Well you have been referred to the FAA Regs and the Airline policies and
ignored them. http://www.fordyce.org/scanning/scan.../scan_fly.html http://www.airweb.faa.gov/Regulatory...e?OpenFrameSet Section 91.21 -------------------------------------------- So here is another URL we hope you read about GPS http://gpsinformation.net/airgps/gpsrfi.htm Just a snip: There are documented cases of AM/FM radios causing interference with Avionic systems and as a result, AM/FM radio receivers are generally prohibited. You will be happy to learn of this quote; "By design, (or happy accident), the "spurs" generated by a GPS generally fall outside the communications frequencies used by Aircraft and so have not been a problem even though a few "spurs" exist. But SOME airlines do not permit the use of GPS receivers. Why is that if they are "safe"?" You will be unhappy with the answers. Hope you go to the URL for the answers Here is one: If a GPS is safe, why can't I use it on an airplane anyway, even if the pilot says NO? Answer: This would be a) unwise, b) illegal and c) dangerous. Never presume that you have more authority than the Captain of a ship! He is responsible for the lives of his passengers and likely has knowledge and experience about his aircraft and/or equipment and/or this particular flight that no one else has.. The use of a GPS by a passenger is NOT worth a confrontation and a possible visitation from the police or FBI when you land.. READ THE LAST SENTENCE AGAIN Be safe, obey the law, stop guessing -- get educated and read these URL's -- RF Gotta Go SomeWhere "Some Guy" wrote in message ... What a load of horse ****. You guys are acting as if the engines and flight control surfaces of an aircraft are intimately tied to the plane's radio receiver, and the slightest odd or out-of-place signal that it receives is enough to send any plane into a tail spin. All this while the air travel industry is considering allowing passengers to use their own cell phones WHILE THE PLANES ARE IN FLIGHT by adding cell-phone relay stations to the planes and allowing any such calls to be completed via satellite. So I guess the feeble radiation by my FM radio (powered by 2 AAA batteries) is enough to cause a plane to dive into the ocean, but the guy next to me putting out 3 watts of near-microwave energy is totally safe. What about my hand-held GPS unit? Any chance me using it (during all phases of a flight, which I do routinely) will result in a one-way ticket to kingdom come? Getting back to the original question (poor to non-existant AM reception), I understand the idea of aperature and long wavelenths of AM radio and the size of airplane windows - but what about the effect of ALL the windows on a plane? Don't they create a much larger effective apperature when you consider all of them? And since the plane isin't grounded, isin't the exterior shell of a plane essentially transparent to all RF (ie it's just a re-radiator) because it's not at ground potential? |
