can a Cell Phone Signal crash a plane?
is it possible for a cell phone signal to interfer with a planes controls and there for crash the plane?
I would acctually have to say that yea it can because i was watching that mythbusters episode and the plane official said that it would be vertually impossible to test every model because a new one comes out like every day and they use diff technology so they would rather be safe than sorry.(i found the episode online a few minitus ago and this is what i found out.)thank you for all of your resposnes!
The odds are so slim for that happening, it's pretty much a no. However, there is a slim possibility if an aircraft were on an approach in bad weather and were to get erroneous instrument indications and fly off course very close to the ground.
Cell phones have the POTENTIAL to interfere with navigation/communication systems as they operate on a close frequency/wavelength. Phones transmitting near the 1700 Mhz range were found to have caused these incident on aircraft:
· Slaved Compass froze or overshot actual magnetic bearing
· Needles on instruments (engine/aircraft & nav) appeared unstable
· Digital VOR bearing display showed errors of 5 degrees
· VOR to/From indicator reading was reversed
. VOR & ILS course indicator errors with & without a failure flag
· Sensitivity of the localizer was reduced
· Background noise in the audio system
· False warnings of unsafe conditions such as smoke alarms in the baggage compartments
Here are some interesting links on the subject-

Personally, I have only experienced the background noise in my headset. Happens several times a week. (Especially, if I forget to turn off my own phone!!)
