Uplinker:
What ? NOOOOOOOOOOOOO!! For goodness sake scan the instruments people !! Are you pilots or amoebas?
And if you need an iphone app to work out altitude versus distance; Go back to flight school. Seriously. This is really important.
Be careful what you are promoting, Uplinker. It is comments like this that have new f/os playing with the FMC at 200' on final approach (visual or otherwise).
This was a visual approach. The big picture is outside, and not in the cockpit. At most you need a quick glance at the airspeed every 10 seconds or so, that's all. The NFP should be making a call out of 'on profile' or not. And we all trust the NFP, don't we?
Remember power and attitude? A stable aircraft on profile will remain, well, stable and on profile. And if you cannot feel an engine rollback or a windshear change through the seat of your pants, well perhaps you are one of those who should have gone into the bicycle courier business.
