In the realm of private jets, Cessna’s Citation series has long been synonymous with economic efficiency, high performance, and passenger comfort. The Citation I, the forebearer of this successful family, represents the original turbofan-powered business jet that made its mark in the aviation world. Back in 1977, it emerged as a game-changer for its ability to operate from short airfields, maintain modest speeds, all while keeping costs low, with a price range of $790,000 to $960,000. However, in 1985, Cessna eventually phased out the Citation I.

The Citation I underwent transformative changes during its developmental journey, including the addition of thrust reversers, an extended wingspan of 47.1 feet, and increased operating weights. These enhancements aimed to position it competitively among its contemporaries. Powering this small yet agile jet are two Pratt & Whitney Canada JT15D-1/A/B turbofan engines, each delivering a substantial 2,200 pounds of thrust.

Originally equipped with ARC analog radios, the Citation I has since evolved with the times, embracing modern digital avionics technology. Its avionics suite now includes dual Collins VHF comms, VIR 30 navs, ADF 60s, the Sperry APZ 500 autopilot, and Bendix RDR 1100 radar. Despite subsequent model improvements, the Citation I remains a performer, offering a maximum payload capacity of 2,097 pounds and a maximum takeoff weight of 11,850 pounds, soaring to an altitude ceiling of 41,000 feet.

Operating with a two-person crew, the Citation I can carry an extra passenger in the right seat of the flight deck in its single-pilot configuration. Inside its compact cabin, measuring 12.7 feet in length, 4.9 feet in width, and 4.3 feet in height, six passengers can find their seats comfortably. Additionally, it boasts a full-width lavatory and a compact galley or refreshment counter.

In summary, Cessna’s inaugural Citation I brought remarkable performance at an accessible cost, fulfilling a critical need for an entry-level business jet. Between 1971 and 1985, more than 690 of these highly sought-after Citation I and Citation I S/P models took to the skies, leaving an indelible mark on the aviation landscape.
