Contexto
States may want to develop an emergency preparedness plan that prescribes actions to be taken by appropriate national authorities in the interest of national security to control air traffic under emergency conditions. A plan for emergency security control of air traffic would define the authorities, responsibilities, and procedures to identify and control air traffic within a specified area during air defence or national emergency conditions.
