Having spent a fortune in filtering out weather from ATC radar displays to help us see the aircraft you now want us to put it back in??
Seriously though NATS (NERL) are looking at some form of weather radar but the problems are many. For example:
1) How does a controller 'know' if the weather displayed by radar is bad enough such that a plane could not fly through it?
2) What exactly might it be that would be displayed, might be anything from some heavy rain to huge CuNim with masses of thuinder cells.
3) Don't many large civil aircraft already carry and use weather radar?
4) How would you display it to a tactical controller? Hopefully not as an overlay thus obscuring the radar picture. As yet another separate display on a fairly cluttered workstation? Sounds like an ergonomic nightmare.
Early days on that study so far.
