A lower cabin altitude modification is now available for Boeing Business Jet (BBJ) operators. The new feature will offer 6,500-foot cabin altitude instead of the standard 8,000-foot cabin, providing passengers with an improved level of comfort.

The lower cabin altitude feature, available in early 2003 from Boeing Commercial Aviation Airplanes Technical Services and Modifications, will be sold as a kit that can be installed after delivery

of a green aeroplane or as a retrofit on in-service BBJs.

“It’s all about passenger comfort,” said Lee Monson, president of Boeing Business Jets. “A 6,500-foot cabin means less cabin pressure change on climb and descent, as well as more oxygen in the cabin during cruise.”

The kit can be installed by certified maintenance personnel, completion centres or Boeing. The company says no structural changes will be necessary and no increase in maintenance will be required until the aircraft surpasses 30,000 flights.
