※ 引述《cppwu (肩膀痠痛 ..)》之銘言： : Source: : http://boeing.mediaroom.com/2015-03-18-Boeing-747-8-Intercontinental- : Receives-FAA-Approval-for-330-Minute-ETOPS : http://goo.gl/zAOAIu : 簡單結論: 這是非雙發機第一次取得 ETOPS 認證。 : EVERETT, Wash., March 18, 2015 /PRNewswire/ -- Boeing (NYSE:BA) has : received 330-minute Extended Operations (ETOPS) approval from the : U.S. Federal Aviation Administration (FAA) for the Boeing 747-8 : Intercontinental. It is the first time a four-engine airplane : has received this type of design approval. : With this approval, required for four-engine passenger airplanes : built after Feb. 2015 to fly beyond 180 minutes from an en-route : alternate airport, the 747-8's design is approved to conduct : 330-minute ETOPS missions. These missions allow operators to fly : long-distances more directly on virtually any worldwide city pair routing. : Although ETOPS has been a requirement for twin-engine airplanes : since the 1980s, the regulations have recently been applied to the design : of passenger airplanes with more than two engines. : "Our customers will benefit from this additional level of reliability : inherent to ETOPS design approvals while still leveraging the vast : network of routes ideal to the 747-8 capabilities, including 330-minute : ETOPS routes," said Bruce Dickinson, vice president and general manager, : 747 program, Boeing Commercial Airplanes. "The 747-8 already offers : fuel savings from an improved aerodynamic design. Flying long-distance : routes directly helps our customers fly even more efficiently – : saving fuel and emitting less carbon dioxide." : With 83 airplanes in service with 11 customers, 747-8s have logged : more than 619,000 flight hours and more than 101,000 flight cycles. 剛跟朋友討論到這個東西他問真的是單引擎飛5.5小時嗎於是就稍微翻了一下資料發現下面這一段FAA關於ETOPS的內容 All passenger-carrying airplanes with more than two engines and more than 180 minutes flying time from an adequate airport (at a one-engine-inoperative cruise speed under standard conditions in still air). 如果我理解沒錯的話這應該是超過三個引擎的客機在單引擎失效的狀況下要飛超過180分鐘吧應該不是單引擎飛5.5小時.... -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 114.43.155.97 ※ 文章網址: https://www.ptt.cc/bbs/Aviation/M.1426767005.A.871.html

你確定原文中他用330分鐘通過這個認證不是遵循單引擎失效的標準？標題就寫取得FAA ETOPS認證了… 747這種大架的單引擎飛5.5小時也太猛了點 ※ 編輯: sandpail (114.43.155.97), 03/19/2015 20:21:36 ※ 編輯: sandpail (114.43.155.97), 03/19/2015 20:22:30
