Hi,
Turbine D
I am not a pilot but an engineer. I find the pitot discussion very interesting. There have been many suggestions on how to make this speed detection devise better as it appeared to be the first thing to fail in terms of proper operation in the AF447 flight
Are you sure the pitot tube failed ?
When I read the BEA report N°3 it's indicated that the plane was working as per design
The pitot tube worked also as per design
The plane and all parts of it were certified to work under certain limits
The accident of the AF447 show that the plane was put (or go .. make your choice) over the limits of certifications (and he stalled) .. as was the pitot tube (and he iced)
So the plane and the pitot tube never failed .. as .. when the pitot tube returned under the certification limits he worked fine again (nobody go outside the plane for fix it .. as he never failed)
Unfortunately the plane required some extra actions for return in the certification limits ... and those actions were no performed ...
Finally .. who failed ?
