Here we go again, if the avionics are this sensitive then it isn't safe to fly. this is the old case of use, and pay for our stuff or use nothing at all. |

Seriously, what's the issue with interference in planes? |

Absolutely correct I know ham radio operators that bounce signals off of high flying jet aircraft undersides increasing the range of a 2 meter, and 440 mhz transmission by many hundreds of miles. This has been going on for decades and no harm has ever been done.

Yeah it would have to be a lot of power with a highly directional antenna, that is tracking at 600 mph. They would also have to cover certain frequencies. They could go manual then to avoid a crash. I don't think it would affect GPS mounted on the top of the plane or even a compass, altimeter, etc. Good luck with that. |

Also there is a limit on how much power they can transmit. |

This actually happened on a flight I was on. Capt. asked if anyone had a cellphone on or sat equiptment. 2 minutes latter he asked again and said it was screwing up the nav. system and they had to use a backup system. Then a guy jumped up from his seat and turned off a sat. phone he had. Capt. then got back on the speaker and said thanks interference was gone. This was a sat. phone though.
It was on a American airlines flying from Miami to the Cayman islands. |

I think you are right on the money Transamaster. These planes a built to withstand a direct lightning hit! It's probably based on a business decision. Having said that, I think being stuck close to someone yapping for 3 hours is cause for a good Homer/Bart type of strangling! |

Remember that many planes in service today are over 25 years old. Cell phones, PC's, microwaves and such weren't even thought of back then, so how could the avionics engineers even anticipate the possibility.
Besides, people are downright rude when they talk on cell phones in close areas. I don't give a rats ass about about your delayed meeting and ideas for a new proposal. There's a time and place for everything, save it for then.
If I could get some peoples phone, away from them, it would end up in the little blue ocean in the tiny room at the back of the plane! Nobody NEEDS to be that in-touch or accessible. |

| Boy you are sure right about the irritation there was some lady in line at the supermarket and her cell phone range she would not get out of the way but would get her stuff checked out so we cooled our heals which this witch had her conversation with whom ever.
I can understand a sat-phone messing with nav systems the frequencies they operate on are in the same range as the GPS receivers on a plane.

I think you should only be able to use the cellphone maybe 10 minutes a day. I would hate to be on a flight with some A**hole talking (probably yelling) for the whole flight. My favorite use to be housewives in their sweat pants at a supermarket talking away on the cellphone. What the H*ll could be that important. Think they thought they were cool. LOL. |
