But it's still as I said: "new and currently non-existing equipment", and the next aircraft going down will just happen to not yet have the equipment installed....
Which in itself is absolutely no excuse not to start working on a proper solution. I find it hard to accept that with the technology available today it seems nearly impossible to locate an airliner that went down into the ocean.
I also do not like the argument that a solution is not needed because "it does not happen very often". This accident could be a landmark accident in relation to the use of pitot tubes in high altitude adverse weather. Also: think about what happened to the BA 777 at Heathrow. Does the fact that the apparant ice accumulation in the oil-fuel heat exchanger only brought down one airliner make it any less important?
