The Air InsideThe cabin pressure on the 787 is higher and the humidity higher than other airplanes. Basically, passengers on board will feel like they are at an altitude of 6,000 feet, 2,000 feet lower than a standard flight.
The Dreamliner is a successful aircraft, still in production with more than 1600 delivered or on order. The list price for a new Boeing 787-8 is $239 million dollars. Yet even as international travel opens again for these long-range aircraft, two Dreamliners barely ten years old are waiting for the wrecker's ball.
The 787-8 Dreamliner can fly 242 passengers up to 7,350 nautical miles (13,620 km) in a typical two-class configuration. The 787-9, a stretch of the 787-8, can fly 290 passengers 7,635 nautical miles (14,140 km) in addition to more cargo, allowing airlines the ability to grow routes first opened by the 787-8.
Ecologically, and compared to previous generation wide-body aircraft, the Dreamliner has avoided more than 85 billion pounds of carbon emissions, achieved 20-25% greater fuel efficiency, realized 20-45% more cargo revenue capacity, and produced a 60% smaller airport noise footprint.
The 787's latest problem mirrors production issues discovered over 2020 and 2021 that included improperly fitted shimming that led to paper-thin gaps between surfaces on the Dreamliner's fuselage.
The seats are so cramped in economy that the legroom of a similar seat on a 777 or a 747 feels like a business-class seat. Intelligent engineering allows for seat-backs to recline but to compensate, the seat bottom lunges forward — thereby only providing an illusion of a recline.
For a rough estimate, most jet airliners takeoff and land at , roughly, 140–150 mph. Of course we deal with knots, but for a “civilian”, 150 mph. Has the 787 Dreamliner been a success for Boeing and its customers?
As with every Boeing airplane, the 787 includes many layers of redundancy for continued safe operation, and the electrical system is no exception. For example, Boeing has demonstrated that the 787 can fly for more than 330 minutes on only one engine and one of the six generators and land safely.
•Because the 787 is pressurized at about 6,000 feet rather than 8,000 feet, you'll breathe easier. More oxygen in your lungs means better sleep, less chance of headache, no difficulty breathing (flying at altitude is like sleeping at a ski resort).
