Now I know that some feel that a Citation Excel and Brasilia have little relevance to a 744(although John Tullamarine has corrected that notion), for those that relate only to size, I did find this interesting statement...
"In the C-5, we took a 250 foot "line-up" penalty and a 750 foot penalty for rolling take-offs, i.e. the assumption was 250 feet to line-up off the taxyway and an additional 750 feet was added for rolling take-offs."http://www.pprune.org/tech-log/24077...ml#post2800425
