I get the 'buffer' offered by the stat met percentage, my point is that it doesn't really matter whether it is 85% or 82% or 75%, it is only a planning figure enhancing the chance of not having to change the plan on the day.
Getting an accurate diversion ETA is a bit late when you have already initiated it, especially as a back up to an AP position, however, I do acknowledge that in the emergency case it is a very useful tool.
As to where we go from here. Airbus DS have now delivered and certified and qualified system which the RAF will take into service. Once the simulator upgrades have been put in place and the aircraft SBs have been delivered, the team will begin to roll the system out to the RAF crews, developing operating procedures together to ensure that the system is utilised in the best possible way.
The problem with only dealing with the accompanied stage is a change in the way we do business, but there are ways of planning that deal with this issue and when the legs are accompanied from departure to landing, the problem goes away.
There are undoubtedly hurdles, and maybe if we had our time again we would have spent more time specifying the exact requirements of the system better, maybe even doing a bit of solutionising. It is disappointing that the system wasn't developed jointly with operational and technical specialists, but we now have to get the best out of the system we have.
I am sorry the an initial question about ATrS First Officers has turned into an MPS debate, but I think it is good to ensure that there is a balanced arguement out there. Can't let Beags have it all his own way ;-)
