All of the internal workings of our products use the internal wiring for 28V DC ground, as well as for chassis ground.

Most of our products have metal casings which, when installed, provide a common potential between product and plane.

The few products that are solely encased in plastic (FD900X3 or FD900X5 Wireless Transmitters, etc.) would just use the 28V DC ground as the chassis ground.
