Pilots are required to be able to come up with these numbers, by hand from a paper chart.

Actually it is not that difficult so I would think for real ATPs with thousands of hours it must be a piece of cake. 747-400 takeoff data is for example available for selected few runways on the PMDG Wiki pages courtesy captain Jon B. I actually wrote a brief explanation how to use them. :(

The former TWA new hire manual has all of the landing data for each airport they serviced, to and from, with expected landing weights, +/- depending upon conditions at hub locations.Pretty much a canned flight profile that the engineer did his data cards from and double checked with the load sheet.
