Boeing Co. sees the future, and it doesn\u2019t include jumbo passenger jets. Not its own iconic 747. Not the Airbus SE A380. The US planemaker has dropped the category reserved for four-engine behemoths from its annual forecast for the commercial-aircraft market. Instead, Boeing predicts that airlines will use more efficient twin-engine jets for long-range flights - like its 787 Dreamliner and 777X, or a mid-market plane that\u2019s on the drawing board. By leaving so-called very large aircraft off its two-decade projection for a $6.05 trillion jetliner market, Boeing said it was reflecting a market reality: There is little to no chance of reviving sales of those models. The Chicago-based company and Airbus already had pared production of their biggest aircraft as orders dwindled, and Boeing has warned it may stop making the 747\u2019s passenger version. \u201cWe don\u2019t see much demand for really big aircraft going forward,\u2019\u2019 Randy Tinseth, Boeing\u2019s vice president for marketing, said at a briefing ahead of the Paris Air Show, which began Monday. \u201cWe find it hard to believe that Airbus will deliver the rest of their A380s in backlog.\u2019\u2019 Airbus still sees a long-term market for the planes although it didn\u2019t log a single A380 sale last year. The Toulouse, France-based manufacturer says airlines will need larger jets as passenger traffic doubles and congestion limits the number of flights into megahubs, particularly in Asia and the Middle East. The European company projects potential industrywide sales of 1,400 of the largest commercial aircraft, valued at $454 billion through 2037. That compares with Boeing\u2019s 20-year forecast for 80 deliveries that Tinseth outlined Tuesday at a Paris show presentation. \u2018Lighter Gauge\u2019 As the jumbo era ends at Boeing, the planemaker sees a new market emerging for mid-range airplanes overlapping the largest single-aisle and smallest twin-aisle jets. That differs from the stance at Airbus, which announced plans at the Paris show to make enhancements to the A380 in the hopes of one day reviving orders. \u201cThey went big and heavy, we went small and efficient,\u201d said Mike Delaney, Boeing vice president and general manager for airplane development. \u201cWe\u2019ll overfly our competitors, put a lighter gauge on things.\u201d Airbus is refining the double-decker A380\u2019s design, including adding 4.7-meter (15-foot) winglets, to boost fuel efficiency by as much as 4 percent. Tinseth dismissed the strategy. \u201cPutting winglets on an airplane that\u2019s too big doesn\u2019t make that airplane any smaller,\u201d he said. The mid-range model Boeing is developing would seat between 220 and 270 travelers and fly about 5,000 nautical miles. The goal is to spur growth with jetliners that avoid hubs and link smaller cities on routes that aren\u2019t properly matched to today\u2019s aircraft. Think Washington to Prague, Japan to India, or within China\u2019s \u201cGolden Triangle\u2019\u2019 of Shanghai, Guangzhou and Beijing. Watch this also: \u00a0Airlines also could use the new jet - dubbed the 797 or NMA, for new mid-market airplane - on transcontinental flights to replace aging Boeing 757 and 767 jets. Budget carriers could graduate from single-aisle jets to the larger planes for more-popular routes. Tinseth projects a potential market of 4,000 to 5,000 sales in that segment over 20 years. Clogged Aisles Airbus has already made advances in that market with its largest single-aisle plane, the A321neo, and is exploring a stretched version that would carry more than 240 passengers. While that narrow-body would probably be cheaper than the new Boeing dual-aisle, the U.S. company sees a competitive advantage in a design that lets people board and disembark far more quickly. Single-aisle aircraft like the Airbus A320 and Boeing 737 will still rule the market, accounting for nearly three-quarters of total sales, according to Boeing\u2019s forecast. The planemaker predicts a need for 29,530 narrow-bodies valued at $3.18 trillion through 2036. The next most popular type will be small wide-body aircraft, like the Boeing 787 Dreamliner and Airbus A330, accounting for 5,050 deliveries or 12 percent of forecast sales, Boeing predicts. Sales of very large aircraft will probably be confined to Boeing\u2019s niche-market 747-8 freighter and a handful of jets for VIPs, like the next Air Force One for the U.S. president. The hump-backed 747 - which in 1970 ushered in a new era of mass long-range travel - eventually will be replaced at the top of the jetliner food chain by Boeing\u2019s 777X. The first delivery for that 400-seat plane is scheduled for 2020. \u201cThe biggest airplane in the market moving forward is going to be the 777X,\u201d Tinseth said.
