D'oh, very simple, but forgotten how! Isnt it:
G/S(ft per min)*(Glide slope in degrees/60)=Rate of Descent
I keep gettin 6201 ft/min ROD on a 6.8deg slope, which seems unusaully high...

For the required rate of descent multiply the descent angle by the NM/minute times 100.
Taking your example...
540kt = 9NM/min
12° x 900 = 10800'/min.
But... who would fly a 12° angle

Oh, sorry for that! You are absolutely right - it is gradient, not a slope...
In that case, to find the rate required, multiply the gradient by the GS (or rather TAS).
12% x 540 = 6480'/min.

Well your method seems a lot simpler than mine, might adopt that for the future...
