Cessna has secured US certification for its Citation X+, which – with a verified maximum speed of Mach 0.935 – has simultaneously secured the mantle of the fastest civil aircraft in service.

The Gulfstream G650 comes in close second, with a maximum speed of M0.925.

The Citation X+ was launched in 2010 as an upgraded version of the then 14-year old Citation X. The latest model is powered by a pair of FADEC Rolls-Royce AE3007C2 turbofans – the latest version of the AE3007C that powers the Citation X.

The type also features a Garmin G5000 flightdeck, an increase in maximum payload to 1,140kg (2,500lb), a boost in maximum cruise speed to 530kt (982km/h) from 460kt, and an increase in range to 3,410nm (6,320km). The X+ also features a longer cabin and winglets, as standard.

Deliveries of the $22 million midsize business jet are under way.
