Aircraft flight testing is an extended branch of aerospace science and its development is closely related to the increasing requirements of the traffic safety. Contemporary the prototype flight testing of a small aircraft does not include a flight measurement with a data recording because the cost of these measurements is not acceptable for companies building these kinds of aircraft. The result of this flight measurement is a data file containing very useful aircraft information for a designer. Knowledge of the flight behaviour and flight loads of a sport aircraft, a glider or an ultralight has got a positive influence on sport flying and soaring safety. Looking on all the special requirements for small aircraft flight testing the development of a new portable data acquisition system (DAS 12) was started at the Institute of Aerospace Engineering of Brno University of Technology with the collaboration with Mesit ltd. The system should fully satisfy all the requirements. DAS 12 is digital twelve-channel mobile data acquisition system dedicated for strain gauges measurements, pressure measurements, temperature and other analogue variable measurement. Data acquisition system is created together with a sensor set. The sensors capture the movement of the aircraft from rolling until the landing.
