Operational Context
Boeing 787-9 Dreamliner — long-range widebody twinjet
The 787-9 first flew in 2013 and entered service in 2014. It shares the composite fuselage and wing technology of the 787-8 while offering increased seating and range. The aircraft features modern avionics and improved cabin systems.
Powered by two Rolls-Royce Trent 1000 or General Electric GEnx turbofan engines producing approximately 64,000 to 74,000 pounds of thrust (285 to 329 kN) each, the 787-9 cruises at around 485 knots (900 km/h). Maximum takeoff weight exceeds 560,000 pounds (254,000 kg). Seating typically ranges from 250 to 290 passengers.
The 787-9 has become one of the most widely adopted Dreamliner variants. Its combination of range and capacity supports long-haul routes with improved operating economics. The aircraft remains central to many airline fleets.
