Commercial use of our products


Drzewiecki Design products are sold with licences which do not grant a permission for any commercial use. In order to use our products on commercial stations (no matter if for entertainment or for flight training) a commercial licence must be purchased and an agreement must be signed by both parties. If these requirements are not met, using our software during commercial operations is not legal. You are allowed to use our products for tests though.


Prices of our commercial licences are different for the entertainment and the professional market:

  • Commercial Entertainment license price per product per station = the price of 1h of flight on that station (for general customers). We have a lot of scenic locations loved by entertainment users of non-certified flight simulators.

  • Commercial Professional (EASA/FAA certified station for training) license price per product per station = 1000eur incl. tax . Our products are used on numerous certified stations and provide a very good performance and a very high realism for VFR/IFR operations training.

Prices may be subject to negotiations and barter agreement can be arranged, depending on what can be offered to us in exchange.


Please note - our requirement for any commercial use is to be able to test the platform at least 2h annually for free to ensure best performance of our products.


Each commercial agreement is constructed individually. To get more information please contact us directly:




Individual orders of scenery related products


Individual orders of customer-defined, flight simulator scenery-related products can be made. Our products can be compatible with Microsoft Flight Simulator 2004, Microsoft Flight Simulator X, Flight Simulator X Steam Edition, Dovetail Games Flight Sim World, Lockheed Martin Prepar3D (all versions) and Laminar Research X-Plane 10/11. We are able to create 3D models of any parts of the real world - from tiny airstrips to huge metropolitan areas with thousands of custom-made buildings.


Thanks to our know-how in advanced modeling, texturing and specialized programming techniques we can achieve exceptionally realistic renderings of parts of the real world in flight simulators. With our products not only is IFR local procedure training possible but also detailed familiarization with airport layouts and VFR training with all distinctive ground objects perfectly recognizable. We provide leading solutions for the flight simulation market and our products are successfully used in professional flight training on FAA/EASA certified platforms.


Prices of customer-defined products depend on the amount of detail required. We calculate 10.000 euros net per month of work. A price of a very small airstrip or heliport would be around 1000 euros (we rarely work on this type of projects though) while large metropolian areas or complex military/commercial airports would cost >30.000 euros, depending on the time required to complete the project. All prices are calculated individually.


Please take into account that we work on various projects all the time and we plan our next releases 1-2 years ahead. Although developing a small airfield might take 1-2 weeks, producing a model of a large airport or a city can take up to a year. For more info please contact us at:
