According to the announcement, in light of the ongoing situation and the possibility of American military action, Iran's air defense systems have been placed on heightened alert. This situation increases the risk of misidentifying civilian aircraft in Tehran's airspace.
It was also reported that the possible presence of a wide range of weapons and air defense systems, along with unexpected responses and the possibility of activating surface-to-air missile systems, will pose a high risk to civilian flights operating at all altitudes and at all flight levels.
EASA notes that, given the high level of tension, Iran is expected to maintain a high level of alert for its air force and air defense systems nationwide. In addition, in the event of American intervention, retaliatory actions against American assets in the region cannot be ruled out, which could lead to additional risks in the airspaces of neighboring countries where US military bases are located.
The safety agency concluded that, together with the European Commission and the member states, it will continue to closely monitor developments to assess whether the risk to European aircraft operators has increased or decreased, in line with ongoing threat and risk assessments.
