Greetings,

 

I will have an AOA in my Legacy.  <= /p>

 

That said, I am concerned that if for some reason my pitot = tube gets blocked by something like an insect, bird, or other debris, my = airspeed indicator will probably be giving me an erroneous reading.  = <= /p>

 

Would not this error also be reflected in the = AOA?<= /p>

 

Therefore, would it not be a good idea to have the AOA on = its own pitot source?  And could one tie both pitot tube together so that = if one was blocked, the other would continue to provide pitot = pressure?<= /p>

 

Thank you in advance for your input.<= /p>
