Maybe I was too hurried when posting. I got similar replies in the Safety & CRM forum (where I cross-posted for, hopefully, more pilot responses) which is entirely understandable.
The survey is for an exam paper which forms part of my flight training. I have a CPL IR/ME (frozen ATPL) and also have a background in ATC training (Eurocontrol ab-initio and simulator pilot) and aeronautical charting.
I want to investigate whether pilots and controllers have the same views or different views regarding their roles as well as operational procedures. Are pilots taught enough about how ATC operates? Do controllers know what the priorities of the pilots are? Are both sides on the same page regarding how to operate the transponder or what happens during an emergency descent? Is there an "us-and-them" attitude amongst some pilots and controllers?
