It should go without saying that private jet passengers generally enjoy more space, more comfortable seats and more advanced cabin systems than their airline counterparts. But the benefits of all these luxuries can be badly undermined by inadequate humidity levels in the cabin that can make the VIP traveler as weary as an economy-class pauper at the end of a long flight.
For parched Dubai 2009 visitors here in the desert it is hard to imagine that excessive humidity could be an issue. But no matter what the local outside environment, it can soon become a problem inside an aircraft full of people, not only in terms of passenger and crew comfort, but also in terms of the amount of fuel burned in carrying the excess payload of water generated by condensation.
With ever larger numbers of ultra-long-range business jets taking to the skies, individual complaints about dry air in the cabin have grown to a chorus of demands for humidifiers. But while manufacturers would like to oblige, most have yet to come up with a system that is both airplane and people friendly.
Associated Air Center has ordered a CTT Systems Zonal Comfort System for a Boeing 767, for which the Dallas-based facility is installing a VIP interior. Associated is the first U.S. completion center to install the system. According to CTT, a Swedish manufacturer based in Nykoping, the system addresses problems associated with dry air by raising humidity levels in the cabin to 25 percent.
