Aerospace and Aircraft Design Alpina D-DSNB Private Airplane by Hakan Gürsu This plane is designed for 4 people’s usage. Because of being able to land and take off in short distances, it can be used in mountainous area where there is a lot of altitude differences. Also, half wings under the main ones provide more balanced gliding. The supporting parts between the main and half wings supply more stability to the main wings. Furthermore, it is lightweight and has a spacious interior design thanks to perforated seating units and high-top glass cover.
