Re: Nice Scam by Cingular
Umm, maybe if it was sitting right next to the radio. Every kind of interference you described only has an effect if the phone is within a few inches of the device in question. Also the devices you mentioned are not designed (nor are they required) to shield themselves from such interference. Aircraft radios on the other hand have to be designed to reject any spurious interference from other RF transmitters in the area by using notch and bandpass filters that reject any out of band interference. Both the FCC and FAA have very tight regulations and testing that these radios and intercoms must pass before they will be approved for use in an airplane. In fact, there has been no documented case of a cell phone actually interfering with the radio or avionics in any airplane. They were banned over concerns of potential interference nearly 14 years ago, when most phones operated with a far higher power output than they do today.
I bring up handheld GPS devices only because many airlines have banned their use inside airliners for the same non-existant interference issue. If that were the case then there would be countless general aviation aircraft having regular avionics malfunctions from pilots using them. |
