Air Conditioner and ADAHRS and Remote Compass

[lynnb]

So I've tentatively decided I want to install an Airflow systems air conditioner in my 10. I've also tentatively decided I want a Dynon/AFS panel. So I'm wondering about the mounting of the ADAHRS units in the tail, and any electronic interference from the A/C components. Does anyone have this combination and had any issues? How far back did you have to place the ADAHRS and is it still reasonably accessible?

My other thought is to install the remote compass in the wing tip, but that would be more than 6' from the center of the plane, would this work or is that a bad idea? Does it matter which wing it is installed in?

Thanks in advance.

I've done 2 x 10's with the aircon & mounted the ADAHRS units on the 2nd bulkhead (close to top of fuselage) aft of the luggage bay panel, works well.

Lynn:

The <=6' Left or Right of CG requirement is only for the SV-ADAHRS-200/201. Thus the SV-MAG-236 can be installed in a wingtip. It would not matter which wing it's installed in.

Just a note that if you decide to add the remote compass, it doesn't have a restriction on distance from the CG like the ADAHRS does. You do want it away from ferrous metal and power though, of couse (ie magnetic interference). The distance restriction is for the attitude sensors (accelerometers/gyros), which are only in the ADAHRS. So you could then, for example, put the ADAHRS somewhere near the CG of the aircraft, or behind the panel, and then put the optional remote magnetometer in a wingtip of elsewhere.

Or, as Jake suggests, the 2nd bulkhead might be a good enough all-around option for the ADAHRS if it's far enough away from the AC unit. The ADAHRS nominally provides heading when the optional remote magnetometer isn't installed.

Thanks for all the great information!
