Nothing wrong with a bit of raw data for practice. However I think it should be the exception rather than the rule. I don't know how many times I have corrected pilots for letting their scan rate lapse (particularly in a bit of turbulence on departure). They concentrate so hard on the ADI/PFD and forget the rest. If they had their F/D on, they would have received good info to turn left/right to maintain the correct track etc. Accuracy is very important at many airports.
I know some guys have followed their F/D into the ground, but it is usually pretty rare. There are probably grounds for a good argument on both sides, however if F/D's were not an improvement on safety, they would not have been designed in the first place. If they are fitted (as they are on nearly all modern jet transport a/c), they should be used!
