Okay so it wasn't someones phone that did it, but this is not the first instance of aircraft instrument trouble in that area. Now what else is in the area of Exmouth? 1 : The phased antenna array, 2 : Pine gap .. Americas installation which is part of the echalon program. now both of these, the phased antenna array in particular pump out massive amounts of em interference. Since this isnt the first instance of plane trouble in the area, merely the most reported/ serious, maybe they should look into the EM in the area and see if that could be having an effect. Thats alot more EM then all the mobile phones in Perth city put together. I know the airbus systems are pretty heavily computerised, but I am not sure about how hardened they are. I know someone on here said they are an auto pilot engineer. Thoughts?
