Hi all
Just to finish off my original question - info from the maintenance dept shows that 230kts is the point after which (if leading edge devices are fully extended) inspection(s) by maintenance are required so obviously comes down to a load limit/airworthiness question.
Phase 1 or 2 inspection (or a mix) depends on speed over 230kts - but that's another thing altogether.
Thanks for playing!
Cheers
