Re. Akali D. "just too much radio waves...". Of course I understand this is a hypothesis only, but I am worried that EMI could be considered as unavoidable, bound to happen. We are not taking about a brief interference with the navigation systems, but an engine shutdown! If EMI can shut down an engine, something is very wrong with the design. On the other hand, I would be curious to know how often just plain imperfect connections can cause problems, and how often these imperfections would go unnoticed because the software is robust to some extent...
