Abstract
A method and device of measuring external flight characteristics of aircraft, including fixed-wing, rotorcraft, and Unmanned Aerial Vehicles, utilizes one or more floating platforms, each supporting one or more measuring instruments. The floating platform may be a hot air balloon, dirigible or other quasi-neutrally-buoyant airship, untethered to avoid interference between the aircraft being measured and any tether. Measurement of rotorcraft acoustic characteristics is particularly enhanced by permitting measurements that account for directionality of noise sources and are not affected by wind or reflected noise.
