Agressiveness
In 1990 I was designing some electronics packaging for aviation use and the EMC/RFI considerations were significant. Even then, there were still people (Engineers, can you beleive it!) who did not know/think that this (EMC/RFI) was a problem that needed to be addressed.
Some of the (educated?) posters on this thread may not realise it but someone in a design meeting will probably have asked the question as to the extent of the electromagnetic protection required in this plane, and this (having been decied) will have gone into the design specs. Extending the EM requirement beyond (ok, WAY beyond) what is commonly understood (your normal EMC/RFI noise from high frequency devices) is an obvious and interesting 'what if' design-impact question, which, brainpower allowing, could be asked in order simply to enjoy sharing knowledge and learn (at least some of the contributers are capable of learning).
If you want to be rude and take no pleasure from (even hypothetical) discussion then do as you say - go to JB and take your narrow minded taxi-cab driver opinions in JB. I will trade insults with you there when I become an equally sad person.
Stick at it mach 4.0
For example - they post about "civil aircraft" - as if things would have been different had the question being posted about a military aircraft????. So, tell me that no civil aircraft designs have ever been transitioned to mil-specs....suddenly your question becomes interesting to them?
