Boeing 747 8 Specs.
Boeing 747 8 Specs, shown below will illustrate how the Boeing 747 8 Freighter and 747 8 Intercontinental are the largest iterations of the classic Boeing 747 model which has ruled the skies for four decades. It is the largest and heaviest aircraft produced in the United States.
The new 747 8 is the next generation of this iconic aircraft and benefits from technologies and enhancements that were used to create the Boeing 787 Dreamliner. New wing technology, engine technology and also increased length enables a larger passenger or cargo payload to be carried.
As we have seen, however, like the Airbus A380, the 747 8 has come to market at a time when interest in large 4 engine jets is waning. The day of the giant twin-engined jets is at hand, fairly well sealing the doom of the jumbos. Fortunately for Boeing, the original design of the Boeing 747 with the cockpit located in the top bubble allowed for a nose door to be installed. Initially, it was not assumed that the passenger version of the 747 would catch on, so Boeing took an each-way bet and ensured the design would fit freight airliners needs, should the passenger version fail. By having the cockpit raised above the main deck, cargo can therefore be passed longitudinally through the nose door along the main deck. This allows for longer items to be easily loaded. Airbus, with their A380, do not have that same luxury.
…. insertion of an extra 5.6 metres….
Below you can see where the extra length was inserted on the 747 8 Intercontinental passenger version as well as the 747 8 Freighter version. The insertion of an extra 5.6 metres (220 inches) of length as compared to the Boeing 747 400 is slightly different for the 747 8 Intercontinental as compared to the 747 8 Freighter. For the 747 8 Freighter, this is done by inserting an extra 4.1 metres of fuselage length at the forward wing root. The purpose for this is to do it behind the upstairs bubble and thereby not increase the bubble size but rather make it smaller, more reminiscent of the Boeing 747 100 and Boeing 747 200 series. The 747 8 Freighter does not carry passengers, therefore, the bubble is redundant other than the house the cockpit. The 747 8 Intercontinental, on the other hand, has the forward insertion of 4.1 metres (220 inches) placed forward of the wing root so that it takes in the upstairs bubble as well. This way the upstairs bubble, as well as the main deck, are extended, increasing the seating capacity dramatically. By how much exactly depends on the airline and what seat pitch they want to apply. Both the 747 8 Freighter and the 747 8 Intercontinental have an insertion of 1.5 metres behind the wing root in the same place.
