Yeah the electronic equipment policies are the antithesis of any evidence based practice which the rest of us are expected to implement and follow to keep our jobs. Whilst airborne, while the engines are running, when the doors are shut (and how do you know that if you’re not beside one), during take off and landing (define that), while the seat belt sign is on – does that mean you have to stop using them during cruise turbulence? – etc etc. Some announcements on the same airline are even inconsistent with or contradictory to one another. Then there are airports – at some you are supposed to turn off mobiles at the gate especially if a walk-out to the aircraft, but you can then use them again on board until the engines start or whatever – reverse on disembarking.
One for Mark’s psychiatric expertise to hopefully provide an explanation. Certainly doesn’t stand up to any scientific one.
