You don't say whether you fly for an airline, as a corporate pilot or privately.
In the United States, many contracts of unionized pilot groups contain a clause that guarantees the Company will indemnify the flight crew in any litigation resulting from on the job accident/incident, unless a result of the pilot's willful intent. Premiums are paid by the Company.
If you have an estate to protect, you should be insured. If you are an airline pilot with a union, this should be a part of your contract, IMO.
