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

with a 747 i do the following:
- descending to FL240 at 0.75mach
- to FL180 at 0.65mach
- to FL120 at 300kts
- below 10000ft 240kts (250kts is the max speed)
- approach: established at 220kts
- flaps 5-10 degrees and speed established at 200kts
- flaps 20 degrees and speed established at 180kts
- turning on final: flaps 25 degrees (or full if you go to fast)
- short final: speed at 170kts
- during the flare your speed will be 160kts, the perfect landing speed for this baby

as for as for the 757 i don't know, i never fly it.

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.

i don't use unlimited fuel so i mostly land with less fuel and always at 150-160kts.

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.
