Re: [PLUG] Kingfisher - linux
Thirdly, did they reboot it mid-air or on ground? The topic is around in-flight entertainment. So it may be OK, even if rebooted mid-air. -DP -- On the internet, no one knows you are a penguin Check my blog at http://desipenguin.blogspot.com/ -- __ Pune GNU/Linux Users Group Mailing List: (plug-mail@plug.org.in) List Information: http://plug.org.in/cgi-bin/mailman/listinfo/plug-mail Send 'help' to [EMAIL PROTECTED] for mailing instructions.

True... but considering the very strict norms followed by the airline industry I am just curious to know. I do not think strict norms apply to inflight entertainment. The PA system yes but not entertainment. Most times that I have flown on international routes, I have noticed that the in flight entertainment (when available) do not work on all stations (my bad luck 100%).

Most of the content is delivered directly from some tv satellite As for DO 178B certification, a software can be certified as no effect or minor. In such case rebooting of the system mid air is absolutely allowed as long as the software is accompanied with a problem management tool. regards VK -- The hidden harmony is better than the obvious!! -- __ Pune GNU/Linux Users Group Mailing List: (plug-mail@plug.org.in) List Information: http://plug.org.in/cgi-bin/mailman/listinfo/plug-mail Send 'help' to [EMAIL PROTECTED] for mailing instructions.

So is Virgin Atlantic from what I recall they developed the app. in house. Unfortunately, don't have the link to the article. Biz are realizing the cost of software. For a similar app. on Windows CE (or whatever it is called now), the airline would have to pay lic. per passenger seat plus for the server. The Linux solution: development cost (once), software deployment cost (lic.) to all their aircrafts close to $0. -- Arun Khan -- __ Pune GNU/Linux Users Group Mailing List: (plug-mail@plug.org.in) List Information: http://plug.org.in/cgi-bin/mailman/listinfo/plug-mail Send 'help' to [EMAIL PROTECTED] for mailing instructions.

On my last flight home, they had some problem due to which screens in some parts of the aircraft did not work, forcing them to reboot the system a couple of times.
