Of course there is an attempt to link Habersheim with AF447 otherwise why mention it?

A very interesting question - will a UAS warning system actually be practical or developable? If so will it actually be feasible in service? We know that pitot tubes are being changed to the more reliable Goodrich models. However, it is probably time to replace the pitot tube with something new though what that could be is beyond me. I would recommend considerably more training and hands on experience for pilots and a thorough reorganisation of Air France's flight operations (which might even be underway as we speak) as I do believe that there is an airline specific cultural issue here.
