Perhaps they aren't willing to assume that the electronics in planes are as shielded as they're supposed to be.
What confuses me is why they don't ensure that planes' electronics are properly shielded rather than testing a bunch of electronics that emit very weak to weak EM. If a cell phone could create problems for a flight during take-off, what about a lunatic pointing a HERF weapon at the plane?
- HeyLaughingBoy 15y agoShielding is only part of the battle; the other part is what they're doing here: controlling incoming emissions. Nothing can be perfectly shielded in the real world and instruments or controllers may need very long cables to connect to their respective sensors and actuators making shielding difficult. Now add in that many of these instruments actually need to process an RF signal and so won't work if shielded, and it becomes a difficult problem to solve.
