So dominating the news over the last few days has been the missing Malaysian 777 airliner. I just happened upon a blog post buy some guy who is apparently well known (it made it onto Digg as the top story for the last few hours, if that means anything). In it, he argues that the communications used by airlines is outdated.
Some quotes...
"all they have to connect with ground is old style radios"... "radios that sound awful"... "radios are not safe"... "radio which has poor sound quality"... "primitive". I could go on.
His post is kind of rambling, but he argues that all pilots need sat phones and data recorders and ipads connected to the internet and a bunch of other new stuff. When the sh*t hits the fan in a cockpit, I'm not sure what all of this additional technology adds other than more work load. When Swissair 111 slowly burned in the sky, incapacitating one pilot and taking away all of the cockpit electronics, it surely wouldn't have helped. There is nothing simpler and more reliable to build than a radio with a PTT switch.
You can read his argument here:
