Boeing 777 Specs

As you will see in our Boeing 777 Specs tables below, this flagship aircraft of the Boeing stable is an impressive giant twin. Taking the flagship role over from the Boeing 747, Boeing has grown this modern airliner from the Classic series in the mid-1990s to the Boeing 777x series which first flew in January 2020.

The Classic series comprised two main passenger versions plus a Boeing 777 Freighter version. Two main Classic passenger versions are the Boeing 777 200 and the Boeing 777 300 variants. Although their air-frame measurements such as wingspan, wheel track and tailplane are the same, the major difference is the fuselage length. Being significantly longer in the fuselage, the Boeing 777 300 outstretches its sister, the 777 200, by 10 metres, comparatively adding a far greater passenger capacity.

The Boeing 777 was the longest aircraft in the world..

The Boeing 777 300 was the longest airliner in the world until the introduction of the Airbus A340 600. Boeing is currently in the final stages of testing the brand new Boeing 777X model. This updated 777 was due to go into service in 2020, however, due to updated certification requirements and the Covid19 travel downturn, it is more likely that the 777X will be delivered in 2023.

Boeing 777 Specs 200LR and Boeing 777 300ER

Boeing introduced longer-range versions of the Boeing 777 200 and Boeing 777 300 in response for airline demand for this aircraft to service long-haul intercontinental routes.  

On 12 December 2011, Boeing received ETOPS 330 approval for the:  Boeing 777 200LR, Boeing 777 300ER, Boeing 777F and Boeing 777 200ER equipped with General Electric engines.  This means that these aircraft are certified to fly over water provided they can fly to the nearest available suitable landing spot in under 330 minutes, flying on one engine only.

With improvements in the dependability of jet engines that has allowed these longer overwater flights, comes the leap forward of the viability of long haul twins. The adage of four engines for over water is less relevant as we have seen the demise of the Airbus A340, the Boeing 747 and now the Airbus A380 as well. For this reason, Boeing is placing their money on the Boeing 777X to take them into the future.
