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

9. If the threat exists, it's a symptom of casual design/testing of aircraft systems

I've worked in electronics R&D labs for many years, specifically in consumer products. An essential part of the process involves subjecting circuitry to lengthy tests to detect the effects of emitted energy across the electromagnetic frequency spectrum. You may have seen the FCC label on one or more of your electronics items reading "this device may not cause harmful interference, and this device must accept any interference received, including interference that may cause undesired operation." This is applicable only to devices falling under the domain of the FCC, but the principle applies, or should, to communication, navigation and control systems used in aircraft as well. If they feel that a potential threat exists, the onus needs to be on aircraft manufacturers to correct the situation with proper shielding/grounding/error correction and other techniques.

As is, they're admitting the possibility exists that a genuine terrorist might be able to adversely affect a flight with a custom "airplane mode", instead of fixing the problem.
