Ridiculous Pitot redundancy implemented

Quote:

These pieces of hardware are built under tight tolerances, live the same life in the same environment and pitots 2 and 3 occupy exactly symmetric positions on the fuselage

Considering Airbus SAS didn´t have supply of "hotter" Pitot´s a much safer approach would be to put several Pitot´s in selected locations of the a/c and feeding a reliable "voting scheme" subsystem.

The "redundancy" used in this design may be is "amplifying problems".
