Many of the usual suppliers for Dassault aircraft have been selected for the 5X, although Héroux-Devtek will be the landing gear supplier (Messier Dowty provides the 7X gear). The nosegear will have a “dual-chamber, for comfort.”

Hamilton Sundstrand, a United Technologies company, is providing the electrically started APU (“easy start, all the time”), with Thales AES supplying the new starter-generator system.

“We worked a lot on the acoustic treatment to ensure the 5X is a good neighbor on the ground, too,” said Olivier Villa, Dassault senior v-p for civil aircraft. United Technologies will also supply the ram-air turbine, with the emergency ram-air scoop being on the nose of the aircraft (unlike other Falcons).

UTC Aerospace Systems is supplying the air data system; its architecture is a development of the 7X’s system: four smart probes, associated with angle-of-attack sensors and “compliant with new requirements for icing systems.”

Eaton is supplying the hydraulics system (with noncorrosive Mil-H-83282 red-oil hydraulic fluid). The electrical system will be a 115-VAC network, which is “new to the Falcons,” said Villa. With the fuel system, he said, “We have ensured that fueling will be very fast and very accurate.”

French company Zodiac Intertechnique is supplying the fuel and oxygen systems. Zodiac will also supply the flight-deck oxygen system, and the crew masks have a new “saver function,” said Villa.
