Boeing recommends  vref+5 during automated ILS approaches, yes that is 5 kts faster than VREF but not a whole lot. Airbus has  a similar system with VAPP and VLS.

Braking action is not greater during autoland, you still select autobrakes and they apply a constant brake pressure, regardless if the approach was auto or manual...however the braking distance may be a little bit longer, but that´s almost obsolete 

OK. I have tried it. Here are the results.

First I made an approach in the usual way I do. That is I turn off the autopilot and autothrottle before TOD point. Then I flew the STAR. Turned to final and hit approach. Ofcourse to catch the glideslope, I was below the glideslope a bit. What happens is that, the autopilot makes a descent at about 400-500 fpm when it is below the glideslope. So it takes some time to catch the glideslope. If you made an relatively short final then you may end up landing before rwy.

Then I made a second flight. This time I made everything same as before but activated altitude hold during the last turn. This way the plane kept going level until catching the glide slope. After catching the glideslope the altitude hold turned off automatically and the plane started its descent on the glide slope. And I made a perfect landing.

I guess, the point is to activate the altitude hold before the last turn.

so can you actually use aoutopilot to land??

thanks nexus. ill keep searching :
