Correct; but as was touched on in another topic, this glance is often only to see of the FD is centred, which with A/P in CMD it will be. Let's remove the FD when A/P is in CMD. This will force a better scan
I don't know if they still do, but I believe United Airlines used to do just that. My understanding was that when you selected autoland on the 767/757 fleet, the flight director would disappear.
Of course, on the 727, we never engaged the FD unless we were actually flying an instrument approach...the rest of the time it was just pitch and power. Therein, perhaps, lies the problem...
