Update: To observe this bug, I don't even need to taxi. I can just sit at the starting point of runway 31L at JFK with the engine off. After sitting about 8 minutes, I observe nan messages on the console. One interesting thing is that *no* floating point exception was raised this time. The F

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

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 A

Overheard at KSFO in FG: >>> Golf Foxtrot Sierra Cleared to land This is not realistic. It would be quite unusual for SFO Tower to give a landing clearance without specifying which runway. Suggestion: Cessna Golf Foxtrot Sierra, runway one zero right, cleared to land ^^
