If you do happen to know what you are talking about (as you claim), go ahead, give a technical explanation why the A320 will "spin out of the sky" as you put it.
At no stage did I ever say an A320 will 'spin out of the sky', so I won't answer that. I have no idea what it will do. Any facetiousness is down to the pointlessness of discussing a wholly hypothetical situation of an upper atmosphere EMP burst when most knowledge is classified anyway, virtually no aeroplane can be protected, and if it should occur, people aloft in an aeroplane will not be high on the agenda with all the damage on the ground with the infrastructure and communications completely down. So who do you want to answer and what sort of answer can you expect of them?
<<the possability must surely exist that one day an aircraft could be affected by NEMP or DEW>> I totally disagree with this assertion.
And my handle is
Rainboe, which you should recognise if you were a Boeing pilot, and I have 39 years as a real pilot behind me, and 34 years on jets, and 18,500 flying hours. Call me when you approach any of those totals and you will then have respec'!
