John -

I have not seen nor heard of anyone installing a second pitot tube;  
although we did install a second static port and systen for the Tru Trak  
AP. If I had to do it over again, it is just as easy to install the second  
pitot tube. Aside from the engine itself, this is the most glaring single  
point failure and the cheaper system to install a duplicate - assuming, of  
course, that one has dual batteries and dual alternators (which we do have  
on our ES) :-))

Go for it.

Cheers,

John Schroeder
