The airspace in western Austria has been monitored more closely by the Federal Army since Monday. The background to this is that the World Economic Forum, which is attended by around 50 heads of state and government and around 2.700 delegates, is taking place in Switzerland. Traditionally, the Swiss Confederation and Austria work together in security areas during this event. Under the operation name "Dädalus", the Federal Army is monitoring the airspace in western Austria more closely. For example, additional aircraft, helicopters and mobile radar systems are being deployed in the federal states of Tyrol and Vorarlberg. Additional air patrolling is also being carried out. According to the responsible commander, this is intended to ensure security in Austria and Switzerland. The WEF, which is taking place in Davos, lasts until January 21, 2023. For this reason, a restricted flight zone has also been imposed over the federal state of Tyrol. According to official information, the Federal Army is deploying around 1.000 soldiers, nine helicopters, 20 aircraft and eleven planes. The aircraft will be used primarily from Innsbruck and Landeck. Four Pilatus PC-7s and three PC-6s will be used from the first-mentioned airport. Four Bell OH-58 helicopters will be kept on standby from Landeck. Eurofighters will be used from Zeltweg if necessary. Austria and Switzerland signed a new agreement some time ago that includes extensive cooperation in the area of ​​airspace security against non-military threats. This came into force on February 1, 2019. They had already worked closely together during the annual WEF. Suspicious aircraft may be tracked across borders, but the use of weapons in the other's territory is prohibited without prior approval.
