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.

Sounds reasonable, I’ll take a look in detail when back form vacation if no one beats me to it.

Kind regards,
