For pilots we offer the possibility of comparing of two very important angles of view. The first is the comparison of the two different power units already mentioned, and the other is the comparison of flight characteristics of conventional “flex” wings and ATOS rigid wings. Typically, we have different types and sizes of wings at the airport, where you can practically test the full range of flight characteristics. Very interesting is testing of the use of various levels of control elements, including air brakes. Brakes are the greatest safety benefit for powered flying. By using the brakes, the less experienced pilot is able to accurately correct his landing approach and land safely on very small areas.
