John, I as I understood we don't have any real artificial/ interacting ATC in FGFS. That means the messages are more or less just for fun. If we use a generic rwy no we could argument that it is the wrong rwy for the given wind. The better solution would be to program a working/ interacting

I have some basic questions about the --metar command-line option. AFAICT the getstart.pdf manual doesn't mention this option. The --verbose --help message mentions the option, and implies that it takes an argument ... but doesn't say anything about the syntax or semantics of the argument. I
