"The-new Boeing ""Dreamliner"" aircraft has which numerical designation?"
Boeing 787 Dreamliner Boeing 787 Dreamliner The Boeing 787 Dreamliner is an American long-haul, mid-size wide-body, twin-engine jet airliner made by Boeing Commercial Airplanes. Its variants seat 242 to 335 passengers in typical three-class seating configurations. It is the first airliner with an airframe constructed primarily of composite materials. The 787 was designed to be 20% more fuel-efficient than the Boeing 767, which it was intended to replace. The 787 Dreamliner's distinguishing features include mostly electrical flight systems, raked wingtips, and noise-reducing chevrons on its engine nacelles. The aircraft's initial designation was the 7E7, prior to its renaming in January 2005. The first
RLM aircraft designation system was introduced in order to provide a simple and unambiguous identification of every German civilian and military aircraft, be it fixed-wing or rotary-winged, and its corresponding airframe design. The heart of the new system was a (theoretically) unique number assigned by the RLM. In internal paperwork, this number was simply prefixed "8-" (or, in the case of sailplanes, subject to a separate numerical list, "108-"), while "9-" indicated aircraft engines, with 109 prefixing reaction engines (gas turbines, pulse-jets and rockets). The new standardized type designation added two letters representing the manufacturer; Dornier ("Do") and Rohrbach ("Ro") already used this practice.
