Your 787 controlled from seat 34G?

Common Core System

I have been working with software development for more than 35 years. I have been working as programmer, system designer and in different management positions within software development.

In addition to the obvious problems connected with the common network in the 787 I am also concerned about the CCS or Common Core System in the CCR Common Computing Resource. In it there will be an operating system ( Vx Works 653) managing the different applications running. Those applications will as I understand it be everything from passengers running games or surfing the internet to critical flight systems. It has happened in the past and it will happen again that some bug for instance in an application will crash the operating system. That might very well make the whole thing go down.

Based on my experience I would say that there is no such thing as a complex software system without bugs in it. There are always bugs and it may take years before one suddenly surfaces and brings the system down.

I don’t want the pilots of my flight to a sunny beach sitting in the cockpit trying to restart the CCS.
