Empty weight is the weight of aircraft without taking account of weight of the usable payload here it is passengers,hence it indicates the actual weight of aircraft(its structure,fuel,cabin interiors&crew, galley, cockpit&avionics-computers).
lets see the values of our competitors.
- b737 series aircraft 80,200-98,500 lbs
- a320 family(318,319,320,321) 87,000-107,000 lbs
- crj series(700,900) 43,500 & 47,250 lbs resply.
- fokker 70&100 49,985 lb & 54,100 lbs.
- Bae 146 52,684 lbs.
- Embraer (170,175,190,195) 46,800 lbs-63,900 lbs
the boeing 737-900 & airbus a321 aircrafts have the highest empty weights,this is because they carry comparably large number of passengers than their other series.
the empty weight is considered in the initial stage of aircraft design,hence more empty weight for the given range shows comfort for passengers in way of cabin interior decoration,crew, cuisine,hospitality,on-board entertainment,luxury& increased passenger cargo capacity.
comparing in this way embraer e-series is out with its empty wt of around 50,000 lbs it could carry passengers of max 106 (e-195) with the range of 2000 nautical miles(nmi),also the fokker&bae-146.
the airbus & boeing jets have a tight competition here,but airbus family slightly leads boeing 737s with increased payload capacity of 5%..whether its bet 321 & 737-900 or 320& 737-600/700.
increased passengers for given operating range means a increase in operating economy..
hence A320 family wins here!!
