I tried several times to land at KCOS RC give me descend maintain 12000 until established on the localized. This is too high on wry 35l or 17L the chart calls for 8000 so which would I use to land

Way too high. Ignore it and fly in at the actual intercept altitude.

RWY 17 shows an initial approach altitude of 10,000 which is not too far off. You might try refreshing/reloading the FSX data base in RC. Once RC gives you the descend to altitude until established, it has been my experience that you can go ahead and fly the approach as shown on the approach plates without being gigged by RC.

What is the MSA set to in the Controller section?

There is high ground to the west of this airport. Did you select NOTAMS for the arrival? If you do you will be cleared lower at your discretion. Not selecting NOTAMS will keep you high to avoid nearby terrain.

Then that may be the problem I didn't check NOTAMS I forget when going into mountain areas I have no problem at KDEN just here at KCOS

You might wish to look at the only STAR listed:

to clear terrain at the indicated paths and altitudes. The ILS IAP charts are:

and

On the STAR the darker lines indicate your choice of approach paths. The one that satisfies your arrival direction provides the waypoints to go into your flight plan for RC. All paths include the BRK VOR which is not a fly over point but is the base for a DME ARC navigation point on both approaches. Read the description at the chart bottom for the arrival transition point you select.

 

All paths lead to FSHER south of the airport about 30 nm and can be flown at 9000. As you head toward BRK though the minimum is 9000 and you will start getting vectors just about at FSHER as you head toward BRK. If you aircraft has an FMC or GPS with approach procedures you can in RC select an IAP approach which lets you do your own navigation in lieu of vectors, or you can take the vectors. Either way, use NOTAMS as suggested.

 

FSHER is common to all STAR arrivals so that is safe to put in your flight plan sent to RC along with the most convenient transition path. As a crossover waypoint BRK will be ignored.

 

The intercept for 17L at MOGAL is at 10,000 feet and occurs about 15 nm from the runway, about what RC may use for the intercept point. For 35R RC would intercept the localizer around FALUR which has a minimum or 8,500 feet but is flat to CEGIX which the GS intercept at 8,500 so you can get to FALUR at a higher altitude.

 

Now, RC4 does not know about directional altitude constraints so dynamic runway assignment to put in the IAF points for a known runway here might be a problem. So once the runway is assigned acknowledge the first vector and then choose the IAP approach version and fly from the charts to get on the intercept. Hopefully you nav gear has the procedure. The object is to avoid RC vectoring you into a pattern west of the runway alignment.

 

In the RC43 manual look up the IAP procedure as well as NOTAMS.

 

Here is a tip sheet for using add-on planners that lets you modify a plan before exporting to an FS format to be sent to RC:

It depends on how far away the high ground is. But not checking NOTAMS will definitely give you problems. As Ron say's, RC4 doesn't know which direction the high ground is so it plays safe.

 

We got as far as identifying the high ground direction in RC5 but the future of that remains uncertain.

airtran, also realize KCOS is a lot closer to the mountains than KDEN. A lot closer.
