The ADVANCED Quick Panel System and similar systems most likely work as advertised. However I do not think that there is much advantage in using these systems over wiring the aircraft yourself using Bob Nuckolls' diagrams and avionics manufactures wiring diagrams.
Most of the wiring in the Advanced Control Module is not controlled by the ACM CPU, all of the Avionics power is controlled by two separate PCB mounted avionics relays. If one of the Avionics relays were to fail you should still have one of the radios and EFIS screens.
I suspect that if Mich48041 spent a week on any Avionics Manufacturers (or Van's) phone support line he would have a radically different opinion.
Every week we are amazed at some of the wiring mistakes people (and experienced Avionics shops) make.
Advantages of the ACM
1. Easier to install
2. Easier to trouble shoot, something is wrong you can replace a cable in about 5 minutes.
3. No external ARINC module, flap controller, dimmer, or lighting controller module to wire.
5. High current loads for Nav Lights, Strobe Lights, Landing Lights, Pitot Heat, Fans and Autopilot do not go through the panel switches making them last longer.
6. PCB plug mounted panel switches eliminates all the panel switch wiring, plug in our ribbon cable and you are done.
7. UPGRADABILITY . Wiring a new GPS navigator will only take about 5 minutes. With the ACM module you can rewire from a GNS-430W to a GTN-650 in minutes and it will work the first time. With a hard wired panel that would be a large and expensive job. It took me over 8 hours to upgrade my RV-10 from a 430W to the GTN-650 and I am usually pretty fast at wiring.
