Re: Shouldn't be a law
said by expert007:All problems were from a bad cable connection. So normally, electronics will not have any effect. And in a 6 week study no one reported any problems. That's a pretty long time to see not one issue.
Interestingly enough, during the entire six weeks of the study, conducted at Heathrow, Frankfurt, and Cincinnati, no compass malfunctions were recorded. There were, however, in the over 300 tests performed more than 50 attributable malfunctions demonstrated.
All of the malfunctions were correctable by reterminating the shielding on the affected coax or simply reseating what was probably an improperly installed connector.
And they were testing electronic devices and not cellphones that gave off cell signals. So this doesn't even apply to cellphones.
And they just say a laptop caused interference. What kind of laptop? Did other brands cause the same thing? What kind of signal was given off? How strong was the signal? etc. So many unasked questions.
Considering lots of electronic devices are used on planes every day and many cellphones are probably left on in people's pockets, it is supported by the data that planes just are not effect enough by electronic devices to worry about it.
You can throw out all the studies you want, but until a story makes the news where an electronic device or a cellphone caused a problem, there is no point in pretending the world will end if you make a call while in flight.
First of all, you misinterpreted what he said. Reterminating the shielding or reseating the connector solved the issue. Since you're obviously not involved in the day to day maintenance of aircraft, you fail to understand that that is NOT a permanent fix, ergo that shielding issue is a potential ongoing problem.
Secondly, you're cherry picking words. What he said was that "no COMPASS malfunctions were recorded". There were however more than 50 attributable malfunctions NOT related to the compass. FYI, the compass is ONE of MANY systems.
I'm glad that aircraft design engineers don't make airplanes using your logic..."It's all good as long as I don't see that anyone died on CNN"
BTW, no one (including me) is insinuating that the world will end if you make a call while in flight. What we try to avoid in this aviation industry is avoid creating the potential for the *perfect storm* of events that could create a catastrophe. Not that you're going to listen to what I'm saying but WE look at what could potentially occur, such as "passenger makes cell phone call at critical phase of flight/shielding on flight management computer is compromised due to improper modification/flight crew, who is overtired misinterprets conflicting data on captains & F/O's source/windshear goes unreported, etc etc". That's reality, again, I'm not making this up, but please, don't let the facts get in the way of your opinions.
You are just spreading FUD. Since people use electronic devices on probably every flight of the thousands going on at any one time and none of them are having problems significant enough to force the industry to ban electronics, your claims are 100% baseless. Cell phones were originally banned because they feared cell phones switching towers really fast would cause problems. And electronics were never banned.
Well, you haven't provided ANY facts, ANY evidence and nothing but belligerence, whereas the other guy sounds like he's actually involved in the day-to-day workings of the airline industry. You're a backseat expert - he clearly knows.
You need to take a long look at yourself - admit you're wrong for fuck sake.
