Canadian Gulfstreams - Part 6

During the past 60 years, three key specifications have driven the evolution of corporate jet design. They are: range, speed and cabin size. A new standard was set with the first flight of the Gulfstream G650 on November 25, 2009. It can fly 7,000NM at Mach .85 - a 17% improvement on the G550's maximum range of 6,000NM at M.85. Perhaps more importantly, the G650 can travel 6,000NM at M.90. Gulfstream has since introduced an enhanced fuel capacity modification that is available for G650s either in service or on order. The G650ER can fly 7,500NM at M.85 or 6,400NM at M.90.

Not to be left behind, Bombardier has responded with its new Global 7500. While it and the G650ER share the same published long-range cruise speed of M.85, high-speed cruise speed of M.90 and top speed of M.925, the Global 7500 has an advertised maximum range of 7,700NM versus the G650ER's 7,500NM. The most significant difference between the two aircraft appears to be cabin size. Assuming the installation of a dedicated crew rest station aft of the cockpit, the G650ER has a three zone cabin, while the Global 7500's longer fuselage accommodates a four zone cabin.

Given that more than 400 G650s/G650ERs have been ordered to date, it will be interesting to see how large the market ultimately is for corporate jets that cost more than US$65 million.

Of the more than 340 Gulfstream G650s/G650ERs currently operating, so far only two wear Canadian registrations. The first example, a G650 (6162, C-GNDN), was delivered new to a family in Calgary in December 2015. Having previously had a G450 and a G550, this upgrade might have been expected. The second unit is a G650ER (6252, C-FYRC). It had previously served as a Gulfstream Aerospace demonstrator before being purchased by a Calgary investor in November 2017.
