I believe that in Europe there is EC legislation for the minimum level of insurance required for passenger and 3rd party liability. The numbers make interesting reading as it infers that the insurance payout should cover the kind of liability Tacan400 was trying to calculate. So, here we go with what are known as the ECAC 25-1 numbers:
B737/A320 Euro70m
B747/A340 Euro130m
HOWEVER, there is draft EC legislation to update the numbers, which uses the following:
B737/A320 Euro425m
B747/A340 Euro700m
So, this would suggest that Tacan400 was along the right lines (assuming that the draft legislation is based on the current facts).
Now, if someone is found negligent, then that would perhaps give the insurance company a 'get out'. Anyone know more about this?
