Well I'm not a big fan of the 511 we use, but we dont really have the problems discussed here. Ok its not a heavily processed radar so may not be relevant to this discussion, but it does show weather rather nicely if the background video is selected.
Thus by toggling between having background video on and off you can display where the nasty stuff is; I tend to check with the crews that we are talking about the same bit of wx then it is very possible to at least get an idea of where the crew are likely to want to go.
I should add that without the background video on ie normal ops, only very heavy stuff will be shown so the wx filters do work very well.
Perhaps other sytems have become too processed?? Discuss...
