What is the difference between boeing 777 and 747

As such, many have begun to wonder which is truly better, the or ? Both aircraft have also had very successful careers as cargo aircraft, mostly due to their size.

Many former passenger s and s have been converted into freighters and have continued their service life as such. Of the largest aircraft currently flying today , four of them were produced by Boeing. This list includes the Boeing -derived Guppy line of freighters, the standard , standard and the derived Boeing Dreamlifter.

Several previous Boeing aircraft were among the largest of their times too! Boeing has continued this trend with both the and , although the is noticeably larger than the , just by looking at it! Initially, this was not meant to be the case. The was designed to be larger than its predecessors a task it accomplished very well. Instead, it was meant to be a large, long range aircraft that could fill the market that the was too big to fill. Before we can compare both the and , we first need to know a little background about both aircraft.

In particular, we need to know why they were designed to be so big and what other purposes they serve! In , the USAF was looking for a large aircraft that could act as a cargo aircraft and occasionally as a troop transport, in an attempt to replace their ageing Lockheed C fleet. As with other aircraft manufacturers of the era, Boeing submitted their design. He wanted something bigger. Remembering their failed cargo aircraft from , Boeing took the project off the shelf and redesigned certain parts of the aircraft to fit the airline industry.

After showing Juan Trippe the revised schematics, the was born. The would first fly on February 9 , conducting a series of flights to test the aircraft. A year later, in January , the would be entered into service with Pan Am, before being entered into service with other airlines. The introduction of these second generation jets posed an issue to Boeing. Whilst the and had taken over the roles of the and DC-8 respectively, as well as many routes, many new gaps had appeared.

Airlines had begun to seek a new type of aircraft, larger than the and , but smaller than the Boeing attempted to counter this by making the a shorter variant of the , all to no avail. As such, they realized that they had to create an aircraft that was smaller than the , but had better economics that the DC and L As such, Boeing designed a new aircraft completely from scratch.

This aircraft was originally a trijet, but once ETOPs had been implemented, it was a twin jet. Eventually, this would become the This aircraft would first fly on June 12 , and gain FAA certification later on that same year. The most common variant of the is the , currently serving as both a cargo and passenger aircraft. However, primarily as a passenger aircraft. After looking at the specs of the two aircraft, it may be tempting to call a winner immediately.

On occasion, Boeing has had issues with the safety records of some of their aircraft, including the recent MAX. In fact, of all the aircraft flying today, you are least likely to die on a as it is one of the safest aircraft currently flown.

As of the time of writing, the has been involved in aviation incidents. In this, there have been 63 hull losses, which has resulted in fatalities. Sadly, many of these crashes have been very high profile, mostly due to the death toll. Luckily, many of these crashes occurred with older variants of the , including both the and With the intention to overshadow its predecessor and competitors, the products designed to fly over the Pacific certainly consume more fuel than the variants.

In fact, the variant from Boeing only offers half the amount of power that is produced by the twin engines of the x product line. The example can be seen in the performance of the MAX that was banned for two years in March after two crashes. The MAX plane crashed in the Java Sea shortly after takeoff from Jakarta in Indonesia in October , and the same model crashed in Ethiopia in March that caused the death of a total of people.

Coming back to the vs comparisons, the Boeing is one of the safest aircraft in the aviation industry. However, the older retired variants of the line, like and , were involved in aviation incidents, including the 63 hull losses that resulted in 3, fatalities. The issues were later fixed on the latter variants from the product line like s and s, completely redesigning the variants.

Similarly, the product line, which was designed with the original purpose of replacing first and second-generation jetliners from the Boeing family, does its job quite perfectly. The products from Boeing has been involved in only 29 aviation incident, including the eight hull losses that resulted in fatalities, making it statically safest aircraft in the aviation industry.

Furthermore, the new X variants from the products line are expected to be even safer in the lines, introducing a new level of safety in the industry.

After everything is said and done, the pricing of the products also determines whether they are worthy of the price tag after evaluating their aspects and performance. The latter version of the product line certainly costs more than the previous predecessor.

However, technological improvements, including eco-friendly, future-proof, and fuel-efficient features,, make them worthy adversaries. So, betting on the cutting-edge product line of the variants may be a better deal than outperforms the variants in performance, fuel, efficiency, safety, and specifications. Pin it 0. Share 0.

When it comes down to these two aircraft, no doubt they are both heavyweights in their respective rights, but what differences do they hold that set them apart from each other?

For starters, the , like other long-range jets of its day, was built with four engines while the has only two, albeit large engines. On top of this, they are cheaper to run than even later model planes. In this regard, it would be cheaper to fly in a than Another distinguishable difference is that the was designed with two decks while the only has one. Down to the landing gear, the almost looks like a caterpillar with its six wheels for each of its two main landing gears.

The on the other hand has four main gears with four tires on each. Still on the wheels, the has five sets, while the has only three.
