Times usedl
I can't give you the number of times but whenever the weather is below CatI. It's not just CatIII but also includes Cat II. All the QANTAS jet fleet is CatII or CatIII. So on those days when conditions are less than 200ft / 800m it can be used. The RVR transmissometers also allow CatI down to 550 RVR. Takeoff is also available down to 125m RVR RWY 27 and 100m RWY 16 providing the operator is approved. This opens departures to Jetstar and Virgin who will eventually move to CatII / III. So eventually ML wil have diversions and missed approaches due weather almost a thing of the past. There are some limitations around RVR transmissometers certification and rain. The Advanced Surface Movement Guidance and Control System also speeds up surface traffic handling during LVP.
