Here is a view flying into Las Vegas airport. As you can see the airport is raised on some platform. Anyone know what causes this and how I can fix it? Is the field elevation incorrect in the AFCAD file? Or is it the FSGenesis mesh which is setting the elevation of this spot?http://forums.avsim.net/user_files/130036.jpg

I think it has to do with elevation and how the simulator cannot simulate a sloping runway so the result is this platau. This cannot be fixed until a new fs renders elevation with airports better. I also see that you are definatly missing some textures there as well. As far as I know KLAS has satalite rendered textures and it is one of the more highly detailed airports in fs. It looks like the ground textures have become generic for some reason.

It's the mesh. A very unfortunate side effect of it. :(

As a native of the great city of Las Vegas, and a former McCarran Intlemployee, I assure you that the airport is level with the surrounding area. Anyway, I once had the same issue, I guess the way that I got rid of this was by installing the Las Vegas scenery from fsfreewareIt used to be payware, but is now free, It's pretty realistic, but the imagery they used to make it is quite outdated, and the night lighting isn't that great.Jeff

As above, it's the mesh. You have to flatten airports in MSFS so if there is any elevation change in the surrounding area, you will get the plateau effect.

Not dispute anyone's local knowledge but the FAA says the Las Vegas airport is not flat.That is the approach end of Rwy 19L & 19R.According to the current FAA airport diagram for KLAS - the end of those runways is at elevation:19L - 2078 ft - 19R - 2089 ft - a difference of 11 feet between the two runways. The official airport elevation is 2181 feet - which is also the FS default altitude for the airport.That is 103 feet higher than the terrain off the airport polygon north of the Rwy 19L threshold.The default FS terrain mesh, as we all know, is not very detailed. It takes several hundred feet to resolve the 100+ foot elevation discrepancy between East Bell Drive and Tropicana Ave - probably the terrain out to Harmon Ave or farther is at the wrong elevation with the default mesh.When you install a detailed mesh with tighter resolution - then the 100+ foot difference is resolved in a very short distance. You can see portions of what should be Tropicana Ave are on the very steep sections of the slope.Unfortunately - this is one of those have to live with it issues - though you could drop down to the mesh design forum and work with them to create a small area mesh around the airport to resolve the differences.

Like you say, the chart shows a gradient on 1R of 1.1 degree down,and 1.2 down for 7R. IRL when you taxi out you can see that pretty clearly (It looks like going up a hill on T/O).scott s..

My 'KSEA' is the same landing at 34R?Dave T. .........On the lovely warm Devon Riviera and active 'FlightSim User's Group' member at http://www.flightsimgrpuk.free-online.co.uk/
