It can't do harm to the aircraft in any mannner. So what's the big deal? Steve While it is not a transmitter by design it still transmitts weak signals. There are various oscillators in the scanners that can act as very low power transmitters without antennas. The range may be only 100 yards but that can be enough to cause problems with the radios and other electronic gear in the plane. Just imagine the scanner outputs a stray signal on the navagation receiver or it blocks a transmissoin from the tower at a critical point. Not likely that it can hapen but they want to cover all the bases. Yet they will allow you to use a Laptop, portable DVD, Gameboy, electric shaver, etc. All of these will put out as much if not more RF interference than a scanner. If the airplane's navigation system is so suceptible to RF interference, what's stopping terrorists from taking advantage of this by using a scanner secretly, say in their pocket with an earpiece? Or, does the scanner have to be seen by the flight crew for it to have any ill effects? |

Or, does the scanner have to be seen by the flight crew for it to have any ill effects? I don't hear computers, DVDs, Gameboys, and shavers over a block and a half away in my car on VHF and UHF, but I can show you areas where I CAN hear the LO of a scanner 'sweeping by' when I drive through at that distance. It's not ALL scanners. Some are worse than others. Heck, I've gotten permission to use my 2M ht in flight, as long as I promised not to transmit, and advise the captain when I turned it on AND when I turned it off. (I assume he was actually going to look at things to see if he could detect any issues.) Stop whining, keep the scanner shut off when you fly, unless you are in a private place and the pilot in command says it's ok. |
