e.g The primary task of a VCR controller is to look out of the windows to observe the traffic he/she is providing a service to. Thus any feature which reduces the need for the controllers head to be down and eyes to be 'in the office' must be a safety advance. EFPS will do just that.
This is precisely what most of us are worried about regarding EFPS. For the past few years every piece of kit that's been introduced has required
more 'head down time'.
Yes, I admit there are some ATCOs who resist change for the wrong reasons, but can you blame them sometimes? A few months ago I was showing a few visitors around from a well known ATC technology supplier. One of the engineers was asking me about the surface movement radar, which has labels for transponding a/c. I explained that it was a challenge to get new trainees who've not known anything else to look out the window, rather than just concentrate on the radar and strips. He said to me that surely that was the way forwarrd? That in a decade or so time it was his dream to build an airport ATC facility with no windows, and it would all be done on Mode S radar displays, and then could be co-located with Terminal Control.
Sometimes people get caught up in developing things just because they can.
