Aircraft empty weight vs number of passenger seats
Aircraft manufacturers keep producing new designs that are much more fuel efficient than older ones, using lighter materials (composites), better aerodynamics (new wings and winglets), more fuel efficient engines and other methods as well (lack of bleed air for packs in the 787 for example).
I would like to take a look at the weight savings aspects, by comparing the Operating Empty Weights of actual fleet aircraft and dividing it by the number of passenger seats installed in that particular configuration, the see how many Kilograms of aircraft empty weight it takes to haul one passenger. All other things being equal, the lightest aircraft should be the most fuel efficient. Of course long haul aircraft are built heavier than short haul aircraft.
Please post the actual Operating Empty Weight of your aircraft and the number of passenger seats installed in it, and divide the weight by the number of seats. We'll see which are the heavier aircraft and which are the lightest. Am interested in having all airline types, from older 737-200s, 737-200s, to MD-80s, right up to the 787s and Emb 195s.
Are the older types like the 727-200, MD-11s and 747-400s that much heavier than more modern aircraft such as the B777, A330, the Emb 195 and the 787 ?
How does a 737-800 compare in empty weight per Pax to an Airbus 320 ?
How does a 747-800 compare to an A-380 ?
Of course the configuration (number of seats) varies greatly on the same aircraft type from one operator to another, and that will change the results, but hopefully with enough data, we will be able to make valid comparisons.
Please post the Operating Empty weight - Revenue (including crew but not the catering) of your aircraft and the total number of passenger seats, and divide the weight by the number of installed seats.
Example :
Airbus 330-200 OEW 118,500Kg, 342 seats (12+330) = 346.5 Kg/Pax
Airbus 330-300 OEW 120,400Kg, 342 seats (12+330) = 352.0 Kg/Pax
