I'm afraid you've misunderstood.
Firstly, the effect of a Faraday cage isn't symmetrical - i.e. it protects things inside it from external electric fields, but a charge *inside* it will still generate a field outside it.
Secondly - the Faraday cage effect, which applies primarily to electrostatic fields, is not the same thing as electromagnetic shielding. Faraday cages, by their very nature, can have an RF shielding effect, but that's not really what is generally meant by the Faraday cage effect.
However - all this is largely irrelevant to the "turn off electronic devices" discussion. Faraday cage immunity to electric fields outside the aircraft is not related to immunity to RF radiation originating inside the aircraft.
