Well this is good but it seems to me there ought to be a "pilot optimized" GPS in commercial airliners particularly you can program with the runway number when you get it really quickly and it tells you if you're on the right path . . . won't help doing a corkscrew into LHR or any weird hold patterns like that but in straight in approaches . . .
I am probably over simplifying but it seems to me there should be a tech assist possible here.
