If an incident should escalate for some reason, the pilot has the right of self defence, according to international regulations. In order to reduce the risk of making mistakes, causing a subsequent escalation of the situation, there are national as well as international regulations to adhere to.
The national IKFN regulations deal with intervention, violations, peace and neutrality and provide a framework for handling violations of Swedish territory and air space in peacetime and in relation to neutrality.
Since the pilot is expected to be able to communicate with signs, radio messages, light signals, warning fire and by tipping the aircraft, there is also an international standard for this, the essence of which should be known to all pilots, civilian as well as military. This standard is regulated by the international standards organisation for aviation, ICAO.
The fighter aircraft are given various degrees of alert, depending on the developments in the vicinity of Sweden and on the assessed level of threat. The highest state of alert means that pilots are ready to take off as soon as they are ordered to do so.
