I have to confess to reading this thread and then looking at the survey.
It is immediately noticeable that a simple compture graphic simply does not give the information required to make a judgement.
Critically pilots have an immediate reference to cloud height - and to some extent visibility by knowing roughly what height they are at. They also look at the windows at the side - both laterally and downwards and those views offer a lot more information.
Finally we know that the US must be a very ugly country, as virtually all US manufacturers block the view outside with a massive panel - something my aircraft does not have...... So my forward view is at least twice as big!
