CDA's into LGW in the 757 are generally not a problem, 300-330kts in descent till around FL80, then VS-100 for a bit to slow back too 220kts....then FLCH down too about 1000-1500ft above platform, then its VS to keep you below the glide until you want to intercept. It gets tough when the director gives you a 45 degree cut for the LOC, you are already level with the glide, and you have 60kts tail/X wind component....and the grumpy cow won't give you a speed reduction
