I love debating this stuff. Here’s my take on raw data flying (tTrolls welcome). I think the FD should always be used for the takeoff because it’s just a professional decision that shows sound judgment. Then, precluding congested airspace or high workload, I say once the flaps are up and if a pilot wants to practice their scan, have at it. Turn that bad boy off and hone that scan. It’s all good. What’s the big deal?
