Boeing 777X Test Aircraft: A Glimpse into the $442 Million Jet

Though it’s been a long and challenging journey, Boeing is now developing the largest two-engine airplane in the world.

 A flight test engineer revealed to Insider at the airshow that Flight Test 1 has flown for more than 1,300 hours over roughly 540 trips.

Each aircraft has a distinct function, concentrating on a variety of things like auto-landing, environmental testing, low-speed performance, and extended dual-engine range operations.

The testbeds are crucial for certification and aid Boeing in proving to authorities the dependability and safety of the technology and engines used in its airplanes.

 The twin-engine airliner will be longer than any previous 777 variant, with a wingspan of 235 feet and 5 inches.

Compared to previous and rival aircraft, the wings are 10% more efficient and help to generate more lift.

According to the FAA, each aircraft type has unique airport requirements that range from the size of the gate to the width of the taxiways. The space disparity between an Air New Zealand Boeing 777 and a Lufthansa Airbus A340 is depicted in the image above.

In order to save airports and operators time and money, Boeing made sure the 777X wouldn’t need any additional infrastructure.

More lift is produced via wingspan lengthening, which enhances performance and lowers running costs.

Wing Design, Foldable Wingtips, and Testing Insights

Though it’s been a long and challenging journey, Boeing is now developing the largest two-engine airplane in the world.

The total wingspan, which is approximately 212 feet when the wingtips are retracted, is similar to older 777 models.

At the Farnborough Airshow in July 2022, Boeing experimental test pilot James Hanley informed Insider that the wingtips will fold once the aircraft slows to roughly 50 knots.

He continued by saying that a go-around wouldn’t present a problem because the folding mechanism can’t work until the aircraft reaches the ground.

The aircraft is designed to warn the pilots if the wingtips are not extended before takeoff, for example, by sounding an alarm or failing to engage the auto-throttle.

The wingtips are also checked off the pilots’ pre-flight checklist, which adds another level of security.

It can also access information like how well it performs when flying in bad weather or how well it recovers from an uncontrollable dive or spin. Workers can move water back and forth between the tanks in the front and rear of the aircraft to test the jet under various centers of gravity.

Engineers and pilots collaborate to organize and brief the missions’ testing, evaluations, and objectives.

Pilots will also provide the engineers with information about how the systems operate and whether there are any issues related to human factors, or how humans interact with the machine.

 While the 777X and A350 are competitors, the 777-9 model offers improvements like larger windows and increased capacity.

The 777-9 can accommodate up to 426 passengers in a two-class layout with 10 seats across in economy. In order to more effectively compete with the 777X, Airbus actually modified the A350’s design to support 10 abreast rows.
