About the Pilatus PC-24

The Pilatus PC-24 is the world's first business jet designed from the outset to operate from short, unpaved runways, a capability that sets it apart from every other light jet in its class. Introduced in 2018 by Swiss manufacturer Pilatus Aircraft, the PC-24 combines the cabin comfort and speed of a conventional bizjet with the rugged field performance of a turboprop, earning it the marketing moniker "Super Versatile Jet." Its reinforced landing gear, large cargo door, and flat cabin floor make it equally at home on a 2,930-foot gravel strip in the Australian outback or a paved FBO ramp in Manhattan, a flexibility no Cessna Citation or Embraer Phenom can match. Powered by two Williams FJ44-4A turbofans, the PC-24 cruises at 440 knots and climbs directly to FL450, yet lands at just 81 knots with full flaps, slower than many turboprops.

Its 2,000-nautical-mile range and eight-to-eleven-seat cabin have made it a favorite for air ambulance operators, corporate shuttles, and special-mission work in remote regions where runway infrastructure is minimal. The type's modular interior can be reconfigured in under an hour from executive seating to medevac stretchers to cargo pallets, a versatility that has driven strong adoption among hospital authorities and humanitarian operators. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
