INCREASED COMFORT AND PRODUCTIVITY
Jetliner passenger cabins are typically pressurized to the equivalent of
8,000 feet of elevation during cruise. This is well within the comfort range
for most passengers. Studies show that increasing cabin air
pressure (reducing the effective elevation) helps passengers
stay more alert during long flights—and arrive feeling more
energetic. Boeing Airplane Services offers a fully integrated
kit to reduce BBJ cabin altitude to 6,500 feet, which will
enable you to maximize your productivity—in the air and at your destination.
