Outdoor aircraft can have video cameras, panoramic optics and frames for natural light photography, infrared line scanners for day-night capability and synthetic glare radars for a day/night at any weather function. The quality of the photographic image allows the recognition of essential military equipment (for example.B. allows a Member State to distinguish between a tank and a truck), which allows considerable transparency of the armed forces and activities. Sensor categories can be added and capabilities improved by an agreement between Member States. All sensors used in open skis must be marketed for all signatories.  The resolution of the image is limited to 30 centimetres.  [Quote required] It is difficult to say how many countries today use the open skies policy in civil aviation, because countries sometimes use it unilaterally or by mutual agreement between partner states. And sometimes, after a while, they stop using it. The initial agreement was signed on April 30, 2007 in Washington, D.C. The agreement entered into force on March 30, 2008. The second phase was signed in June 2010 and has been applied on an interim basis until all signatories are ratified.  Whether the government of a country pursues the open skies, protectionism or a mixture of both depends on factors such as the economic and political interests of the government. America`s open skies policy goes hand in hand with the globalization of airlines.
With airlines` unlimited access to our partners` markets and the right to fly all intermediate points and crossing points, open-air agreements offer maximum flexibility for airline alliances. This agreement allows any airline in the European Union and any airline in the United States to fly anywhere between the two countries. In November 2018, the UK reached an individual “Open Sky” agreement with the US, which will succeed the EU agreement after Brexit.  Such agreements are often referred to as bilateral (with two countries) or multilateral (with three or more countries). Another term, which includes the same concepts as “open skies,” is the term “open airspace.” The term “open skies” dates back to the late 1970s, when the United States began to follow air agreements with other countries. Until 1982, it had signed 23 such agreements with smaller nations, and in 1992 an important step was taken when, despite the objections of the European Union, the Netherlands signed the first “open skies” agreement with the United States. Some states apply this policy only at certain airports, not the country as a whole. For example, Russia has an open skies policy at the airports of Sochi, Kaliningrad and Vladivostok.
Israel is successfully pursuing this policy at its main Ben Gurion airport in Tel Aviv. Among other Central Asian countries, Kyrgyzstan is the most advanced country in this regard.
