This is your captain speaking ... or is it?

Re: storm in a teacup

isolation is only logical, not physical, on newer boeing models.

I'd prefer physical, but then again in a fly by wire world there is a certain amount of mootness.

Saves like 1989's United Airlines flight 232 are less likely to happen. Of course it was quite the long shot on the odds even back then...

Boeing has been using shared physical buses for a while now in newer 737s as well as 777, and 787s

"Novel or Unusual Design Features

The Boeing Models 737-700, -700C, -800, -900ER, -7, -8, and -9 series airplanes will incorporate the following novel or unusual design features: Digital systems architecture composed of several connected networks. This network architecture and network configuration may be used for or interfaced with a diverse set of functions, including:

Flight safety related control, communication, and navigation systems (aircraft control domain);

Operator business and administrative support (operator information domain); and

Passenger information and entertainment systems (passenger entertainment domain), and the capability to allow access to or by external network sources.

Discussion

The proposed architecture and network configuration of the Models 737-700, -700C, -800, -900ER, -7, -8, and -9 series airplanes may allow increased connectivity to and access from external network sources and operations and maintenance networks to the aircraft control domain and operator information domain. The airplane control domain and operator information domain perform functions required for the safe operation and maintenance of the airplane. Previously these domains had very limited connectivity with external network sources."

Re: @VinceH Optional

As Capt. Harkness once said "The 21 Century is when everything changes!"

"Firstly, no commercial airliner's avionics systems can be accessed from from either the entertainment system or in-flight Wi-Fi. Avionics systems are also never wireless, but always wired, and don't even use standard TCP/IP to communicate."

It's a fine line on some Boeing aircraft where entertainment and avionics are now allowed to share the same network infrastructure...
