A couple of months ago I had the urge to fly some Russian aircraft. Below a few images of those flights. Unfortunately I do not recall the departure or arrival airports for those flights. My main aim is to focus on the aircraft and airlines operating them.
OK....for the TU-154 I downloaded from flightsim the following or just go on their website and search for TU-154.
ptu_154fsx.zip and tupolev_tu-154_b2. The panels are part of the aircraft for FSX.
For the TU-134 I downloaded several aircraft some were for FS2004 and I did a port over to FSX and then you can download 1tu134.zip which is a Viking Air (fictional) FSX TU-134 and use the panel that comes with it or alternatively use an early 737 panel which worked good for me also.
