Seriously though, you still have to monitor that the FD is giving correct information and that requires an instrument scan. Some older types can get you into serious trouble if you blindly follow the FD
Agree 100%, but is that really how it's being taught? The last time I was in the sim, the trainee was new to the type, and was having difficulty with SE ILS approaches. The instructor kept pushing the guy to follow the FD, even though doing so made the job harder. I use the FD bars as guidance, however it seems that many instructors teach the FD as a command.
Heaven forbid you should turn off the FD when cleared for an approach...
