The problem is the air temperature, which should be 15 degrees C above sea level, but the aircraft can be at different altitudes that METAR does not know about. So, in METAR I give 15 degrees C, which is basically untrue and irrelevant, because in the flightgear branch I recalculate the temperature so that above sea level it is always 15, and I recalculate this local one taking into account the altitude of the aircraft.

Planning to merge this stuff later today, any changes or feedback I should know before going ahead with that?
