Boeing 767 Vs. Boeing 777- (Detailed Comparison)

by Logan
A detailed comparison between the two aircrafts

There are many types of engines that are used in an aircraft. They differ in terms of the sizes of engines and winglets. Boeing aircraft refers to any aircraft bearing the designations “737”, “777”, or “787”.

People usually don’t know the exact variations among these aircraft, they confuse one another. Therefore, we need a great amount of research and information to know the contrast between Boeing 777 and Boeing 767.

The engines on the 777 are much larger than those on the 767. The 777 is significantly longer and has massive raked wingtips with no winglets. The 767, on the other hand, has smaller, more 737-like wings that are larger, and some have winglets while others do not.

Today I’ll be discussing the main differences between them along with relatable information that’ll help you know the contrast in a better way.

So, let’s get started.

How Can You Differentiate Between Boeing 767 And Boeing 777?

There are many differences between the sizes of these aircraft. The engine is quite different along with the design of the winglets. Some of the physical differences are :

The 777 can fly much farther and carry more passengers than the 767. It is also Boeing’s first aircraft with a fly-by-wire system. These are just a few examples of the differences.

The 767 is a mid-market widebody designed to fly medium to long-haul flights with 250 or so passengers. In its current configuration, the 777 is a large-capacity airliner that flies long and ultra-long distances.

In addition to that, the 777’s production began roughly a dozen years after Boeing co-developed the 757 and 767. Boeing considered simply making a longer 767, but the airlines demanded a larger plane with significantly more passengers.

It is observed that the overall design is consistent.

Which One Is The Most Secure Aircraft?

We can easily identify them by knowing their unique features. I’m assuming the primary structure is similar because Boeing has used it successfully for aluminum aircraft ranging from the 707 to the 727, then 747, and the 757/767.

The passenger windows are most likely the same as they were on the other six Boeing planes.

The key point is that bigger engines became available that were also very reliable, allowing a large twin-engine aircraft to be built that could fly a large number of passengers a long distance, requiring at least an ETOPS of 180 minutes and now approaching 360 minutes.

And you should be safe because Boeing took the best of the 757/767 overall design and applied it to the 777’s structural and mechanical philosophy.

To summarize we can say that, the Boeing 777 is one of the most secure aircraft available.

How Can I Identify An Aircraft To Be 767 Or 777?

To identify them, one should know their characteristics and unique features.

The first difference from the physical overview is that b767, it’s a quite old airliner than the b777. Taking about both seating capacity, B767 has 244 seats according to UK and Europe standards while the other hand, b777 has 314 to 396 seats.

Moreover, because of their respective launch dates and years, they have a huge difference in their range even, b767 has a range of up to 11,090 km while the b777 has up to 15,844 km.

From the interior's point of view, it differs from most the airlines in their choice.

What Are The Different Variants of the b767 And b777 Series?

The first b767 came into production in 1981 and had its introductory flight with United airlines, while b777 came to production more than a decade later in 1994 and had too introduced by United airlines.

The b767 series has the following variants:
  • 767, E
  • PEGASUS KC 46
  • The KC 767
  • E-10 MC2A Northrop Grumman
While those of b777 are:
  • The 777-200
  • er 777-200
  • the 777-200 LR
  • 300 er = 777
  • 777-300

Thus, the B767 series starts at $160,200,000 per unit, while the B777 series starts at $258,300,000.

What Is The Appeal Of The Boeing 767?

It was a wide-body aircraft with a large passenger capacity, two engines, a long-range capability, and two pilots instead of three at a time when three-pilot cockpits were common.

“Glass Cockpit” Design “as well as a navigation system. Airplanes will not change much until “anti-gravity” is invented and “machines are created (IMO). 

The last major “game-changer” resulting in speed and reliability was the transition from piston engines to jet engines. It was followed by Global Positioning Navigation in all modern aircraft.

The airframe has proven to be dependable over time. The 767 is one of the few planes that has found a “sweet spot” in terms of range, payload, and operating costs. The DC-3 was most likely the first “sweet spot” airliner.

The first truly versatile widebody twin was the Boeing 767. The A300 was a fantastic plane, but it tried far too hard to compete with the big boys, 747s and DC-10s. 

Overall, the 767 carved out its niche as a cost-effective, two-crew widebody ideal for transatlantic flights, helped by its similarities to the 757.

Boeing 767 Vs. Boeing 777- Tabulated differences

The Boeing 767 And The Boing 777- What’s The Difference?

The 777 is a larger plane; even its smallest variant, the 777–200, is larger than the 767’s largest variant, the 767–400. The 777–200 is 64 meters long, while the 767–400 is 61 meters long.

However, the most popular variants of each aren’t even close in size. 

The 767–300ER is 55 meters long, while the 777–300ER is 74 meters long. Furthermore, they are not used in the same market.

As a passenger aircraft, the 767 is in decline. Delta will retire their 767–300ERs by 2025, Air Canada Rouge is said to retire them in 2020, and so on. The 767 is an excellent aircraft for flights from New York to Dakar.

Its success continues, particularly in the freighter market, where FedEx still has orders to fill.

The 777, on the other hand, is still hugely popular and will be for decades. The 777x will enter service in a few years, while many airlines will continue to use the 777–200ER and –300ER.

It is an excellent aircraft in terms of range, fuel efficiency, and passenger capacity. As a result, it is an excellent fit between cities such as New York and London, Los Angeles and London, and New York and Tokyo, to name a few.

Why Is The Boeing 767 Less Popular Than The Boeing 777?

Boeing 767 is less popular than the Boeing 777 because it is older, requires more maintenance, and is less fuel-efficient. It received its first service certification in 1982.

Similarly, a 1982 passenger car would outperform a more modern one in terms of operating costs, maintenance requirements, and fuel efficiency.

The 767 is still a fantastic plane, but times have changed, and cost-per-mile per passenger is now the primary motivator behind airline fleet purchases.

What Is The Crash Record Of Boeing 777?

The Boeing 777 has gone through at least 31 aviation accidents while. Among these accidents, 5 losses took place in the air while 3 surfaced at the landing moment.

Boeing 777 is known to experience 541 fatalities and 3 hijackings. One of the most famous accidents of the engine was when it crashed into the Indian Ocean.

With 12 crew members and 227 passengers, the crash resulted in a total of 239 fatalities. These bodies were not recovered.

Crash Record Of Boeing 767

The Boeing 767 has been declared an overall safe aircraft. Nonetheless, it suffered its first crash on 23 July 1983, the engine crashing near Gimli, Manitoba.

One crash took place in the USA, while the other was reported in Thailand. The engine recent crash took place on 23 February 2019, in Trinity Bay, about 30 miles southeast of Houston.

Conclusion

In conclusion, the Boeing 777, 767, and the Airbus A330 are three of the most-used, two-engine widebody jets flying around out there. They look similar to the untrained eye. But some differences help make them easy to distinguish.

The Boeing 777 is considered the largest of the three aircraft. Its most distinguishing feature is its size. It is significantly larger than A330 and b767, therefore known as an enormous jet.

While the other one, 767 is smaller, especially the 300 ER.

As already discussed, the variables give us a broader look at the number of engine and individual passenger capacities.

The engines are very large and as wide as the fuselage of a 737. Although, there are no winglets associated with B777 some 770s and A330s have winglets. A330s and B767s only have two sets of wheels while Boeing 777 has three sets of wheels.

Hence they both are way too different from each other in terms of size, winglets, cruise speed, width, and wheels. You can easily identify them by going through this article.
