All airplane producers no doubt are continuing to assess the near term and long term business indications of last week’s National Business Aviation Association’s convention and exhibition, which was a huge success for attendees and exhibitors alike.
Gulfstream should be particularly happy. It received very strong customer interest in its newest large-cabin, long-range jets: the G500/G600, both of which are clean-sheet designs. The company has letters of intent from an unspecified number of prospective buyers. The next step will be converting these letters to firm contracts spelling out terms and conditions.

The new aircraft not only have larger cabins than the G450 and G550, but they will also fly higher, faster, quieter and farther—on less fuel. High-speed cruise for both aircraft is Mach 0.9. At Mach 0.85 long-range cruise speed, the $54.5-million G600 has a range of 6,200 nm, compared with the G550’s 6,000 nm. The 43.5-million G500 has 5,000-nm range, compared with the G450’s 4,220 nm at Mach 0.8. In addition to a larger fuselage cross-section, the new jets share with the G650 fly-by-wire controls and systems and wing aerodynamics.
