Brief Description: Prewire and plumb for 2nd ADAHRS unit
The ADAHRS installation is set up to be a stack of two units. While the wing skins are off I wanted to pre-fabricate the installation so that if I decide to add a secound unit I can do it one-handed through the single access hole in the lower wing skin. The D-sub connector and 2nd Outside Air temperture sense wires are attached to a dummy ADAHRS unit that sits on the primary unit. The static, pitot and AOL lines are pre-fabricated as shown. The initial flying configuration will have U-joints instead of the Tee's in the lines. I should be able to one handed, remove the ADAHRS stack, change the U's to Tees, replace the dummy AHARS unit with the back-up unit, plug in the D-sub and OAT plugs, reinstall the stack plug in the old lower and new upper pitot, static and AOA lines. Plug and Play.
