The first flight of the Cessna Citation CJ4 jet was conducted in the spring of 2008, demonstrating in practice that the expectations of its manufacturers were fully satisfied. Following the publication of the Citation CJ4 model's first test results, a noticeable stir rose in the aviation world, which came with no surprise: the Cessna Citation CJ4 exceeded in all key APC parameters - speed, range, takeoff and landing characteristics. Also, this small jet turned out to be lighter and more powerful than expected. Cessna Citation CJ4 wings were designed from scratch, using new aviation computer technology. The result was a reduced copy the 680: the Citation Sovereign, with only a small difference is its contour edge.
