Embraer Praetor 500 et 600

The Praetor 600 steps up the capabilities of the Legacy 500 with new winglets, additional fuel capacity, and more powerful Honeywell HTF7500E engines.

The winglets of the Praetor 500/600 are canted out farther and are larger than those on the Legacy 450/500, adding 25 inches of length to both the left and right wing (50 inches increase in wingspan) and 22 inches in wingtip height.

The Praetor 500 boosts the fuel capacity of the Legacy 450 from 12,108 pounds to 13,058 pounds, by expanding the fuel volume to match that of the Legacy 500. Both the Legacy 450 and 500 share the same wing design, so this wasn’t a huge change.

The key performance improvement for the Praetor 500 is greater coast-to-coast range at 3,250 nm (long-range cruise, four passengers, two crew, NBAA IFR reserves), up from 2,900 nm. Takeoff distance is longer, however, at 4,263 feet. Maximum payload is 2,921 pounds, and payload with maximum fuel 1,600 pounds.

The Praetor 600 does even better, thanks to the more powerful engines and a fuel capacity increase, which amounts to 2,928 pounds split between two tanks on the belly of the fuselage; a forward tank and what Embraer labels its "ventral" tank farther aft. Added to the 13,058 pounds in the wing, fuel capacity of the Praetor 600 is 15,986 pounds.

The Praetor 600’s engines required no physical changes, just a software update to the Fadec, which now allows the HTF7500E to produce 7,528 pounds of thrust, flat-rated to ISA +18 deg C, up from 7,036 pounds in the Legacy 500.

With the added fuel capacity, the Praetor 600 can fly 3,900 nm with four passengers, two crew, and NBAA IFR reserves. Maximum payload is now 4,001 pounds and payload with maximum fuel 2,533 pounds.
