Is it OK to have two seperate pitot tubes come together at a simple "y" junction, and feed the same instrument?
Here's why I'm wondering... Dynon still doesn't have a heated pitot/AOA probe (maybe never will). Their AOA probe is part of their pitot tube, it works on the difference between the pressure in the two holes. If the Dynon pitot freezes up, you not only lose airspeed indication, but attitude information as well, which could be really bad (this info from a Dynon employee who posted on a Dynon forum). So... could I just put a splitter off the pitot input to the Dynon, and have a second heated pitot feeding it as well?
My (rudimentary) understanding is that this should be OK, because the air pressure shouldn't depend on how many ports are there (nor on the diameter of the opening in the pitot tube)... but I'm wondering if there are other effects I'm not aware of?
