Thanks for your reply. Yes I have tried without success to contact EASA ref equipment approval date. They don’t reply it seems.
Perhaps you can answer the question I asked them.
If a set of new avionics has been flying with proven safety for more than two years, in scores of different types of aircraft in the USA, why do EASA deem it unsafe to fit and fly in Europe? And why does it take two years to check the manufacturers proven paperwork?
