To determine the most powerful aircraft what you need to do is take the total thrust and divide it by the total number of avg. seats on the aircraft...
So for Delta Air Lines Fleet...
727- Total thurst= 43,500lbs total avg seats=145
....Total thrust per seat 300lbs
737-200- tt= 29,000lbs tas=119
....total thrust per seat 243.6lbs
737-300- tt= 44,000lbs tas=128
....total thrust per seat 343.75lbs
737-800- tt= 48,000lbs tas=156
....total thrust per seat 307 lbs
757-200- tt= 83,400lbs tas=182
....total thrust per seat 458lbs
767-200- tt= 96,000lbs tas=204
....total thrust per seat 470lbs
767-300- tt= 100,000lbs tas=252
....total thrust per seat 396lbs
767-300ER- tt= 120,000lbs tas=195
....total thrust per seat 615lbs
767-400ER- tt= 126,600lbs tas=287
....total thrust per seat 441lbs
777-200- tt= 184,000 tas=277
....total thrust per seat 664lbs
MD88- tt= 40,000 tas= 142
....total thrust per seat 281lbs
MD90- tt= 50,000 tas= 150
....total thrust per seat 333lbs
MD11- tt= 186,000lbs tas= 260
....total thrust per seat 715lbs of thrust
CRJ Comair- tt=18,440 lbs tas=45
....total thrust per seat 409lbs
SO the MOST POWERFUL AIRCRAFT
IN DELTA AIR's FLEET
IS THE
MD-11 by 51 more pounds of thrust
ALL INFORMATION CAME EITHER DIRECTLY FROM DELTA
OR FROM AIRLINERS
OF THE WORLD by STEWART WILSON...Any questions I would be happy to answer.
