Wow, what a response, and not entirely what I had expected. I really was trying to point out to ATC that pilots don't always do what we ask, despite the ramifications of all that may follow. What I don't know is how often this is occuring. Trying to see the wood for the trees, I can see possible reasons why restrictions wouldn't be passed on by a pilot, but from the seat where I'm actually being able to observe the cascading consequences of what may seem a small omission, I also really wanted to stress to a small number of pilots that there will be a reason for the instruction and it could be important. Why gamble that it isn't?
We are all a team and we really do need to have dialogue and this is probably the best method I have at the moment, so I'm sorry if I ruffled a few feathers, but I hope that someone, somewhere, ATC or pilot thinks about this for a moment. This IS teamwork, isn't it?
