bleeds / Air conditioning question

[Chase911]

First off let me say that i fly a lot of various models in XP. And i have to admit that this airplane is the most fun airplane for me. The sounds and attention to detail is just wonderful.

Ok my question is more of a procedural question. Is there really a point in resetting the bleeds and turning on both recirculating fans to supply air conditioning to the passenger compartment prior to engine start? Sure you can certainly get some air moving around but the air won't actually cool until after engine start right?

I see in several YouTube videos people turn on those fans befor start then again after start they reset the bleeds. I don't see the reasoning behind this,  unless it has something to do with the actual starting of the engines. 

I've been just waiting until after start to turn on the fans and bleeds   seams to start ok without them on. For realism I'd like to know how it's done in real world settings. 

2nd question: I've searched the forums without locating an answer...  Is there a way to bind the flaps to an axis  control? Right now I'm having to use the 3d handle in the cockpit. No biggy if it can't be done. 

Thanks,

Dave
