FL400, TCAS, please, if you've taken my comments as a personal dig at the controllers I sincerely apologise. I do not, in any way, seek to impugn the professionalism of individual controllers. On re-reading my posts I can see how that could be assumed.
I know you're doing your best with what you have. Sadly what you have is not good enough by world standards.
Ever complex procedures for pilots to comply with in order to make your job easier because of inadequate resources, manpower, training, recency or facilities, is the thrust of this thread. We are on the same side.
