Gulfstream Aerospace is lowering the cabin altitude of its G700 flagship to 2,916 feet at 41,000 feet, marking an improvement from the originally announced 3,290-foot cabin altitude. The change, Gulfstream said, will give the 7,500-nm airplane the lowest cabin altitude of any large-cabin business jet.

“This new, industry-leading cabin altitude is a result of our ongoing investments in customer health and safety and will provide even more comfort for passengers over the ultra-long-range flights the G700 is capable of achieving," said Gulfstream president Mark Burns.

Along with the low cabin altitude, Gulfstream has designed the cabin to have 100 percent fresh air, “whisper-quiet” noise levels, a high-definition circadian lighting system, 20 panoramic oval windows, and a seating design with advanced ergonomics.

Eyeing a 2022 entry-into-service timeline, Gulfstream flew the first fully outfitted production test aircraft on April 15. Plans call to examine more than 15,500 test points on the aircraft cabin, which can accommodate up to five living areas, to ensure its comfort, maturity, and durability.

The fully outfitted aircraft joined the five flight-test vehicles already in the G700 program that had collectively accrued some 1,100 hours by mid-February, about a year after the initial G700 took to the skies for the first time on Feb. 14, 2020.
