Most certainly is .... chatting about "onboard rules" in the pub one night with pal of mine who flies Dash 8's for a living,- he mentioned that that earlier that day they had just vacated the runway at Gatwick when he was unable to hear what the ground controller was telling him - due to that strange "dit dit dit" noise in his head phones caused by probably more than one of the passengers in the cabin switching their mobiles on.
Have heard the same noise over the headset when sitting on the flight deck of an Airbus as we taxied to stand. If it had hapenned as the flight crew were making a radio call it would most definitely have ineterefrred with it.
