Why is the 787 Dreamliner so good?

The 787 was the first major commercial aircraft to use carbon fiber composite components in the fuselage and wing construction. These make the aircraft lighter but still offer high strength. New, more efficient engines. The 787 is designed to take either the General Electric GEnx or the Rolls-Royce Trent 1000 engine.

In addition, the 787 is much quieter than other aircraft, so pilots can enjoy a quieter cockpit. The 787 also offers improved cabin comfort for airline pilots. The Dreamliner's cabin is pressurized to a higher altitude than conventional aircraft, which makes it easier to breathe and reduces fatigue during long flights.

The Dreamliner's lightweight composite structure contributes to reduced noise levels, both inside and outside the aircraft. The use of advanced soundproofing materials and quieter engines keeps the cabin environment more tranquil for passengers.

The carbon-fibre structure of the 787 allows the aircraft to be pressurized to a much higher level than on many other aircraft types. The lower the cabin altitude, the better you feel both during and after the flight, allowing your body to adjust to your new time zone more quickly.

This is quite probably the reason for the popularity of the mid-sized Boeing 787-9 Dreamliner, which offers its operators a very useful balance of both range and capacity. This mirrors the Boeing 737 MAX family, whereby the MAX 8 model (which is the second-largest of four variants) is by far the most popular version.

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.
