Flight Control Computer. The paper includes a novel method of estimating inertial velocities from 3 axis linear accelerations without any dependence on GPS, which can be used for filtering out wake effects, gusts and turbulence effects on airdata sensors, while retaining good bandwidth. The technique has been extensively evaluated using flight test data of a high-performance aircraft and it has yielded promising results.
