The Citation CJ2 + is a small business jet that replaces the previous CJ2 model. The design of this aircraft is similar to all CitationJet models. A number of innovations have been introduced: it has an automatic engine control system FADEС, a flight and navigation system Collins Pro Line 21. The latter includes two adaptive flight displays, a liquid crystal display of primary flight PFDs and a multifunctional display MFD. The Collins 3000 and Pro Line 21 CNS flight control systems were also implemented.
