The AFS angle of attack system includes a sensor/processor box that takes up quite a bit of real estate. It also has a big connector and a set of pneumatic ports that are on opposite ends of the box, which doesn't help. At least it doesn't weigh much.
I had to take the cover off the box to see what was inside. Kind of an old-looking board design. Oh well, if it isn't broke, et cetera. Dig how they used really long machine screws as cheap heatsinks for their power transistors.
To mount the box, I bent up this bracket out of 0.025" alclad:
Short screws and Loctite attach the box to the bracket:
The two leftmost mounting screws on the bus 1 fuseblock go into the nutplates on the AOA box mounting bracket (visible above).
Here it is attached to the forward side of the subpanel. This is pretty much the only place I could find to mount it. If it ever has to come out for service, it will be easy to remove those two screws and drop the whole thing out from underneath the panel.
