Hello!
I am in the planning phase of installing a complete Dynon system to replace my antiquated TruTrak EFIS. One of the things I opted for was the heated Pitot with AOA.
Please allow me a moment to form the context of an electrical question regarding the grounding.
Page 3-2 of the referenced installation documentation [1] states:
Do not connect the Black (Ground) wire to the airframe as a Ground connection.Doing so will introduce high currents (10A) into the airframe. This can introduce asignificant voltage drop, and potentially cause engine instrumentation, avionics,and audio system electrical problems
A few pages later (3-4) Figure 7 shows the ground terminating on the aircraft ground.
My question:
Are they saying that I should home-run the ground wire all the way back to my common ground block behind my panel? If not, then please advise.
FWIW: The current heated Pitot is grounded on the airframe to a wing rib.

Thank you in advance!
