The Airbus A380 previously held the title, but the program ended in 2019 due to low demand for the jet. Emirates, which operates 118 A380s, was the only carrier to make a significant investment in the double-decker plane.An Emirates Airbus A380.

Lufthansa is bringing back its beloved A380 jet next year, reversing a pandemic-era decision. Here are the airlines that have resumed flying the plane since 2020.

The 777-9 is also the longest commercial airliner ever built at 251 feet and nine inches, beating out the Boeing 747-8, which is just two and a half feet shorter at 250 ft and two inches.

Insider went onboard the manufacturer’s first-ever 777X test plane, known as Flight Test 1, at the Farnborough International Air Show in England to learn more about the program — take a look.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

The plane is powered by two large GE9X engines made by General Electric. A Boeing 737’s fuselage could fit inside one of the 777X’s engines.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

The engines power the plane’s 13,500-kilometer range (8,388 miles) and offer 10% lower fuel costs compared to the 777-300ER, according to Boeing.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

Inside the jet is a slew of testing equipment and tools, with one of the most important being the large black water tanks located at the front and back of the plane.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

Engineering captain Edwin Navarro told Insider the tanks help control the 777X’s center of gravity (CG), which is necessary for analyzing the stability of the aircraft.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

He explained that engineers shift water between the tanks via pipes to change the plane’s CG. Because some tests need a specific CG, the barrels are important for testing very niche conditions.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

Behind the tanks are several rows of seats arranged as they would be in an economy class. These are for ferrying Boeing staff between test flights.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

The seats give a preview of what a completed 777X interior could look like. The plane is built for ten-abreast seats in economy, which would accommodate up to 426 passengers in a two-class configuration — 30 more than the 777-300ER.Air New Zealand 777-300ER economy cabin with 10-abreast seats.

The configuration competes with the rival Airbus A350. Historically, mainline carriers have only configured the plane with nine seats abreast, minus a few budget airlines like French Bee that have squeezed in ten.Ten seats abreast on French bee’s A350.

However, Airbus is working on a denser cabin configuration that would allow for ten-abreast in economy “without compromising seat width,” company CCO Christian Scherer told FlightGlobal.Nine seats abreast on Italian carrier ITA’s A350.

A lot of the instrumentation, like orange wiring throughout the cabin, is purely used for testing and is not in production aircraft. It sends information to the engineers so they can analyze data in real-time to ensure the plane is performing.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

Herbert told Insider that the average test flight lasts between three to four hours, although they can last as long as eight.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

According to Boeing experimental test pilot James Murrell, the aircraft is one of four 777X planes in the company’s fleet, all of which are based at Boeing Field in Washington state.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

Murrell told Insider that Flight Test 1 has flown about 1,100 hours across more than 400 test flights. As a fleet, the planes have flown a collective 2,500 hours across about 800 test flights.Boeing 777X flying display at the Farnborough International Air Show 2022.

Murrell explained Flight Test 1 is mainly testing the jet’s characteristics, like folding wing tips, which are a brand new technology.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

The folding wing tips on Boeing’s massive new 777X are a first in commercial aviation. Here’s why the plane needs them.

At 235 feet and five inches, the 777X has a 23-foot longer wing span than former 777 models when the wingtips are folded down.Boeing 777X wingspan.

Boeing increased the 777X’s wingspan to generate more lift, which reduces fuel burn by about 10% and makes the plane more efficient than its predecessors.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

However, the longer wingspan would not fit at most airport gates. To eliminate the need for new infrastructure to accommodate the wider jet, Boeing needed a mechanism that folds the wingtips up when parked.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

When retracted, the 777X’s wingspan is the same length as the older 777s, meaning they can fit into airport gates that are already built for current 777 variants.Air New Zealand Boeing 777 at the gate at LAX.

According to Murrell, the wingtips are safe due to the redundancies built into the plane.Boeing 777X.

“We have a whole slew of alerts that make sure the wingtips are extended prior to takeoff,” he said. “It’s part of our before takeoff checklist, which is electronic.”Inside the Boeing 777X cockpit.

Murrell explained that a switch in the cockpit will signal to the checklist that the wingtips are fully extended. “I can’t takeoff without that, he said. “The auto-throttles won’t work, and alarms will sound in the cockpit.”Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

He further explained that the entire system is mechanically locked once airborne, so nothing can be changed during flight. But, as the plane lands and slows to about 50 knots, the wingtips automatically fold.The Boeing 777X at Dubai Airshow 2021.

In the case of a go-around, the wingtips will still be deployed because the plane has to be on the ground and at a certain speed to fold.Boeing 777X.

Murrell also explained that the wingtips are “easy to use and are just a switch in the cockpit,” so the system would be a simple transition for crews switching from flying former 777 models to the 777X.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

However, he said that during test flights, the pilots will note how the crew interacts with the system and if any human factors-related things could be improved.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

As far as the flight deck as a whole, Murrell said the 777X is similar to the 787. The cockpit has all touchscreen displays, which he said are intuitive and effective.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

While Flight Test 1 has its own schedule and specific tests, other aircraft in the fleet have their own purpose. For example, one plane has a nearly complete interior, so that jet is meant for more cabin-related tests.Boeing 777X interior mockup.

Meanwhile, Murrell told Insider that Flight Test 2 just completed a campaign that tested how the plane performed with artificial ice sheets on the wing’s leading edge. “If you have that amount of ice, you want to make sure the plane still flies well, and it does,” he said.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

While the 777X is still in the testing phase, Boeing hopes the plane will have its first delivery by 2025.Boeing 777X Flight Test 1 aircraft at the Farnborough International Air Show 2022.

However, the goal is already well-past Boeing’s original plan, which expected the first jet to be delivered in 2020. Moreover, the planemaker has also stopped production of the jet until at least the end of 2023.Boeing 777X parked at Paine Field in Everett, Washington.

While Boeing is temporarily halting production, with London-based analyst firm Agency Partners calling the announcement a “dreadful set of results,” Emirates CEO Tim Clark told Simple Flying that he is still committed to the 777X.Emirates Boeing 777X rendering.

“As far as the 787s are concerned, we’re having a good hard look to see whether they fit into the program or not,” he said. “It’s far more important to us that they (Boeing) concentrate on getting their 777X out the door.”Emirates Boeing 777-9, Boeing 777-8, and Boeing 787 rendering.
