Aviation Today: Avionics

The day is coming when we'll need to do that , says Chuck Royalty , lead engineer for network systems with the Avionics Organization of the Boeing Commercial Airplanes Group.He sees it happening first in non-safety-related areas , to support new functions for maintenance and flight crews.

If there's ever a need on the flight controls or display side for 100 Mbits/s Ethernet , we'll have had the experience , Royalty adds.But current avionics display and flight-control applications don't need such high bandwidth , so my expectation would be , it's unlikely we'll see 100 Mbits/s Ethernet copper wiring go in unless there was some other reason..Such a reason might be cost savings.
But use of 100 Mbits/s Ethernet presents challenges , such as electromagnetic interference ( EMI ) , he says.Any time you put a high frequency on a wire , it radiates.Making it not radiate too much is the big problem with 100 Mbits/s..
The idea of a fixed , point-to-point bus is fading away , Royalty says.
The idea that we ought to be able to route data wherever it's needed without having to make major changes to the airplane is part of what's driving the [ Ethernet ] network..He foresees passenger cabin applications , such as video-on-demand ( VOD ) , or on the avionics side , the need for higher speed data transfer to the ground , driving the need for greater data transmission speed.
Boeing and other companies are working with ARINC on an airborne server specification and an aircraft data-network standard , Royalty says , adding that both specs would encompass Ethernet at 10 and 100 Mbits/s.

Chuck Royalty
Chuck was with us when we first started to work on the old-time-radio series First Hundred Years. Years later, in 2014, we had another run at the series-nine existing scripts out of 11 shows from 1949. He was willing to reprise his role in that show. He told me that he had difficulty choosing what profession to follow from college: acting or engineering. Chuck has been busy being an engineer with The Boeing Company. He can be seen in some stage productions in Bellevue, but a lot of his acting recently has been with ART.
