Well, as a rule of thumb, you can figure than a twin engined commercial jet
transport is designed to get in and out of La Guardia.  That airport is our
limiting design case for a lot of stuff.  :-)  The 747 uses somewhere
around 8,000 to 10,500 ft of runway depending on mission length.  I can't
speak to tri-jets, we don't do them anymore.  :-)

BTW, there is no economic benefit to using less runway than is available at
La Guardia.  There is a niche market for the really short runways, but the
compromises you would be forced into drives down your cruise performance
and therefore your operating costs go up.  The traffic out of those small
runways is pretty thin.  Look at the sales of BAe 146s, and see what I
mean.
