The Boeing 787 Dreamliner represents a quantum leap in aircraft design.  It incorporates composite materials instead of predominantly aluminum, and is equipped with revolutionary systems that make it the leader in the long-haul aircraft category.

Features and their resulting advantages to the customer are as follows:

Structural Composites:  The use of these materials result in lightweight, fuel economy and extended range.

Electromechanical Brakes:  Compared to older hydraulic brakes, these are lighter and have increased reliability.

Large size:  The aircraft can carry more fuel, cargo and passengers.

Pressurization:  Because of the composite technology, less pressurization is needed than in conventional aircraft.  The result is that passengers feel less of a sense of jet lag.

Spaciousness:  The cabin design incorporates increased legroom and added amenities such as lounges.

Environmentally “Green”:  The Dreamliner used 20% less fuel per passenger.  This results in fewer carbon emissions and quieter takeoffs and landings.

Structural Superiority:  Compared to aluminum designs, composite technology provides improved structural strength and durability.  The result is longer aircraft life, less maintenance, corrosion resistance and less susceptibility to structural fatigue.

Systems powering:  The Dreamliner has far less reliance on bleed-air powering of onboard systems.  Instead of bleeding hot air from the engines to provide power, the 787 has converted these systems to a largely electric architecture.  This results in improvements in engine start, auxiliary power, de-icing, cabin pressurization and hydraulic pumps.

Computing Systems:  An advanced maintenance control system improves troubleshooting.

Selective Paint Stripping:  The composite body allows chemical stripping of paint from the aircraft skin (no longer requiring hand sanding).

Electrochromic Dimmable Windows:  Providing added passenger comfort.

Interchangeable Engine Types:  The composite wing design facilitates interchange of engine types to the specifications of the customer.

Quick Reparability:  The composite materials allow quick repair in the event of minor damage, allowing quick repairs at the gate.

High-intensity LED Interior Lighting:  Provides improved interior lighting with lower energy consumption.

Reduced Maintenance:  Design permits overall reduction in required scheduled maintenance:  Compared to earlier aircraft, the 787 offers a 30% reduction in airframe and system maintenance requirements (and costs).
