Aviation Technical English for aircraft maintenance engineers (Авиационный технический английский язык для студентов-авитехников)

60 BOEINGAIRCRAFTS Design The fuselage is of fail-safe aluminium design. The wings are of fail-safe design with aluminium alloy-structure with a corrosion-resistant skin. The nosecone, wing and fuselage fairings, fin tips, the fairings of the flap actuators and other non-stressed components are constructed from glass or carbon fibre reinforced plastics (GFRP and CFRP). The rear parts of the engine nacelles are constructed of graphite, Kevlar and glass fibre composites. In February 2000 an advanced carbon graphite winglet developed by Boeing became available as an option on the 737-800. The 8ft blended winglet provides additional performance benefits in terms of extended range, up to 6,000lb more payload and a saving on fuel. The first 737-800 aircraft with winglets flew in May 2001 in service with the German Carrier Hapag-Lloyd Flug. Flight deck In July 2005, Boeing launched the 737-900ER which can carry up to 215 passengers. The flight deck accommodates the pilot and co-pilot. A head up display can be fitted as an option. The flight deck is equipped with a Common Display System (CDS) from Honeywell Air Transport Systems incorporating six flat panel liquid crystal displays. The CDS software can be programmed to allow the presentation of data in a format replicating that of previous 737 electronic flight systems or that of the Boeing 747-400 and Boeing 777 primary flight and navigation displays. The aircraft can be fitted with an optional global positioning system, satellite communications and a dual flight management system. Cabin The cabins are typically arranged in a two-class configuration with first-class passengers four abreast and tourist-class passengers six abreast.
