80186 architectures
PBL, You are mistaken about the 8086 architecture. The 8086 is a true 16 bit architecture with full 16 bit data paths. it was the first member of the Intel family of processors to come out. I think you are thinking about the 8088, a chip that came out shortly after the 8086 as a lower cost alternative. The 8088 is the one with the 8 bit data path, and is incidently the chip around which the first IBM PC's were built.
The 80186 is a chip that has the identical core processor architecture as the 8086. The 80186 variant added many of the typical peripherals used in a system design to the processor chip. These included items like an interrupt controller, etc.
As far as EMC issues are concerned, all aircraft systems were tested for immunity against EMC long before 10 years ago. The FAA's certification procedures required EMC checks as specifed in thier RTCA documents long before that.
