Gulfstream Avions d'affaires

Gulfstream slapped down a new gauntlet on Monday with the introduction of the 7,500-nm range G650ER, claimed by the firm to be the world’s longest-range business jet. Just as impressively, Savannah’s new über-jet will be able to fly 6,400 nm at Mach 0.90.

“This opens up significant nonstop city pairs, including New York to Hong Kong, Dallas to Dubai and San Francisco to Delhi,” says Scott Neal, senior VP for worldwide sales and marketing. “G650ER owners in Dubai will be able to reach most of the contiguous United States. From Hong Kong, operators can connect with the Eastern Seaboard of the United States.”

Flight tests are well under way. Earlier in 2014, a G650ER set a new National Aeronautic Association record [pending] by flying the 7,494 nm from Hong Kong to Teterboro, New Jersey, in 14 hours 7 minutes, cruising at Mach 0.865 and landing with fuel in excess of NBAA IFR reserves. That means it should be able to dash between New York and Tokyo at Mach 0.90.

G650ER virtually is identical to the G650 that entered service in 2012, except for a 4,000-lb. increase in fuel capacity, max ramp weight and MTOW. BOW remains unchanged, thereby preserving the aircraft’s 1,400-lb. full fuel payload, assuming typical equipment. Sea-level / standard day takeoff field length for G650ER is increased to 6,299 ft. from 5,858 ft. for G650.

Fuel capacity of the wet wings is increased by a modification to the fuel system. That will be accomplished by means of an upcoming service bulletin due for release in 1Q15. The SB also will be available as a $2 million retrofit for existing G650 aircraft. List price for new G650ER aircraft is $66.5 million in 2014 dollars.

The added heft won’t have a significant impact on climb performance. Initial cruise altitude is FL410, unchanged from that of the base model. Current G650 operators say they routinely cruise at Mach 0.87 to 0.88 while burning an average of 3,100 lb. per hour [pph]. Fuel consumption at Mach 0.90 averages about 3,500 pph.

Only on the longest missions do they poke along at Mach 0.85, averaging 2,800 pph. Qualcomm’s chief pilot Candace Covington said she’s flown a G650 from Shanghai to Carlsbad, California, in 13 hours 33 minutes at Mach 0.85 and “landed with lots of reserves.” The extra hour-plus of range should enable G650ER operators to fly nonstop from Carlsbad to Shanghai.

Paul a écrit:Le 5X aura bientôt un nouveau compétiteur de taille, le GVII (ou G700 ou G750) connu jusqu'à maintenant sous le nom de code P42. À court terme, il remplacera le G450 mais selon moi une version allongée remplacera plus tard le G550. Le développement est également assez avancée, peut-être au même niveau que le 5X (en cours d'assemblage) à ce qu'on m'a dit. Peut-être un lancement plus tard cette année.

Parait que le PW800 serait à bord (mais c'est un peut-être)

But new to the G500 and G600—and a first for civil aviation—are the active-inceptor sidestick controls supplied by BAE Systems. These are electrically back-driven, so they appear to be mechanically linked side to side: When one sidestick is moved, the other moves with it. The sidesticks also move in response to autopilot inputs, providing the pilots with tactile and visual feedback.
