Installation:
1) Copy the folder "URRR_Rostov_on_Don" to the simulator folder \FSX\Addon Scenery\.
2) Copy files "Jetstream_Light_splash_effect.fx", "Jetstream_Light_splash_effect2.fx" and "Jetstream_Light_splash_effect3.fx" from the \Effects\ folder to the simulator folder \FSX\effects\.
3) Copy the file "JDS_rmplight.bmp" from the \Effects\ folder to the simulator folder \FSX\effects\texture\ folder.

Seasons change: 
The summer vegetation is installed by default.
There are seasonal vegetation BGL files in the \Seasons\ folder :
- URRR_vegetation_SU.bgl - Summer
- URRR_vegetation_FA.bgl - Autumn
- URRR_vegetation_WI.bgl - Winter
- URRR_vegetation_HW.bgl - Snowy Winter
- URRR_vegetation_SP.bgl - Spring
In order to change a season just copy the desired BGL to the URRR_Rostov_on_Don\Scenery folder. Do not forget to delete the previous season.
The change of seasons could have been programmed in SODE, but I do not want to get involved with copyrights (extracting MDL's from BGL's).

Static models:
The file URRR_Static_Planes.bgl: Il-76, Yak-40, Mi-8 as well as two Tu-134's (at the aircraft plant and on the SW apron extremity) and An-8 (the parkings for them are reserved).
File URRR_Static_Ground_Vehicles.bgl: vehicles and ladders.
If you do not need the static models, you can delete those files.
The following static models were used with thanks to their autors:
- An-8 and Yak-40 D.Samborsky (repaint by Vantenzin Maxim and Andrei Maslov)
- Mi-8T helicopter of Dmitry Shnurov
- IL-76 of Varnavsky Sergey (repaint by Rubek (rubek@sarkor.uz)
- Tu-134 from Victor Stolpiansky
- Tu-154 from Victor Shacht (repaint by Igor Fedorov aka OK-DGL)

Also many thanks to Thomas32 from FSDeveloper forum for his perfect light effect.
