Healthy Retreat

There is a measurable difference in the healthiness of the cabin environment and Gulfstream rises above the others.

Cabin comfort is more than simply seat quality, aisle width and headroom.

Natural light that affects mood, increased pressurization that allows your heart and lungs to relax, and cabin air that is 100 percent fresh and completely replenished every two minutes combine to affect the way your body feels after a long flight. And in every respect, no other aircraft, business or commercial, can boast the healthy benefits of cabin technology like Gulfstream.

Consider this: Most of us live and work roughly within about 1,000 feet of sea level. Our bodies can adjust to much higher elevations, but it takes a toll. Flying at a cabin pressure altitude of 8,000 feet, the typical cabin pressurization in other jets, the human body undergoes the physical stress of adjusting to and maintaining that elevation for the duration of a flight. Which is exactly what causes jet lag and why at the end of a long flight on other aircraft, passengers feel exhausted.

That’s why Gulfstream has engineered cabin environments to the lowest cabin altitude available in the industry. So if there are obvious health benefits, why then don’t other business jet makers lower the cabin altitude in their airplanes to match Gulfstream and create a similarly comfortable and healthy cabin? Frankly, because it’s not easy to do.

To control the altitude passengers experience in jet airplanes, high pressure air from the engines is fed into the cabin. The physiological result of having the higher air pressure in the cabin is that your heart and lungs have an easier time oxygenating your blood. Your heart beats more slowly. The oxygen level in your blood remains higher. Your cognitive abilities are greater. And you feel rested, relaxed and engaged upon arrival because your body isn’t fatigued as if you’d climbed an 8,000-foot peak.

To keep the cabin pressure high so the cabin altitude passengers experience is low means the pressure differential inside the cabin versus that of the thin high altitude air outside is significant. To contain that pressure, the fuselage must be very strong, and Gulfstreams are. And those spectacular oval windows that allow so much natural light and vitamin D to flood the cabin demand very careful engineering and advanced materials to contain the higher pressure. It’s an investment that Gulfstream makes in the design of its airplanes to ensure the passenger experience is second to none.

In addition to lower cabin altitudes, Gulfstreams also provide passengers with the freshest air. The entire volume of air inside a Gulfstream cabin is exchanged every two minutes or less. And the superheated bleed air from the engines is filtered and cooled to the precise cabin temperature selected by the occupants. Lesser jets keep air inside the cabin for much longer periods and some recirculate air through the cabin several times. Each circulation allows the air to absorb all sorts of undesirable contaminants and germs.

No other aircraft can boast the healthy benefits of cabin technology like Gulfstream.

The rapid air refresh rate in Gulfstream aircraft means the air simply passes through once and has no time to collect contaminants, bacteria, germs or any other particles. And the air entering the Gulfstream cabin is actually quite pure. The compressors in the engines squeeze the air to many times its natural atmospheric pressure. Squeezing anything, especially air, creates a large amount of heat, hot enough to kill any germ or bacteria that may have been present.

Gulfstream is also a leader in automated cabin pressure control so you never feel a “bump” or “pop” in your ears as the airplane climbs and descends. As the Gulfstream rolls for takeoff, the cabin is very gradually pressurized even before you leave the ground. The pressure control system knows how high you will cruise and the elevation of the destination airport so it adjusts the pressure changes in the cabin very gradually so that most people never realize the cabin altitude is changing.

While Gulfstream cabins offer the latest technology in business productivity and connectivity and boast unrivaled creature comforts, it’s perhaps what is unseen—lowest cabin altitude, most natural light and the purest air—that contributes the most to a healthy, comfortable cabin.

Abundant Natural Light
Sunlight through panoramic windows creates a bright environment for work or relaxation.

Low Cabin Altitude
Keeps heart and lungs from working as hard; subtle pressure adjustments prevent ears from popping.

100 Percent Fresh Air
Rapid refresh rate of 100 percent purified air means no bacteria or contaminants circulate in the cabin.
