I have been looking and almost found the answer I was looking for but to no avail.

KMSP.  The Clear Weather no wind default startup runway is runway 4.  How can I get changed to something else?  I know and understand about changing winds around and all that.  I meas how do I edit the airport to have the runway default change.  What file is it in if anyone knows?  I would appreciate it.

You didn't mention which sim your using...I'll guess FSX.

The sim (FS2004 and FSX) uses a complex scoring process the determine the clear weather active runway. There is no 'simple' way to change the clear weather active. If you're interested, Jim Vile (jvile01) discusses it in this external forum.

For FSX, Jim Vile created an excellnt airport update for KMSP. 17/35 is in use (it's under construction in the FSX default.) Clear weather active runways now are the parellel 12/30's and 17/35. They are used simultaneously when conditions allow. 4/20 is only used when conditions dictate.

Additionally: new taxiways, updated parking with ai parking codes, improved taxi routes for smoother flow, GPS PROCedural approaches for 17/35, and nice scenery enhancements.

I could not find the download here at SimV. It can be found at Avsim, search for file kmsp_ade_jv.zip by Jim Vile.

Note: When you tune ATIS you may hear several runways listed that don't exist at the airport. This is fallout from the 'crosswind runway technique' Jim uses as part of the process to change the clear weather active. It can't be avoided and is only a minor distraction.
