Boeing 747 8 Specifications.

The Boeing 747 8 Freighter and 747 8 Intercontinental are the largest iterations of the classic Boeing 747 model which has the 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 to enable a larger passenger payload to be carried.

…. 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.

    • Hi and thanks for stopping by. You’re right we did not have that information. We have now rectified that and you will see the line with Operating Empty Weight.

  1. Are the current B747 -400 series towbar able to use or need new spec for the towbar.

    • Hi Jerence,

      Interesting question. It seems that the same equipment can be used for both the 747-400 and the 747-8. An example is the Tronair A003830D which is rated for both.
      This of course is not a definitive answer and any decisions about actual equipment purchase should be based on information direct from the supplier.

      Cheers Peter

    • Hi Mark,

      thanks for stopping by.

      We can certainly share that with you. So there are of course some variables with this data which are dependant on whether the aircraft is loaded or empty. The measurements below refer to a minimum and a maximum. Maximum is when the aircraft is empty and therefore rises up on its suspension and tyres. Minimum is, therefore, when the aircraft is fully laden.

      For them main deck, there is a difference between fore and aft, as the aircraft sits slightly nose down on the ground. In this case we have specified Front and rear.

      Top Deck height: Minimum – 7.56 Mtr / 24 ft 10 in
      Maximum – 7.90 Mtr / 25 ft 11 in

      Main Deck: Front, Minimum – 4.78 Mtr / 15 ft 8 in
      Maximum – 5.16 Mtr / 16 ft 11 in

      Main Deck Rear, Minimum – 4.95 Mtr / 16 ft 3 in
      Maximum – 5.32 Mtr / 17 ft 5 in

      I hope this helps.

      Cheers Peter

  2. 747-8 leaves sdf every day at extremely close to 998,000 even seen it a 1,000,090lbs . Its amazing

    • Hi Mike,

      Good question. The answer, like so many things in aviation, has some variables built into it. Firstly, the minimum height of an engine above the ground must be sufficient to allow clearance in all stages of maneuvering. It must also be sufficient avoid any water ingestion on wet runways. This is a integral part of water test conducted on new airliner types.
      The next variable is the load of fuel and payload. As you can imagine, a full aircraft settles down its suspension just like a car. The result of course is that engines are closer to the ground. Even more so with full fuel as the wings droop down.

      So in answer to your question, we must consider the in board and out board engines sepaeately and for each a maximum and minimum clearance.

      In board engines. Minimum Clearance:0.73 M (2 Ft 5 In). Maximum Clearance 0.9 M (3 Ft 3 In)
      Out board engines. Minimum Clearance: 1.9 M (6 Ft 3 In). Maximum Clearance 2.1 M (6 Ft 11 In).



    • Hi James,
      Thanks for stopping by. There are so many variables in calculating these outcomes. Maybe there is a weight and balance calculator for this aircraft somewhere online.
      Best of luck.
      Cheers Peter

  4. What is the area of the wings?
    What is the fuel consumption of the plane?
    What kind of fuel does the plane use?

    • Most of the plane is made from new aluminium alloys, while it also incorporates graphite composites in the rudder, spoilers, flaps, and other areas. According to Boeing, “the materials are more durable and better able to resist corrosion and damage, which reduces maintenance and increases the time an aeroplane is available and productive.”

    • Hi Akash,

      the best way to work that out would be to take the wingspan, deduct the fuselage width and then divide by 2. Bingo. 🙂

      Cheers Peter
