When Will The Boeing 777X Come Into Service?

Boeing installed the engines on its first 777X flight test aircraft earlier this month. The aircraft is scheduled to roll out in February, and its first test flight is expected to take place in the second quarter of this year.

Flight Tests

All aircraft must go through extensive flight tests before they are certified. They are operated in conditions that are frequently more extreme than the ones they will encounter in revenue service. The aircraft are tested all over the world.

Boeing’s flight tests typically include simulations of a variety of failures, as well as takeoffs and landings at low and high elevations, extremely cold and extremely hot temperatures, and in high winds.

The 777X’s GE9X engine has already passed its first flight test. Last March, a GE9X engine was mounted to a specially designed pylon on a Boeing 747 replacing one of its engines. This test was successful, and now the first flight test of the aircraft is just around the corner.

According to Boeing, “three additional flight test airplanes will be built after flight test #1.”

With all this testing coming up, when can we expect the Boeing 777X to come into service?

Originally, Lufthansa was slated to be the launch customer of the 777X. However, things have changed, and the first 777X aircraft is expected to be delivered to Emirates in mid-2020.

Accordingly, we are likely to see it put into service in the second half of 2020.

Currently, Emirates is the largest 777X customer. It has placed orders for a total of 150 aircraft.

In addition to Emirates, ANA, Cathay Pacific, Etihad Airways, Lufthansa, Qatar Airways, and Singapore Airlines have ordered the aircraft. Nonetheless, the last orders for the aircraft were placed by Singapore Airlines back in 2017. Even though other airlines are reportedly considering the purchase of the aircraft, no additional orders have been received by Boeing.

The Boeing 777X

The Boeing 777X will be Boeing’s largest twin-engine aircraft. It will feature composite wings with folding wingtips. The folding wingtips are necessary due to the aircraft’s large wingspan of 235 feet. Furthermore, the world’s largest turbofan engine will be installed on the aircraft. GE Aviation’s GE9X engine is about the same size as the fuselage of a Boeing 737. It is the most fuel-efficient engine produced by GE to date.

The 777X-8 has a range of 8,700 nm and 350-375 seats in a 2-class configuration. The 777X-9 has a range of 7,600 nm and 400-425 seats in a 2-class configuration. The list price of the aircraft is $360.5 million and $388.7 million respectively.

Additionally, as Simple Flying has reported previously, the 777X’s interior will be open and airy.

Due to its capacity, range, and fuel efficiency, the aircraft will be perfect for high-demand, long-haul routes.

We are definitely looking forward to its entry into service next year.
