I see what you’re saying and don’t argue it in concept, they very clearly define what a PED is…very specifically…using very specific definitions. There doesn’t seem to be any wiggle room of interpretation of what defines a Wireless Communication Device.
Again, most company policies cover that kind of thing that would get you fired, like even using your EFB tablet for taking pictures or video. But I don’t see how the FAA could go after certificate enforcement for using an electronic device under those regulations when the electronic device doesn’t fit the definition of a device that is specifically regulated.
