The Czech Republic is born on the 1st of January 1993, from the partition of the Federative Republic of Czechoslovakia into two different states : the Czech Republic, which kept the former flag and roundel, and the Slovakia, which chose new symbols.
Roundel, three sectors, blue white red, blue border.
The czech roundel is identical to the former czechoslovakian roundel. It is painted of the read part of the fuselage of the helicopters, and of the tail of the planes. The blue sector is always facing forward. On the sides, the white part is upside ; on and under the wings, the white is facing outwards, the roundels appearing in a symmetrical way.
