Thanks for this - now a Concrete example from earlier today;
Phone up Florida flight school, they offer C172 at 150 USD wet plus Another 60 for instructor per airbore hr. So far so good, now asking for the contract on mail, I can see that there is 100% personal and unrestricted liability for the hull in case of causing any damage to the Aircraft - this will also include loss of income, third party damages etc in case we have an accident. Now, I agree that the 2-300 USD mentioned here for liability is fine, but where can I find an insurer who will sell me only the Insurance for the excess ? I tried two large firms from flying Magazine but have only got the ridiculous quote above. Best
