To give a little background information regarding this message, it indicates that FlightGear is unable to find an airport name YMML in its main airport data base. The fact that you are getting this message does indicate a few things: Your traffic file is recognized and read in during program initialization. FlightGear needs airport information to get coordinates for departure and arrival, load airport dynamics, etc etc. This information is obtained by referencing the departure and arrival airport ids against those stored in the program's main airport database (located in the file data/Airports/apt.dat.gz). FlightGear's airport database, while extensive, is not complete, and therefore, it is possible that users attempt to create traffic to / from airports that are not listed the database. The program is designed not to crash upon encountering unknown airport information. Instead, FlightGear issues a warning, and and then discards any further processing of the AI aircraft in question. Because YMML is reported as being reported as an unknown airport , you won't be able to see your flight. Now, what's interesting in your case is that YMML is listed in the apt.dat.gz file, so this shouldn't happen. I therefore suspect something might have gone wrong with the formatting of your xml file. Could there be extra whitespaces or other characters that might have influenced this? The fact that you mention 26 spaces between find and "YMML makes me suspicious that this might be the case. I just checked the code, and there doesn't seem to be anything in the program itself adding these spaces, so it would seem to me that they are part of the string that you are trying to match. FWIW, FlightGear version 0.9.10 has indeed this very short and rather unhelpful message, which I/we have subsequently changed to a more helpful: "Traffic manager is unable to find XXXX airport : " where XXXX can be "departure" or "arrival" depending on which airport is the offending one. Please have a look and see if you can spot something obvious surrounding the "YMML" string. If your still not succesful, feel free to send me the file, and I'll have a look.
