I am given to understand that the primary reason turning off personal electronics in during takeoff/landing is so that passenger attention is directed towards crew instructions rather than distracted by gizmos, not because they actually significantly interfere with navigational systems. Also, from reading the linux-wireless mailing list, I am further given to understand that some rfkill switches physically turn the radios off and on, and some rfkill switches simple tell the operating system to toggle state. In the later case, it is possible for confusion to arise, becoming confused about whether you just turned something off or turned something on. -- Russell Senior, Secretary [email protected] _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
