Under the Payload Range Increase Program, (Stans, Switzerland) announces that it has developed a version of its PC-24 jet that offers more range and a higher payload while retaining the aircraft’s aerodynamic characteristics and flight handling, in addition to a range of new interior options for customers.

According to the company, the PC-24 contains weight-optimized ground-spoilers and main landing gear doors, as well as new composite ducts and fairings in the rear fuselage. It delivers a payload increase of 272 kilograms (600 pounds). Its maximum range with six passengers on board has also been increased by 370 kilometers to 3,704 kilometers (2,000 nautical miles). With full fuel and single-pilot operation, the maximum payload is 596 kilograms (1,315 pounds). On shorter routes, the jet provides a maximum payload of 1,406 kilograms (3,100 pounds).

Pilatus engineers carried out an extensive campaign of flight tests to expand the entire envelope for the higher design weights. At sea level and maximum takeoff weight, the takeoff distance required is just 941 meters (3,090 feet). “We did what the project name says — ‘Payload Range Increase Program,’ or ‘PRIP’ for short — and focused on increasing the payload capacity and range,” Tobias Waeber, project leader, explains. “At the same time, we wanted to retain the PC-24’s aerodynamic characteristics and flight handling, so that meant no major changes to the external shape. Instead, we concentrated on weight, aiming to increase maximum takeoff weight while also reducing the empty weight. Improvements to the wing and fuselage structure seemed to be the most effective way of increasing the PC-24’s payload and range.” Waeber notes that it will now be possible to transport more luggage and passengers on shorter routes, and on longer routes the crew may be able to avoid a refueling stop.

Nevertheless, like every major project, the PC-24 upgrade was confronted with challenges. “We had to rethink and admit to ourselves that a few modifications simply wouldn’t be enough to achieve our goals,” Waeber says. “We struggled to shave off every gram wherever we could. It was only at the end, when we were able to verify the sum of over 700 modifications to the structure alone, that we realized we had actually exceeded our initial targets.”

Performance became a notable upgrade. As Waeber explains, “on short routes, the PC-24 significantly exceeds the maximum payload of its closest competitors by over 15%, and maximum range with four passengers is slightly better as well. Astonishingly, the PC-24 achieves this with a significantly larger cabin and smaller fuel tanks. And we remain the only aircraft in this class able to operate at so many airfields.”

Besides technical improvements, the interior has been redesigned as well. The noise level in the cabin has been reduced through various optimizations,, such as the ventilation system and engine intake. The cabin interior and welcome center now offer greater flexibility, ergonomics and freedom of movement. There is also additional storage space and a large work surface.  The PC-24 also includes a new inflight entertainment system and a large side-facing divan seating arrangement option.

All PC-24s from serial number 501 onward will also feature a new function enabling the provision of predictive maintenance services. Immediately after landing, aircraft data will be forwarded to Pilatus for analysis and, if required, a predictive maintenance recommendation can be made to the operator.
