Wingspan 124 ft 10 in (hereafter rounded to 125 ft) Length 155 ft 3 in (rounded to 155 ft) Tail height (with landing gear extended ) 44 ft 6 in Fuselage Width 12 ft 4 in (rounded to 12 ft ) Max fuel capacity 11,489 gallons Max range 4449 miles Max take off weight 255,000 lb.
The following specifications were not directly available from any source I could find, but I calculated them based on the above figures, after measuring diagrams and photos. Exact accuracy cannot be guaranteed, but they are close and are sufficient for this analysis.
Tail height (without landing gear extended) 35 ft Fuselage height (without landing gear extended) 14 ft 6 in (7 ft 3 in above wings, 7 ft 3 in below wings)) Length of each wing 56 ft 3 in Engine diameter. 9 ft. 6 in Engine length 11 ft 6 in Position of engine mounting on wing. Outer edge of engine 25 ft from where wing joins fuselage. Width of each tail fin 15 ft 6 in Total tail fin span 39 ft (fuselage is narrower at this point) An estimated 5 ft of engine is below fuselage level, making the total height of the aircraft without landing gear extended, 40 ft.
You’ll find the calculations throughout this article easier to critically analyze, if you write down the above figures before continuing.
