Abstract: A vehicle passenger information system, for example an inflight entertainment system, has a combination of improvements for reducing electromagnetic interference ("EMI") and electrostatic discharge ("ESD"). A microprocessor based system controller has a system controller chassis with a first conductive EMI shield layer, a low impedance aircraft chassis ground path directly electrically connected to the shield layer and to controller components. Additionally, a display unit has a chassis with a second conductive EMI shield layer enclosing a plurality of PCBs directly electrically connected to the shield layer. The display unit supports are grounded through a plurality of system connectors penetrating the display chassis and a low impedance display unit ground path directly electrically connects the two shield layers. A method of decreasing the EMI and ESD susceptibility of, and the levels of radiated EMI from, a vehicle entertainment system is also provided.
