I'm surprised no one has mentioned it yet but your best source of realtime information on FMC equipped aircraft during landing is Prog page 2 (Boeing types). I know there is a similar prompt on Airbus aircraft, just don't know what it's called. It gives realtime wind direction/speed, crosswind speed in knots and either L or R direction, and vertical track error in feet from whatever type approach has been selected. I always have one of the FMC's on that page during landing. It keeps me legal and keeps me from getting surprised. Having said that, even with all the automation/computers available to us, at the end of the day it still boils down to being able to do "Pilot" stuff.
