During the development of the aircraft structure, test flights are indispensible. In some experiments additional sensors are mounted, which often leads to certain technical problem. In particular, changes of the structure are necessary and additional costs are generated. Therefore, advanced measurement methods enabling an analysis of several parameters without adding special sensors are developed. One of the projects focused on problems of measurement during the flight is the AIM2 project in the frames of FP7. During research mobile optical measurement systems and application rules are developed As described in references [1, 2], the AIM project - Advanced In-flight Measurement Techniques – focused on the application of modern optical measurement techniques in industrial wind tunnels for the purpose of flight testing. Possibilities to measure wing and rotor deformation, surface pressu re distribution, heat distribution and flow velocity fields in a non-intrusive way and with a minimal sensor setup were presented in the AIM project. Also, the most important challenges connected with industrial implementation of methods demonstrated in the AIM project were taken into consideration. The research is being continued in AIM² project. AIM2 aims at the development of measurement methods for easy and typical applications to in-flight testing with industrial requirements. In order to test the optical measurement methods, additional flight data are required. The data required are angular rates in the body frame, Euler angles, accelerations, IAS, TAS, altitude. This article describes a system which is used in the project for additional data measurements. The whole system will be mounted on the board of the PW-6 glider.
