CD players etc
There's been much discussion about the risks - theoretical and practical - posed by mobile phones aboard aircraft. Can anyone tell me about the widespread prohibition on the use of personal CD/Minidisc players and laptop pcs during t/o and landing?
I'm intrigued to know if this is adopted because of a known interference potential, or does it have more to do with thoughts of pax not hearing emergency PA calls and/or having evac impeded by clutter?
