Thank you everyone!

To clarify further;

My understanding is the question relates to the worst case scenario as far as NEMP/DEW damage is concerned.

Ignoring all other scenarios about whether it is likely, whether everyone on board gets fried, what would happen on the ground, whether its a totally stupid question, etc, etc.

Just what is the worst case scenario of the NEMP/DEW damage? So although deep technical analysis of the strength of the NEMP/DEW required to cause problems is great supporting information. The answer that is really being sought is what is the likely worst case scenario as far as flight controils are concerned?

Therefore I see the answer revolves around, what would the worst NEMP/DEW damage do to the systems which

a) deploys RAT.

Airbus head of A320 team told me personally "by definition the battery bus is always operational, so RAT would deploy. But then went on to say one could have the option of manually deployiong via cable from flight deck.

b) once RAT is deployed, bearing in mind worst NEMP/DEW damage, would the stab/ rudder be available?

Even if this is a totally dumb question, I am intrigued!

My view, is that BBJ, being capable of complete manual reversion, still has a chance of being controllable, perhaps vmc only. It is quite right all flight instruments may be inop, and you are still in deep s*it. However it does seem that the aircraft has a chance of being controllable..if only by seat of the pants, and if a/c remains vmc.

So I believe, the answer this principal is intereted in is. In worst case scenario, is their a possability of the a/c being controllable, is survivability a possability, or will aircraft certainly have no flight controls.

Is this clear? to reiterate, in worst case scenario of NEMP/DEW damage are both aircraft potentially controllable and thus do both have a possability of survival.

(with hindsight the threat title is too controversial! I just wanted to stimulate debate.)
