In according to Airbus we can't start to descend until the point where we can observe rw thr or some lights and so on,therefore base has to be performed without descending,just flaps full and try to find rw,when rw is identified-you have to start descending,just performing visual pattern,GS(+-10 kts per 0.1 gl/sl)/2 is Your v/s,d*3 is Your position on the gl/sl
I try to do it this way
Any other tips would be greatly appreciated
safe flights
