I wanted to ask this since very long time. Virtual cockpit zoom level seem to be fixed at 100% or less (10% steps) or 150% or more (50 or 100% steps). I would like to try a VC zoom level of 120 or 130% is this somehow possible?

Not at my flight system so I cannot check but I'd start by looking at the cameras.cfg fle for the VC definition. Possibly you can adjust the zoom level there.

Good idea.

Unfortunately it don't see any entries which would allow this?

There are a lot of options for camera definitions in the SDK here: http://www.prepar3d.com/SDKv5/sdk/cameras/camera_configuration.html

But I don't see one that adjusts the rate of zoom with the keyboard commands.

That said, the initial zoom on your VC is 0.3.  If you're thinking of that as 30% and you want to try 130%?  You could change the initial zoom to 1.3, but I think that might make the VC unusable (too zoomed in).  But...you could experiment with the initial zoom in tighter increments to try and find what you're looking for.  You can make the change to the file and then use, I believe Shift-F10 to reload the aircraft and try?  If you don't have that setup by default, you can assign a keyboard command to "Reload User Object" in the controls menu.

There are default key commands that will increase/decrease the zoom in smaller increments.  I changed mine so I'm not sure what the default is.  If you look in the controls tab I think it's labeled "Selection Increase (slightly)" or something to that affect.  This will zoom at a consistent 1% step.  Sorry, I'm not at my Sim.  I can check later if you hadn't figured it out.  

Hold down the SHIFT key when pressing -/=.

That was too easy 😉  Thanks a lot.
