1. A method for designing an aircraft comprising: providing a model of the aircraft and a plurality of sensors mounted on the aircraft model; positioning the aircraft model in a fluid tunnel at an initial attitude; measuring an initial orientation of the aircraft model while the aircraft model is at the initial attitude using a first tilt sensor of said sensors to create initial orientation information; passing fluid over the aircraft model using the fluid tunnel; actively moving the aircraft model from the initial attitude to a subsequent attitude; and measuring a subsequent orientation of the aircraft model while the aircraft model is at the subsequent attitude using a first orientation sensor of said sensors to create subsequent orientation information.
