This is just a preliminary question to help see where I might be going wrong.I am flying the LDS767 into the new and really very good and very reasonably priced SEQU Quito scenery by Boris Forero (landing elevation 9230 and surrounded by big bits of solid rock, up to 15,900ft paralel to the airport) and twice RC has driven me into the hillside.I am using a plan (SBFZ-SEQU) provided by FS Commander, the QNH is set according to the controllers instructions and they seem to be happy with my altitude, but twice now (origonal flight and pickup from saved .rcd) has given me unflyable (driveable maybe, in a 4x4) instructions whilst descending me from my cruise at FL340 to FL150.I was wondering what RC knows about scenery altitude. I have had FS Global installed for ages so RC knows about that, and after installing the new scenery I ran both the the FSC and RC databases so in theory everything should tally.Any ideas? Am I missing something basic here?

Ok, I nailed it this time, so it was pilot error - descending too slowly, prolly, but it is scary wheels-scraping-the-terrain stuff.So just to simplify my enquiry - what does RC know about the terrain elevation in my sim (rather than yours, of the default, or whatever)?

Hi,RC only knows what the Minimum Safe Altitude (MSI) is in a 30 mile radius of an airport but not its direction. RC5 will change that.When flying into or out of an airport surrounded by high terrain you should always select NOTAMS. RC will then give you altitude clearances which you use at your discretion.You should hear "...if able descend flight level one five zero" or words to that effect.Hope that helps.

RC5: that sounds nice. I wonder when.......Thanks for the help.
