This is an interesting hodgepodge page. The first two pictures show some noise preventive measures. With antennas and wires and lots of electronics you can get a lot of RF noise. This can cause terrible static in the comm. system as well as malfunctions of some devices. These ferrite beads do work and there are scientific principles behind there use but I hate them and consider them just a step up from voodoo. None the less, I held my nose while installing them.
The third picture is of the replaced voltage monitoring hardware – wired correctly this time. The last picture is of the cockpit in red light, night vision mode. This is full bright and it can be dimmed way down.
