About scanning, ... Maybe I'll have to try that next time I'm flying commercially. I love to listen to aircraft comms. In fact, I listen to so much radio communication that the few times I've flown commercially I feel practically blind not knowing what's going on.
Can anyone recommend a source for concise information on the regulations for electronics on commercial airlines? One that would explain what are the FCC rules, and what are the FAA rules?
I have always heard about the rules against radio equipment on board commercial aircraft. As a pilot, I'm fully aware that the captain has the final say about what happens on board his aircraft, as long as it complies with his airline's policies and the FAA regs. For any pilot like myself, the rules for Part 91 flying simply require that the pilot ensure that nothing interferes with the avionics. If the pilot verifies that it doesn't interfere, then it's ok. The two times I've flown commercially in the last year, they specify at altitude (10,000 I believe) that you can turn on laptops and other devices, but must keep off the cell phones and any devices which "transmit."
Which then brings in the cell phone issue. I've always been aware of FCC rules against using cell phones at altitude, supposedly because they would hit many cell sites and the network is not designed for that. I've always turned my cell phone off before takeoff, in my own plane, or in anyone else's.
Lately however, I've read that such logic doesn't necessarily apply. According to cell phone company technicians, 8,000 is the recognized cut off altitude. Above this, the cell phones simply won't work. Why? Most metal-covered airliners act as a shield. Only at a window can you start to eliminate that effect. Don't forget the cell phones put out less than one watt usually. Second, ever notice all the cell phone tower sites? Those antennas are highly directional, with each of those three parts covering about one-third of the 360 degrees around the site, AND, they are angled downward slightly. The signal from the sites is very weak above the site.
So, I was wondering what anybody thought about that? Have you ever tried using your cell phone at a higher altitude? I'm not sure I'd want to since illegal, but I suppose people have tried it.
