Le Pingouin
Not going to hijack this thread with details. But, for reasons that the ATC was either unable to be aware of weather or was maybe not fully appreciating the difference in weather that a light aircraft can tolerate vs a jet or (dare I say it) even laziness. It does happen. If the pilot responded with a request or requirement, I maintain confidence that the controller would react with diligence. But not all pilots do this. Aside of the instances where I have first hand knowledge, there was a case a bit like this that the ATSB was questioned about in Senate estimates last year.
But, the common enemy in this thread is a regulator which imposes regulations that cannot be complied with because the required equipment is not commercially available.
