Pro Line Fusion Upgrade For CJ2+ Approved By FAA With a recent Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) in hand the Collins Pro Line Fusion flight deck is now available for installation on the Cessna Citation CJ2+. This is nothing new per se for the CJ3 as Collins received their STC for the same flight deck for the CJ3 back in 2017. It is only now being filtered down to older Citation models. Regardless it is a great upgrade from the factory-installed Pro Line 21 flight deck on the CJ2+. Three large 14.1 inch landscape oriented touchscreen displays are part of the Pro Line Fusion upgrade in the CJ2+ and naturally facilitate a host of advantages and capabilities that were not possible on the Pro Line 21. Synthetic Vision System (SVS) is now available which is an added bonus to pilots situational awareness.
