6.10 ACU Installation
The ACU has no user interface, and therefore can be remote mounted. The optimum
mounting location is an area that minimizes wire runs to interfacing equipment. This typically
means near the autopilot computer if installed.
When mounting the ACU find a location in the aircraft of known load carrying capabilities such
as:
• Existing Avionics Shelf
• Baggage compartment
• Radio Rack
• Cockpit Floor
