I was reading one of the news headlines about the certification of the Embraer Lineage 1000, and the article stated "The cabin, with three temperature zones, has a maximum altitude rating of 7,000 ft." I believe that 7,000 ft is a typo, so can anyone verify this and tell me what the actual max altitude is? Thanks.

The maximum CABIN altitude is 7,000ft. This is different than maximum AIRCRAFT altitude. Cabin altitude pertains to the pressure inside the cabin itself.

The 787, which is said to have considerable improvements in cabin pressure and humidity, has a 6000' cabin pressure. Not much different than the Embraer biz-jet.

In the business jet arena, more extreme offerings are in the making. The new G650, for instance, offers a maximum cabin altitude of 4850ft while cruising at 51,000ft altitude.
The industry standard for commercial aircraft (up to now) is 8000ft. Those 2000ft less cabin altitude should be very noticeable on the 787. If they can maintain higher levels of cabin humidity as well (due to reduced structural corrosion concerns), the comfort level should be very significantly improved.
BTW, the A318 Elite roll-out rate is somewhat sparse, with the above example only the fourth from the announced number of orders to date. Did the others defer or cancel?
