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..
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
Longer-range versions of the Boeing 777 200 and Boeing 777 300 were introduced by Boeing in response to 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.
Boeing 777 longer-range variant dimensions.
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. The reception by the public and equally the prospective customers at the 2021 Dubai Airshow was very positive, especially when Boeing wowed the crowd with some very high-performance displays.

hi, very informative and nice structarized content. but I came here to look for SFC and Cruise thrust for 777-300er. if possible need answer in lbs unit. waiting for ur response. thanks 🙂
Hi, I was wondering if you could answer a few questions for me. All of the questions are for the Boeing 777-300er
1) What is the minimum speed it needs to take off?
Answer: Like many things in aviation, there isn’t one single answer to that question. The factors that need to be considered are the weight of the aircraft, the air pressure on the day, and the height of the runway above sea level which affects air pressure. The speed of course is airspeed not speed across the ground. If there is a strong headwind down the runway, the ground speed at take-off will be less. If there is no wind then the airspeed and the ground speed will be the same. Typically that speed is between 130 – 160 knots (241 – 296 KPH).
2) What is the length of runway needed for this plane to take off?
Answer: The length of runway required for takeoff is governed by the same conditions as above for the takeoff speed. Weight, air pressure and altitude. Additionally, wind speed and direction play a large part here. If you have a strong headwind already passing over your wings before you even start your takeoff run, you will achieve your required airspeed much sooner and therefore need less runway. Of course, the less favourable the headwind is, the longer the runway required will be.
3) What is the maximum landing speed?
Answer: Once again an answer with many considerations such as aircraft weight, air pressure and altitude of the runway. Typically the landing speed would be between 110-130 knots(241 – 204 KPH).
4) What is the length of runway needed for this plane to land?
Answer: Here we need to consider the weight of the aircraft, down to calculating the weight of the fuel that is left in the tanks after the trip. The altitude of the runway will determine the ability of the reverse thrust braking system to work effectively due to thicker or thinner air. The surface of the runway whether it be wet or dry will determine the effectiveness of the wheel braking system. Wind will determine how fast the aircraft is travelling across the ground on touchdown and how long it will need to brake thereafter. The minimum for these large jets would sit around 2,500 metres(8,202 feet) plus RESAs(Runway End Safety Areas) which are surfaced areas at the end of the runway to capture possible runway overruns.
Thanks for any help you can give!
What is the minimum runway width for the varying B777 models to conduct a 180-degree turn on the runway, in the event of an emergency and there are no tow bar/tugs. Meaning, if one of the B777 had to do an emergency landing/divert to an airfield with only 150′ wide runway and no tug/tow capabilities, would the aircraft be stuck?
Hi Chris,
thanks for stopping by. Regarding your question and any others you might have about the Boeing 777, I believe you should be able to find it in this comprehensive manual below.

hi this is great informations ..
i have a project and i am working on the bulkhead seat of boeing 777 i am trying to design something really useful so i need all the dimension of bulkhead seat everything about that seat in boeing .. please if you know any thing any dimension tell me that would help so much
Hi,
thanks for stopping by. The seat dimensions are really down to the ordering airline. They have many choices of seat type, pitch(the distance between seats front to back) depending on their intended use of the aircraft. So I guess the question to ask is, what aircraft are you desinging, does it belong to a certain airline? If so, perhaps that airline may give you the info you need.
Good luck.
Peter
Pingback: The Differences Between the Boeing 777 Variants - Aviation for Aviators
Hi
I was wondering what the difference is when you see a 777-3DZ etc.
For some reason, the lettered variant codes always seem to look longer, but they must be the same if only two variants were ever made (prior to the 779/x)
Usually the 772/773 are standard, but wondered if the letters referred to something specific for that airline, such as additional fuel tanks, specific cabin layouts, or custom/specific ordered additions to the variant? So the 777-3DZ is a long range 773 with an additional fuel tank and 20 seats removed to reduce weight and increase range, and so on…
Thanks for a very informative page!
HI,
thank you for liking the page. You’re absolutely right, the base models are the 777-200 and 777-300 prior to the 777X. The letters that may appear instead of the zeros on the 200 or 300 denote specific bespoke features requested by an airline that may be a departure from the standard offering.
Cheers Peter
