What a nightmare scenario to be in. To look down and see no flight director commanding a left/right or up/down correction must be bloody scary, I think we can all agree on that. Especially with the runway and PAPIs out the window to confuse the already assaulted senses. It's all very well sitting in front of a laptop screen in a warm lounge and spouting out stuff about setting appropriate pitch and power and keeping the TDZ stationary in the windscreen but you're missing the point - THE FLIGHT DIRECTOR had failed. Manually landing an airliner is next to impossible with the failures they got. Bravo I say.
P.S. Agreed, the check pilot was a numpty.
