Today in Aviation: Boeing’s 777X Completes Maiden Flight. MIAMI – Today in Aviation, Boeing successfully staged the first flight of its 777X, the world’s largest twin-engined commercial aircraft, last year. At 252 ft (77 m) in length, the 777X is the longest commercial jet. Additionally, the airplane’s wingspan, boosted by the world’s largest folding wingtips, will measure 235 ft (72 m), almost the same as the airplane’s length. 24, 2020, © Leeham Co.: In a year filled with bad news, Boeing finally had something good to crow about. The 777-9’s first flight is today. Plus 4 uno. It comes about a year late, due to design issues with the GE Aviation GE9X engine that powers the airplane. Boeing 777-9X First Flight – January 25, 2020. The world’s longest and largest twin-engine airliner, the Boeing 777-9X, has finally taken to the skies for its maiden flight, offering a ray of hope for the troubled US aviation company following months of grim headlines. After days of abysmal weather, airplane WH-001 took from Paine Field, home of Boeing’s wide-body factory, north of Seattle, on Saturday morning.
Widebody passenger transport jets made their introduction in the 1960s early 70s in the form of the Boeing 747, McDonnell Douglas DC-10 and the Lockheed L1011 Tristar. Preparing for the retirement of the Boeing 727 faithful workhorse, Boeing in 1978 announced the 757 narrow body, as well as the 767 wide-body which was to go up against the Airbus A330. Boeing also was kicking around a Boeing 777 jet idea which was a tri-jet, to go up against the DC-10 and L1011.
ETOPS
The Boeing 757 and 767 models were well accepted by the market. The timing was fortuitous, as in the early 1980s new regulations were introduced governing the operations of twin-engine aircraft on transoceanic routes. ETOPS, (Extended-range Twin-engine Operational Performance Standards), allowed certificated aircraft to fly up to three hours (ETOPS180) from the nearest available alternative airfield. The Boeing 767 began to be used under this regulation on oceanic routes that did not require the seating capacity of the larger widebodies.
Filling the Gap
There was still a gap in Boeing’s stable of aircraft between the Boeing 767 and the Boeing 747 which needed to be filled.
McDonnell Douglas announced the MD11 to replace the ageing DC10. Airbus had the Airbus A330 and A340. In 1986 Boeing floated ideas to create an enlarged Boeing 767. Called the Boeing 767-X, the design had a longer fuselage, larger wings with winglets and a wider cabin. The response from airlines was not encouraging at all. The market called for an even wider fuselage, flexible cabin layouts and better fuel economy than could be delivered by any Boeing 767 variant.
A New Design
In 1988 Boeing reacting to the market, acknowledged that a brand new design was called for and the Boeing 777 idea was born.
In a departure from the norm, Boeing gathered 8 leading airlines to become part of the design group. The Working Together Group, as it was called, was made up of All Nippon Airways, American Airlines, British Airways, Cathay Pacific Airways, Delta Air Lines, Japan Airlines, QANTAS, and United Airlines. Rather than presenting the market with what Boeing perceived as their idea of what was required, customers had direct input. Resorts sportsbook online.

January 1993 | Boeing designers and around 240 airline teams gathered at Everett to address around 1,500 design issues. Modifications were made. Cathay Pacific influenced an increase of the fuselage diameter, All Nippon Airways demanded lengthening of the base model fuselage, whilst British Airways asked for more interior flexibility and increased weight options. |
4 January 1994 | Assembly begins on the first aircraft. |

15 May 1995 | United Airlines takes delivery of its first Boeing 777. |
30 May 1995 | The 777 with Pratt and Whitney engines becomes the aircraft to be awarded ETOPS-180 on entry into service. This means the Boeing 777 can be used for trans-oceanic services provided it does not fly further than 180 minutes from an available alternative landing site. |
7 October 1996 | The Boeing 777 200ER with extended range and increased payload capability made its maiden flight. |
17 January 1997 | The Boeing 777 200ER received both FAA and JAA certification. |

2 April 1997 | A Malaysia Airlines Boeing 777 200ER flying from Everett to Kuala Lumpur broke the record for an aircraft non stop flight. It flew 20,044Km (10,823NM) in 21 hours and 23 minutes. It was aptly named Super Ranger. |
16 October 1997 | The Boeing 777 300 made its maiden flight. At 73.0 Metres (242.4 Feet) it was the longest airliner to have flown, a record to be held until the Airbus A340-600 was introduced. |
4 May 1998 | The Boeing 777 300 received type certification from both the FAA and JAA. |
27 May 1998 | Cathay Pacific, the launch customer for the Boeing 777 300, received their first aircraft. |
29 February 2000 | Boeing launched its next-generation twin-engine program concentrating on creating longer-range variants of existing types. Named Boeing 777-X it was a slow starter due to the downturn in the airline business in the early part of that decade. The first design to be offered, the Boeing 777 300ER was ordered by Air France. Ten were ordered. |
24 February 2003 | Boeing Boeing 777 300ER made its maiden flight. |

Story on takeoff updated following completion of flight
The Boeing 777-9 completed its first test flight Saturday, landing at Boeing Field in Seattle at 2:01 pm local time after a three-hour, 52-minute mission over Washington state. Powered by a pair of General Electric GE9X turbofans, the big twin took off northbound at 10:09 am from Boeing’s Paine Field complex in Everett, Washington, marking the start of a flight test program now expected to lead to certification in 2021.
The first flight came after a weather-related postponement on Thursday and an aborted mission on Friday, when gusting tailwinds prevented a northbound takeoff planned as part of the test flight itinerary. Winds on Saturday blew at less than 10 knots, well below the limit at which program managers might have needed to call off the flight for the third time.
The first of four dedicated 777-9 flight test airplanes, WH001 will now undergo checks before resuming testing. The test fleet, which began ground trials in Everett last year, will endure a comprehensive series of tests and conditions on the ground and in the air over the coming months to demonstrate the safety and reliability of the design.
Boeing had originally hoped to gain FAA certification for the larger of a duo of planned 777X variants this year, but engine-related delays and promises of more intense scrutiny from regulators arising from the twin crashes and grounding of the 737 Max have created expectations of a longer wait.
The largest turbofan engine ever developed for an airliner, the GE9X remained a so-called “pacing item” as the industry gathered for the Dubai Airshow in November, by which time the company had delivered three fully compliant engines following retrofit of redesigned stator vane assemblies in the engines’ compressors. By the time of first flight, GE Aviation had delivered six test engines out of eight built to support the Boeing flight test program. In all, the company has built 20 GE9Xs.

Speaking with AIN just ahead of the show, GE9X program head Ted Ingling explained that the process that led to the fix to the problem titanium part involved revamping its geometry to ensure a proper wear profile.

“This particular one came at us a little late in the program,” said Ingling at the time. “And the nature of it required us to go inside the engine to fix it. And that, by definition, given when we found it and where we found it, drove the schedule. I will say it’s unfortunate from a schedule standpoint but fortunate from a product standpoint. I much preferred to find this in a place where we could fix it and robustly get it behind us than to have something show up in flight tests or certainly in the field.”

In a written statement, a GE spokesman told AIN that the company expected engine certification “later this year.”
