Sorry. I misunderstand. You are telling me I should tell the CAA they are wrong about this issue, and that such electronic devices don't affect anything on aircraft? Basically, I should tell them that their regulations are wrong, and they shouldn't ban use of these devices?

Which I indeed agree with. In their defence, it is an outdated regulation. At the time it was brought in, it was a sensible safety measure to take against unknown circumstances. And now proven to be unnecessary. As you can see, FCC and FAA are already reconsidering the issue. Time to update.

Would you care to explain?
