I've done a little research on UK airports, re the use of stopways, probably a bit late. It's not systematic, just a quick look at most of the Type A charts.
The good news is that most, including Bristol, declare TORA and ASDA as the same, so there is not a problem at those airports at least so far as stopways are concerned.
The poor one I referred to earlier still exists; but I feel that I should correct any impression that stopways that do not meet the requirements fully are a common problem.
But this does not alter my last post, above. There are variations from the required minimum standards, in all areas, at many airports and I do not believe there is sufficient pressure on the operators to put them right.
