the normal deal involved a suitable FMS.
Interesting, but why?
Aeroengineer1,
Boeing considers narrow runway data as an AFM appendix, it therefore costs money. If you are a Boeing operator you can ask your tech rep for a non-operational version of the STAS program for test purposes.
AFAIK, the Australian CAA are the only ones who require performance data to be based on the runway width.
