The Rogozarski SIM-VI (Рогожарски СИМ-VI in Serbian) was a single-engined, two-seat one low wing aircraft designed as trainer in Yugoslavia before World War II. It was designed and built at the Rogožarski factory in Belgrade.

Aircraft SIM-VI was designed by engineer Sima Milutinovic early 1930's in order to make easy and inexpensive in operation for airplane pilot training that would allow an easier presentation and massification of sports aviation. This project is all lying in the drawer until 1936, when conditions have been met to create a prototype of the aircraft. The prototype was made in a factory Rogožarski first test flight took place on the 1937th. The plane was low wing monoplane with a four cylinder, Walter Mikron power of 50 hp, double-blad wooden propeller, with two crew members who were seated in a tandem arrangement, one after another. The plane that is intended for civilian use, sport pilot training, demonstration flights and travel [1]. The plane was a wooden structure covered with textil The wings are thin profile of only 6% of trapezoidal shape with rounded ends. On each side, the wings were stretched molded wire ties.
After successful testing and registration (YU-PDX)[2] plane SIM-VI has bought Central Administration Aero Club, which used him at rallies and aviation training sport pilots. The serial production of aircraft has not entered because he could not use the smaller and under-equipped airports that have usually been in the countryside.
In flight tests that were carried out at the airport in Zemun has shown that the plane SIM-VI-a has a slightly better performance than its predecessor, it is unlike him and unable to perform basic stunts. After receiving a navigation license is a registered civil aircraft markings YU-PEZ[3] and it was bought by Central Administration Aero Club. The plane was used until the beginning of the war, the 1941st at the air rallies, the trenažu pilots and sports competitions. Pilot Eng. Arsenijevic, participated in this plane the circular flight sportsmen sports plane through the state Small Atante 1938th The stages at which time he flew 3274 km achieving an average speed of 151.01 km/h. Pilots who flew the plane felt that the plane is agile and easy to handle and fly, but in addition to good features and relatively low cost SIM-VI is not done in the series because he could not beat a traditional, empirical approach (robust and powerful aircraft is a good plane). On the eve of the war, the aircraft was included on Yugoslav Air Force and used as liaison aircraft, were destroyed during the bombing war airport Lazarevac 7 April 1941 year.
Immediately after completing the flight test aircraft SIM-VI, engineer Milutinovic to accept the observed shortcomings, so that by the end of the 1937th Rogozarski made in a new variant of this airplane was designated the SIM-VI-a. Compared to its predecessor, this plane is different before everything that had built something more powerful engine Walter Mikron II power of 44kW (60hp that is). Increasing the engine power required is to strengthen the basic structure as the aircraft engineer. Milutinovic used for general improvement of the aircraft. Namely, the plane SIM-VI is increased relative thickness of the wing with 6% to 15% so because of the increased strength of the wings removed and wire ties to half of the wing was covered with cardboard swing instead of cloth which has improved the overall stiffness of the aircraft. It has also enabled improved landing gear and aerodynamic characteristics of new aircraft, while his weight slightly increased.
