Although the Standard Cirrus was a follow-on to the original Cirrus design, it is a completely different aircraft with a 15 meter wing with airbrakes on the top surface only, an all flying T-tail and a steel tube skeleton in the wing fuselage center section.  The Standard Cirrus won the first U.S. Standard Class Nationals in 1969, was 1 and 2 in the 1972 Nationals, and compiled an impressive record as a collector of world andnational distance and speed marks.  It is one of the most popular ships with U.S. private owners and continues to place well in both regional and national competition.  In 1975 an improved version called the Standard 75 introduced redesigned wing fairings, larger airbrakes and other improvements.  No longer in production in Germany, the Standard Cirrus, Cirrus 75, and Cirrus 81 versions have been introduced in large numbers in Yugoslavia under license from Schempp-Hirth ATC.
