Hi!
Using a dozen tables of performance data for the Falcon 50 (from the freechecklists.net file linked in this forum) I've put together an MS Excel tool, which allows for quick calculation of takeoff thrust, takeoff and landing speeds and distances. Hopefully this would make performance calculations a little less tedious.
It's now available from the AVSIM Library: https://library.avsim.net/esearch.php?DLID=221011
Let me know if you find any issues or have any suggestions. Enjoy!
Michael
