The CitationJet, and its 525-series successors, remain one of the most popular light jets in operation today. Known for their efficiency, reliability, performance, and ease of operation, these aircraft have earned a lasting place among owner-pilots. With low direct operating costs, simple systems, and single-pilot capability, the CJ series has become the go-to platform for those seeking jet performance without unnecessary complexity.

The story begins in the 1960s when the only real option in the light business jet space was the Learjet. While it was sleek and fast, it was also loud, fuel-hungry, short on range, and expensive to operate. It lacked practicality, especially for conservative business owners in the Midwest looking for something more sensible. Cessna responded by conceptualizing the Fanjet 500, designed as a quieter, slower, and more affordable alternative with better runway performance. In 1971, the aircraft was certified as the Citation 500, named after the famed Triple Crown winning racehorse, and positioned as a true business tool. It was practical, straightforward, and easy to fly. In 1977, Cessna further solidified the type’s reputation with the introduction of the Citation 501, which achieved FAA Part 23 certification for single-pilot operation (I/SP) offering another major advantage over the Learjet.

As the Citation line matured, the aircraft grew in both capability and complexity, but also in cost. Over time, the market began to demand a return to simplicity—something smaller, more efficient, and cost-effective, while still jet-powered. Cessna, under the leadership of Russ Meyer, approached the challenge by starting with the engines. The new aircraft would need a lighter, more efficient engine with a superior thrust-to-weight ratio, especially since the new design would carry less fuel than previous models. Williams International, a relatively small engine manufacturer known for cruise missile propulsion systems, had just the solution: the FJ44. With that engine selected, Cessna turned to the airframe.

A major design requirement was aerodynamic efficiency. The new jet would feature a laminar flow wing, engineered to reduce drag and improve fuel economy. This wing, when paired with the Williams FJ44, established the fundamental platform for the new model. The result was the CitationJet, Model 525, certified in 1992. Though certified under FAA Part 23, it was designed to meet many of the more stringent Part 25 safety standards typically required for larger jets. This was the first Citation designed from the ground up specifically for the single pilot, optimized for simplicity, performance, and safety.

Russ Meyer also recognized a key market opportunity. At the time, most owner-pilots transitioned from single-engine pistons to multi-engine pistons—usually a Cessna 340, Beechcraft Baron, or Piper Navajo. At the top of that pyramid was the King Air. Once pilots reached that stage, there were few practical steps beyond. The CitationJet changed that. It offered a clear progression from turboprop to jet, with a platform that could outperform the King Air 90 in many key areas. The CJ was faster, flew higher, burned less fuel per nautical mile, and, most importantly, was easier to fly. Many argue it was even more reliable than the King Air, which was already well known for its reliability. The CitationJet proved to be a major success and delivered exactly what it promised.

As avionics and cockpit technology advanced, so did the CitationJet. The next evolution came in the form of the CJ1, which brought notable upgrades including a redesigned interior and new avionics. The biggest leap was the switch from the Honeywell EFIS system to the Collins Pro Line 21. The two large-format 8″x10″ displays dramatically improved pilot situational awareness and reliability while simplifying cockpit workload. Along with the Pro Line 21, The CJ1 introduced features such as upgraded FMS, V-speed menus, AHRS, upgraded weather radar integration, TCAS, and engine performance data.

The CJ1 would evolve further into the CJ1+, which again brought a new leap in cabin comfort, but the “+” designation was primarily driven by new engine technology and the introduction of the FADEC-equipped FJ44-1AP engines. FADEC allowed for precise digital engine control, optimizing performance and reducing workload even further. The CJ1+ could climb to 41,000 in just 32 minutes, almost half the time of the CJ1 and once established in cruise, could fly up to 20 knots faster. With FADEC, the mechanical thrust attenuators from the CJ1 were no longer necessary and were removed in the CJ1+. In addition to the engine improvements, the CJ1+ featured a fully integrated three-screen Pro Line 21 cockpit, creating a cohesive, avionics suite reminiscent of larger jets and airliners. These enhancements brought the CJ1+ to the top of its category, offering a level of performance, efficiency, and simplicity that was unmatched in the light jet segment.

The 2008–2009 recession marked the demise of the CJ1+ program, with only 102 units delivered. But the CE-525 story was far from over. In 2013, Cessna reintroduced the platform as the Citation M2. It featured a completely redesigned interior, a new Garmin G3000 touchscreen flight deck, and FJ44-1AP-21 engines. The M2 redefined the 525 once again, with cutting edge cockpit technology and another boost in performance and speeds over 400 knots. With the M2 Gen2 currently in production and the Gen3 on the horizon, the CJ story continues, stronger than ever.

Even today, the CitationJet series remains one of the most popular and widely flown light jets in the world. The Citation has earned a devoted following by consistently delivering what owner-pilots value most: simplicity, performance, reliability, and efficiency—all within a platform that continues to evolve with the times.
