NARROW BODY REGIONAL AIRCRAFTS-MTOW COMPARISON.

Maximum Take-Off Weight (MTOW) is the weight of aircraft at which a pilot is permitted to perform take-off operation, hence it indicates the real weight of aircraft at the instant of take-off(it includes payload(passengers), structure,fuel,cabin interiors&crew, galley, cockpit&avionics-computers).
lets compare now!! 
  • b737 series aircraft 144,500-187,700 lbs
  • a320 family (318,319,320,321) 166,000-206,000 lbs
  • crj series(700,900) 43,500 & 47,250 lbs resply.
  • fokker 70&100   80,998 & 101,000 lbs.
  • Bae 146  93,000 lbs.
  • Embraer (170,175,190,195) 85,000-115,300 lbs

if u have a look at previous wt comparison u can get a clear picture that there is a rise of 45.5% wt in all aircrafts,this is due to passengers.

here too boeing 737-900 & airbus a321 aircrafts have the highest empty weights,for the same reasons said in above post.

The MTOW is considered in the initial stage of aircraft design,more empty weight means more strength of the aircraft structures and maneuver performance;withstand more g force in climbing and turning. i.e to simply put a hard-working bull; but at the same time a more power means more fuel hence reduced range and fuel economy.

in civil there is a design tactic 50% weight of aircraft in structures should be dedicated to payload.
unless there is 50 % share in payload weight its waste to carry such a heavy take-off weight!

for all the above aircrafts this formula is correct!!
hence in mtow all share the same vote!!!
