Delta Air Lines just ordered 100 Boeing 737 MAX 10 aircraft — the largest of the MAX family.
The cabin will be split into first class and economy and fly from major hubs like Seattle and New York.

Delta Air Lines has placed a $13.5 billion order for 100 of Boeing's 737 MAX 10 jet — the largest of the MAX variant. The deal also has an option for 30 more planes.

The MAX 10 is one of two planes in the MAX family that does not yet have regulatory approval to fly. The other model still undergoing certification is the company's smallest variant — the 737 MAX 7.

Boeing is on a tight deadline to get the MAX 10 certified. If it does not receive regulatory approval by December 31, 2022, then federal law will require the manufacturer to upgrade the cockpit to meet the latest safety standards.

Boeing is on a tight deadline to get the MAX 10 certified. If it does not receive regulatory approval by December 31, 2022, then federal law will require the manufacturer to upgrade the cockpit to meet the latest safety standards.

The current cockpit design, which is similar to earlier 737 variants, is favored by airlines because it doesn't require additional pilot training, Delta SVP Mahendra Nair said on Monday, per the Wall Street Journal.

The current cockpit design, which is similar to earlier 737 variants, is favored by airlines because it doesn't require additional pilot training, Delta SVP Mahendra Nair said on Monday, per the Wall Street Journal.

However, if Boeing misses the December 31 deadline, the MAX 10's crew alert systems would differ from the MAX 8 and 9, requiring airlines to pay for separate training.

Nair explained that if Boeing has to upgrade the systems, the airline "will have to rethink about where we are." But, Delta said the deal has "adequate protection" where the carrier can choose to purchase a different MAX variant, the Business Journals reported.

A Boeing spokesperson told Insider at the Farnborough International Airshow that the certification timing is "completely in the hands of the regulator," but said, "Boeing's plan is to certify the plane — that's the intention — and we're still working on that path."

If Boeing can't get the plane certified by the end of the year, the planemaker may ask for an extension from the Federal Aviation Administration, which the agency can grant, according to Senator Maria Cantwell (D-Wash).

However, Boeing CEO Dave Calhoun told Aviation Week in early July that if the plane is not given a waiver, then the planemaker may cancel the program, saying "a world without the MAX 10 is not that threatening." However, he added he does not expect to shelve the plane, but "it's just a risk."

The order comes as Boeing trails European aircraft manufacturing giant Airbus, which recently won a $37 billion order from China's three biggest airlines. A Boeing spokesperson said they missed out on the deal due to "geopolitical differences."

Boeing is still recovering from the crash of two Boeing MAX planes in 2018 and 2019 that led to a worldwide grounding of the jet, causing the planemaker to fall behind Airbus.

However, Delta's order, as well as United Airlines' order for 200 MAXs last year, suggests airlines are putting their trust back in Boeing.

Walking inside, the first thing I noticed were giant black tanks. According to a Boeing flight test engineer on the plane, they are water barrels that are used to control the center of gravity during test flights.

Walking inside, the first thing I noticed were giant black tanks. According to a Boeing flight test engineer on the plane, they are water barrels that are used to control the center of gravity during test flights.

He explained that there are also tanks in the back of the plane, and engineers will load them to their max to test the limits of the aircraft.

Being able to manipulate the center of gravity will simulate the aircraft fully loaded with passengers.

Engineers will also put large sandbags in the aft of the plane to add weight and test performance.

On the plane, engineers sit at stations throughout and receive live data from the jet on screens. Here, they can monitor the jet and ensure it's performing as expected.

An engineer told Insider that they will conduct the same test several times a day and that flights can last anywhere from two to eight hours.

When engineers or other employees are traveling on the jet instead of working, they sit in dedicated passenger seats located throughout the plane.

One of the main focuses of the MAX 10 is the landing gear.

Because the MAX 10 is longer than previous MAX variants, the plane needs to stand higher to give the tail more clearance on takeoff so it does not suffer a tail strike.

To do this, Boeing has designed the landing gear to stand taller but still fit inside the same size wheel well.

According to the engineer, the gear expands for takeoff but can compress to make the jet sit lower at airport gates, negating the need for new infrastructure.

The employees actually do tail strike testing as well to prove that the airplane is still structurally sound after a tail strike and the jet is still safe, according to one of the engineers.

In the cockpit are glass screens and heads-up displays. A flight test engineer said that one screen unique to the MAX 10 is a moving map of the airfield that shows where the jet is at when taxiing around.

The MAX 10 is powered by CFM LEAP 1-B engines, which were specifically designed for the 737 MAX, according to Boeing. For Delta, the engines will make the MAX 10 20%-30% more fuel efficient than retiring narrowbodies in the carrier's fleet.

Moreover, the chevron design on the back of the engines reduces noise by 50% compared to the 737 Next-Generation models.

When the MAX 10 is delivered to Delta, the airline will have over 300 Boeing 737 jets in its fleet, which is its second-largest aircraft family behind the A320. Here's what passengers can expect.
