Does RC4 take terrain height into account when giving vectors and altitude assignments? Last night it told me to descend and so I did, then it vectored me right into a mountain lol. I was in VMC so I was able to avoid it but had I been in the soup, it would have been lights out for the Columbia 400. I am using FSGenesis 38m Mesh so the mountains are likely a bit taller/shaped differently (more realistically) than the default fs9 mountains. Would this have any effect on the situation?Secondly - does RC4 take into account actual MOCA and MEA (minimum obstacle clearance altitude & minimum enroute altitude) when on airways? The documentation says that RC4 takes into account MSA and MVA - but my experience last night with the mountain suggests otherwise - unless it is limited to the terrain elevation that came with the default FS2004 and it doesn't take into account the higher terrain afforded by the add-on mesh, which is perfectly understandable. Just trying to understand better how RC4 works.

as one of the tutorials illustrates, when flying into mountainous areas, choose the arrival notams options. then all descent clearances will be preceeded by "when able"also the msa of the airport, on the controllers screen, controls the altitude at which you will be descended too.you can adjust the msa, if it doesn't meet what is published on the chartsjd

thanks - i actually just went reading and was looking through the tutorials. i had kindof taught myself how to use RC4 but obviously there are some things that i didn't learn by just trial and error so I guess I ought to RTFM and check out the tutorials too :D
