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.
No one likes to endure the sticky feeling of excess humidity, but lack of humidity in aircraft cabins at altitude can be a major cause of discomfort and travel fatigue.
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.
Comments are due today on an FAA draft letter of interpretation released April 3 on the meaning of the term “known icing conditions.” At press time, 82 comments had been filed, mainly by individuals.
A new NASA study claims that man-made cirrus clouds formed by commercial jet engine exhaust might be responsible for increased surface temperatures detected in the U.S. between 1975 and 1994.
Climate data shows that cirrus cloud cover over the U.S. has increased by 1 percent per decade, and the report says the rise is likely due to commercial air traffic.
