MLS approaches available on all 4 runways at LHR. BA are installing MMRs (Multimode receiver) on the A320s & A321s.
The MLS approaches have been available for use since summer 08, but only to managers and trainers. Since 01 December it is open to all BA Airbus crews with the limitation of a 1000'AAL cloudbase.
The facilities are approved for autoland, but only currently CAT1 certified. Data from the approaches are being analysed for an eventual CAT3 approval. The critical path is the proving the reliablity of the ground equipement; a mean time between failures hasd to be proven before the CAA will allow CAT3 approaches.
Apparently if MLS had been available during that foggy period just before Christmas 2005 it would have paid for itself as there would be less cancellations and disruption for the Airbus fleet
