About the Cessna Citation CJ4


With the designation Cessna 525C the CJ4 is a stretched and enhanced derivative of the CJ3 and ultimately a descendant of the original CitationJet. The aircraft was announced at NBAA in October 2006 with first prototype flight taking place on May 2008 and the first production CJ4 flew on May 2009. FAA certification was awarded in March 2010 and first delivery the following month. The aircraft made an EBACE debut in May 2010 and received EASA certification in May 2011.

Up To Date Technology

The largest of today’s extended CitationJet derivatives is also the most up to date with equipment and technology. Earlier in 2013 Cessna requalified its lithium-ion batteries underlining the jet maker’s confidence in these sources.

Cessna remains the only business aviation or general aviation manufacturer that has publicly committed to switching to these batteries as a power source on aircraft and after the reintroduction on the CJ4 the batteries are being added to the larger Citation aircraft such as the new X and the Sovereign. There are plenty of advantages for operators selecting the CJ4. It is approved for single-pilot operations and shares a common pilot type rating with the other CJs (a pilot rated to fly any one of the CJs is rated to fly them all).


The CJ4 has a range of 2,002 nautical miles (3,710 kilometers) and a top speed of 453 knots (839 kilometers an hour). The aircraft has a takeoff roll of 3,310 feet (954 meters) at maximum takeoff weight. The CJ4 is powered by two Williams International FJ44-4A full authority digital engine control engines and features a four-screen Collins Pro Line 21 avionics suite.

It has a takeoff roll of 954 meters (3, 130 feet) at maximum takeoff weight and it capable of a direct climb to 13,716 meters (45,000 feet) in just 28 minutes.


The flight deck features the Rockwell Collins Pro Line 21 avionics, MultiScanTM Hazard Detection System, and the company’s award winning Venue High Definition Cabin Management System is also on the aircraft. The fully integrated Pro Line 21 avionics have been taken to new levels of user-friendliness and intuitive understanding. The package features four huge 8 x 10-inch AMLCD color displays teamed with dual Control Display Units (CDUs) forward of the throttle quadrant. And while pilot workload has been reduced, the cockpit is highly conducive to the work that is required.
