Does filming your takeoff and landing really interfere with the operation of an airliner?

4. Does it? Usually not. Can it? Theoretically, with very low probability

All digital devices produce radio frequency electronic noise.

Digital electronics are capable of picking up that noise and generating an error.

Will YOUR electronic device crash the plane? Probably not.

What probability are you willing to accept? If you said something like "one in a million" then you would also accept several aircraft malfunctions per year, because millions of people fly.

It's a very low statistical risk which is not definitely calculable across all electronic devices (whether or not functioning properly) and all aircraft electronic systems. So, for that reason, they ask that you not use those things during takeoff and landing, when small errors may matter.

As a practical matter, the risk is negligible.
