OverRun ..
I am not aware that CASA (I think they were DOT-ATG at the time .. ) released a report on the work done.
The concerns were purely operation .. regarding
(a) CL deviations during a failure for reject/continue cases
(b) worst case considerations for the wet runway case
(c) late final landing manoeuvring following a misaligned letdown and a side-step manoeuvre .. wonderful to watch from the ground ..
The main thing to come out of the work was that the lateral deviations can be a bit hairy depending on the proximity to Vmcg at Vef and, of course, depending on crosswind. The general concensus was that some aircraft ought not to be operating on the ICAO standard widths as a critical failure could produce useful journalistic copy on page one.....
We still have to catch up for an ale so I can regale you then with stories of the work done ....
