Whats the flight director like on the metro?
The sperry ones we have are pretty good but down low the in built lag requires you to look through to keep the sensative localiser scale bang in the middle.
And I agree with A pumps it does require a wee bit of experence to suppress the urge to make the picture fit with inapproaprate control inputs when you get that intial "lights in sight" the max 5 degs bank is there for a reason.
Again we come back to a tight stabilised approach well within the tolerances afforded leads to a safe landing.
For those that don't do manual ILS's or NPA every day it is quite normal for competent crew to fly it so exactly that if you just saw the instrument you wouldn't be able to tell if there was a AP driving it or it was hand flown. For an experenced eye you would be able to tell because you would see the ballooning when lift flap was selected with the AP machine where as the manual the pilot would have spun in a couple of turns on the trim wheel as the flap was running so you wouldn't see the balloon.
Unfortuantely seven the group feeling amongst my mates is that you are correct. There wasn't much point at the time running with your theory because the CAT II pish was getting rolled out.
Anyway for those of us that do this sort of stuff day in day out fly safe, its only a job at the end of the day. No point paying the ultimate price to prove that you were right and it wasn't safe to go.
