Stilton......It doesn't matter what Aircraft you're flying, down the GS you fly the correct attitude, thrust and therefore speed for your type adjusting as conditions require to maintain the GS. Below 150' to 200' feet you primarily look at the aiming point ( still checking pitch att is correct on the ADI and IAS ) and only look up to the far end of the runway as the flare maneuver starts around 30' or so.
In most Jets the actual flare action is only about 2 deg, you don't need to look at the ADI to work out how much that is, practice will tell you by looking out the window. The Flare isn't an IFR maneuver!.
The biggest mistake newbies make is forgetting the aim point and letting the nose rise up well before 30' ( they see the runway rushing up and flare too early ) and thus they float down the runway and land long, Autothrust doesn't help in this regard either. You must keep the aiming point in the same spot in the window until the flare. The only exception would be if you'd cocked up the approach profile and were either high or low, then you would have to modify the attitude/aiming point to compensate and in extreme cases go around!!
It's very important the new Pilots are taught exactly where to look and when.
The older experienced Pilots just do it!!
