Assumes 4704 sq ft wing area, aspect ratio 9.2, Oswald's "e" 0.86, typical sfc 0.587lb/lb-hr and 7% compressibility drag at M0.83, Cdo being 0.014 (777 being 0.013 and 747 being 0.015).
Sfc is not constant and neither is compressibility but it is good back of fag packet stuff at intvu if I did the XL spreadsheet aright. About what I'd expect, 10.5 tonnes per hour ToC and 6.5 tonnes/hr ToD on a long haul.
My pleasure... The Enicalyth
