If Austro Control's plans go ahead, there will no longer be any on-site weather service at Salzburg and Innsbruck airports in the future. Both federal states are up in arms against this, as critics see significant disadvantages in the planned centralization in Vienna. It has long been known that Austro Control's flight weather service at Innsbruck Airport is to be closed down. In the future, the data relevant to pilots is to be supplied from Vienna. It has now been announced that the office in Salzburg is also on the brink and is also to be centralized in Vienna. A trial operation is currently underway in which the provision of weather data is collected both in the traditional way by on-site staff and by the ACG headquarters in Vienna. This has been the case since April 2022. In the future, the meteorological data for Salzburg and Innsbruck airports will only be provided from Vienna. There is increasing criticism of this, as there are fears that centralization could be at the expense of flight safety. However, Austro Control has strongly denied this. However, there are internal reports that contradict the official view of the ACG. These are actually only intended for "internal use", but the Austrian Broadcasting Corporation reports on the content. For example, the head of the Salzburg air traffic control office is of the opinion that the reliability of the new system that is to replace the office is "not reliable". For example, the sensors would provide data that he would classify as questionable. In particular, they would not be able to detect slight fog, which often occurs in isolated areas in Salzburg.
