Hi all, as previously posted , lately I have been landing well short of the runway whilst on ILS.

I just wanted to ask, does Throttle Speed need to be adjusted to keep up with the ILS, I mean, maybe I am reducing speed to much, and thats why I am landing short of the runway.

I am flying most of the time either 757 or 747's.
What is the ideal landing speed for these 2 aircraft types, and at what distance should I have this speed set?

Thanks again...Tomcat61

For all aircraft's approach speeds, it all depends on your gross weight to determine anything.

If you're flying unlimited fuel (as most newbies do (or just the aviation enthusiast taking it easy)), THEN the flare speed in the 747-400 is around 160kts.  

In the 744, with fuel at around 60,000 lbs or so, approach speed is around 160kts, flare is about 150, or less in some cases..  If you try to flare and you're too fast, you won't flare at all, instead you'll just start climbing.  

Reason: 744's are designed for long hauls.

Just try it yourself; set all fuel tanks to 30%, and try taking off.  You will be able to take off at about 85% N1, in just about the same distance if you had the tanks set to 100%.  Fuel weighs a lot, surprisingly...

Yeah, check to see how much fuel you're landing with, if it's too much autopilot might be bringing you down short of the runway, or if you keep reducing power while you have the APR button engaged I notice that any decrease in speed and the autopilot lets the glideslope slipe a bit so it's best to be set on Vref before engaging APR. Hope this helps.
