B781

B781 is a designation that can refer to several different things, most notably a specific model of Boeing aircraft. The Boeing 787-10 Dreamliner, part of the Boeing 787 family of wide-body, twin-engine jet airliners, is often referred to as the B781. This variant is the longest in the 787 family, offering extended passenger capacity and range compared to its predecessors. It is constructed primarily from composite materials, contributing to its fuel efficiency and reduced environmental impact. The B781 features advanced aerodynamics, a spacious cabin with larger windows, and improved air quality systems for passenger comfort.

Beyond aviation, B781 can also appear as a product code or identifier in various industries. For example, it might be a specific component number in electronics, a chemical compound identifier, or a catalog number for manufactured goods. Without further context, the specific meaning of B781 remains ambiguous, though its association with the Boeing 787-10 aircraft is a common interpretation in the aerospace and general public spheres. The exact nature of B781 is therefore dependent on the context in which it is used.
