@JT and OS
Is there a limit to the extent of a stopway? I recall 50% of TORA for Clearway but don't recall a similar limit for stop.
I'm just musing over the idea of ASDA being longer than TODA and somewhere like Edwards AFB springs to mind as there is miles and miles of salt flat which could be declared stopway.
It's purely theoretical of course but I'm a little bored today :-)
