How should the Pitot/Static system be plumbed if using AOA?

[dratte]

Since the Pitot/Static/AOA unit is not certified, it is required to continue to use the original P/S system in the aircraft and mount the AOA probe separately.

20.7.2 States that the original certified P/S system connects to the D10.
I'm presuming that the new AOA/P/S probe connects to the ADAHRS-200 and everything else?

I checking for clarification as 20.7.2 also mentions "T" fittings to other things, so I'm not clear on what was intended there.

I'm also somewhat disappointed that the certified AOA masthead does not contain heaters, but I get the complexities and electrical impact of adding another 10A heater next to the one that is already there as well as an STC not being able to supersede a TC to replace the original P/S mast.

Is there anything else I might have missed?

Thanks,

In a certified installation, you'd only use the AOA port on the probe. An excerpt from the latest manual as of this post: "The Dynon Avionics AoA sensor is not certified for use as a Pitot sensor" (section 20-1)

The T fittings would tee things off to any other devices that need pitot/static (like the ADAHRS, the EFIS-D10A, and any other non-Dynon devices that need pitot or static)
