now i think i'm on the right way with this bird, but i have a few more questions for this community.

First of all is the panel state after loading, on my Captain Sim .save file (cold and dark) the whole cockpit is not really cold and dark, for example fuel pumps are all on, engine bleed and ac pack is on, hydraulic systems A + B are on. So i decided to shut everything off and save. Exiting FSX and reloading previously saved flight my  panel state return like first one 
is there a trick to save a really cold and dark panel?

Second one is fuel dump, i can start dumping only tank n°1 , when tank 1 is empty the 3rd tank will start. is this possible? how config to dump tank n° 1 and 3 to 50%?

Cabine pressure is my last question, when climbing with mode selector knob set to auto sometimes pressure will decrease  , is cabine altitude really working on CS 727 or only a fake?

about panel state - now load "cleared for takeoff" flight for that aircraft, and then load your cold and dark flight twice. You'll see that some switches state mixed So that problem stays.

Cant tell for fuel dump, never used it.

Pressurization system doesnt works in cs 727. We all hoping for CS to fix it in future.

ok, thanks

Im using it on 727. it works not like in 707, but it works! It really important if you want to use addons like FSPX with pressurization option enabled. If you just fly 727 - it not so important.
