*SUA (Special Use Airpsace) geographical coordinates are derived from valid AIP of Czech Republic.*
*Coordinates are rounded to nearest angle second.*
*Maximum positional error caused by coordinates rounding taking into account radius of big Earth circle (according to FAI sphere R=6371km, where one angle degree is 111,195km of this big circle, one angle minute is 1853,25m (1NM) and one angle second is 30,885m) and maintaining rounding rules is 16m.*
