2. Boeing 777x First Flight Date

After two failed attempts, called off due to high winds, the latest addition to the 26-year-old Boeing 777 family has finally taken to the air. At 09:08 am, Saturday 25 January 2020, aircraft registration WH-001 started its takeoff run on runway 34 Left at Paine Field, Everett. With an 8 knot tailwind, broken clouds at 3,000 feet with 6 miles visibility, the largest twin-engine jet took a mere 30 seconds to become airborne. Applause and cheering from the crowd was drowned out by the worlds biggest jet engines, the GE Aviation GE9x.

Maiden flights of new airliners don’t happen very often, maybe once or twice a decade. Whilst the first flight of the Boeing 777x is a cause for excitement, Boeing must be feeling the pressure of getting this completely right in light of the 737 MAX situation. But enough of that.

The test flight lasted four hours out over the Pacific Northwest, a major milestone and the beginning of a very rigorous aircraft certification program. Before the aircraft can be delivered to airlines and begin carrying passengers, it has to go through a certification process. This is done with the F.A.A. (Federal Aviation Administration) and then no doubt with other agencies such as E.A.S.A. (European Union Aviation Safety Agency) before it can fly to, or overfly those regions. By current estimates, Boeing expects to be in a position to start delivering the first aircraft to customers in 2021. The first of those is expected to be Emirates. The order book for the 777x stands at 309 airframes with a list price of US $442M per aircraft. Of course, this is not necessarily what airlines will pay as they will have negotiated with Boeing for discounts around things like, number of aircraft ordered, or being the launch airline. Nevertheless, the sooner Boeing starts delivering, the sooner the income for this project will start.

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. 11 hours ago  MIAMI – Today in Aviation, the Boeing 747-8F made its first flight, successfully completing its high-speed and taxiing tests, in 2010. With the intention of designing and manufacturing a worthy replacement for the Boeing 747-400 in all its variants, the company had already begun to accumulate a series of ideas at the end of the 90s for the new line of the.

So after 26 years of 777s (Tripple Sevens), what is so special about the 777x? Well, the original 777 was a step forward in its day, being computer designed it brought a lot of new ideas to the airliner design table. The 777x is carrying on that tradition by using technologies that have been tried and tested in the Boeing 787 Dreamliner. This includes using more composite materials in its construction, to make use of lighter stronger materials as well as materials which are far less susceptible to corrosion. Larger windows and an updated passenger cabin will be great news for passengers on this aircraft that Boeing maintains is the most efficient twin-engined airliner in the world.

The standout feature is the folding wingtip………

The stand out feature, however, is the folding wingtip. This feature, until now, was typical of fighter aircraft that were assigned to aircraft carriers. To save space when the aircraft was stored below decks, its wings would be folded upwards and thereby reducing the side to side space required for its storage. This is a concept that Boeing went with. To create the largest twin jet in the world, that is required to fly further than the previous version, was going to require a wing that gave more lift than the previous version. Winglets could have solved the problem to some extent, but it has been found that a longer tapered wing gives more optimal lift. The Boeing 787 and the Boeing 747 8 are testament to Boeing’s findings in this area.

So why folding wingtips? Well, let’s look at the Airbus A380. When it was introduced in the early 2000s, airports were required to make adjustments to gate areas to enable a much wider aircraft to be accommodated. They had to be “A380 Ready” before that airliner could land there. A huge upheaval and expense but it was seen as the new future and therefore was seen as an investment in that future. We now know of course that the days of the A380 are numbered, now that the giant twin airliners are coming of age. Boeing wanted to avoid the restrictiveness of requiring airports to upgrade to be able to handle an oversized wingspan. They wanted the 777x to be able to fly everywhere that the current generation of 777s can fly to. So was born the folding wingtip idea. The wingtips allow the 777x to change from a wingspan of 235 feet in the air down to 213 feet on the ground.

As the wingtips are a totally new technology in the passenger airliner space, the F.A.A. has come up with a set of 10 conditions that have to be satisfied before certification can take place. Boeing has stated that the non-deployment of the wingtips on takeoff can lead to catastrophic results. This is logical, as a fully laden aircraft, depends on the lift that those wingtips provide. If you suddenly have smaller wings than required, you are going by road with tragic results. The 10 conditions are designed to put fail-safes in place to

prevent the non-deployment of wingtips on takeoff as well as the failure of the wingtips to stay in place during flight. These conditions revolve around a comprehensive warning system to alert the crew to the fact they are attempting takeoff without the wingtips deployed. In addition, if that is ignored, there is the ability for the aircraft to prevent takeoff until wingtips are deployed. With every new technology comes a whole raft of things to consider and conditions to be tested for.

Like the Boeing 787 Dreamliner which started its early days as the 7E7, the 777x will no doubt be dropped in favour of the actual variant names of 777-8 and 777-9. Some basic statics on the two models are as follows:

At 251 feet, the Boeing 777-9 will be the longest commercial aircraft in the world.

The road to this first test flight has not been a smooth one. From the time that the 777x was first rolled out of the hangar in March 2019, it was found that the new GE9x engine experienced excessive wear when run. In September when the wing stress testing was done, there was an explosive decompression event when a tear appeared in the fuselage. The manufacturing of the 777x was to be done in a fully automated assembly line by robots. Challenges in this area have forced Boeing to revert back to the traditional human-driven process.

The 777x is in the air at last. We certainly look forward to watching its progress toward certification.

Four hours after its historic 10:09 a.m. departure from Everett, Washington, Boeing’s newest and longest twin-aisle airplane, the 777X, successfully completed its first flight when it landed to the cheers of a crowd at Boeing Field in Seattle.

“The 777X flew beautifully, and today’s testing was very productive,” said Capt. Van Chaney, 777/777X chief pilot for Test & Evaluation. “Thank you to all the teams who made today possible. I can’t wait to go fly your airplane again.”

Chaney and Chief Pilot Craig Bomben flew the airplane from Paine Field in Everett, over Washington state. During the flight, they worked through a detailed test plan to exercise the airplane’s systems and structures while the test team in Seattle monitored the data in real time. The airplane, WH001, will now undergo checks before resuming testing in the coming days. It is the first of four dedicated 777-9 test airplanes.

Employees who witnessed either the takeoff from Paine Field in Everett, Washington, or the Boeing Field landing shared why they turned out on a chilly, overcast weekend to be a part of it.

“It’s cold, yes, but it’s very heartwarming to see our product that we have worked on so hard just take flight,” Diego Castano, 777/777X account manager for Customer Engineering said during the morning takeoff. “We can produce incredible machines, beautiful machines that actually bring the world together.”

Brent Snickers was determined to see it when he arrived with his camera at Boeing Field for the landing. The 12-year Fabrication employee in Auburn, Washington, works on a team that supplies paint packages to the 777X program. He had waited with thousands of others in the rain Friday to see the takeoff before it was postponed due to strong winds.

“This morning (Saturday) I watched the takeoff on TV, then I got in my truck and hurried up here to watch the landing. It’s a step forward, for the positive, for The Boeing Company,” Snickers said.

Boeing 777x First Flight Date

Saturday’s flight is the latest milestone in an effort to build the 777X that involves Boeing sites and partnerships in the U.S. and around the world.

“Our Boeing team has taken the most successful twin-aisle jet of all time and made it even more efficient, more capable and more comfortable for all,” said Stan Deal, president and CEO of Commercial Airplanes. “Today’s safe first flight of the 777X is a tribute to the years of hard work and dedication from our teammates, our suppliers and our community partners in Washington state and across the globe.”

The 777X is based on the 777, the most successful twin-aisle airplane ever, and integrates advanced technologies from the 787 Dreamliner. Through advanced aerodynamics, the latest generation carbon-fiber composite wing and the advanced GE Aviation GE9X engine, it is designed to be the largest and most fuel-efficient twin-engine jet in the world.

To build it, Boeing invested more than $1 billion to construct the Composite Wing Center in Everett to manufacture the largest commercial airplane wing the company has ever built for the 777X.

The 777X, which launched in 2013, includes 777-8 and 777-9 variants. To date, the 777X has outsold the competition by nearly 2 to 1 with orders and commitments for 340 airplanes.

The first 777X rolled out of the factory in March 2019. First delivery is slated for 2021.

Ed Gillette, 777X Customer Engineering senior manager, called seeing the first flight “a privilege,” and reflected upon the often personal significance for him and other employees.

“I’ve been at Boeing over 20 years, my family has worked for Boeing for more than 40 years. And there are few things as an engineer that give me more pride than seeing a flying machine that makes the world a better place,” he said.
