The treaty provides for the open skies regime for the execution of unarmed short-haul flights by States Parties on the territory of other States Parties. The Treaty gives each State Party the right to execute and the obligation to accept observation flights over its territory. The treaty provides for each contracting state a “passive quota”, i.e. the total number of observation flights that each State party must accept over its territory and an “active quota”, i.e. the number of observation flights that a State party can carry out on the territory of any other State party. The “active quota” of a State Party cannot exceed its “passive quota” and a single State Party cannot require more than half of the “passive quota” of another contracting state. Appendix A lists the specific figures for both quotas. The Treaty required States Parties to create groups and redistribute their “active quotas” and to have common “active and passive quotas”. Implementation of the Treaty: The Open Skis Advisory Commission (OSCC), made up of representatives from all contracting states, is responsible for the implementation of the Open Ski Treaty.
The OSCC deals with contract performance issues, decides on contract membership, distributes active quotas and addresses any issues that may arise during the implementation of the treaty. Since 2002, 40 missions have been organised over the UK. There were 24 quota missions carried out by: Russia – 20; Ukraine – three; and Sweden – one. There were 16 training flights from: Benelux (jointly with Estonia); Estonia (in conjunction with the Benelux); Georgia – three (a commune with Sweden); Sweden – three (a commune with Georgia); United States – three; Latvia; Lithuania; Romania; Slovenia; Yugoslavia.  Also since 2002, the United Kingdom has carried out a total of 51 open-air missions – 38 quota missions in the following countries: Ukraine (five); Georgia (seven) and Russia (26); 13 missions were training missions in the following nations: Bulgaria; Yugoslavia; Estonia; Slovenia (three); Sweden (three); United States; Latvia, Lithuania and Benelux. Flights cost approximately $50,000 per mission and approximately $25,000 for training missions with approximately $175,000 per year.  Open ski aircraft may 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 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.
