I may be missing something here, but why would your pension provider be concerned/interested?
After all, they are the reverse of a Life Insurer, they only pay out if you DON'T die...
Some companies provide a pension and life cover combined.
My company has a 4x salary "Death in Service" benefit attached to my pension.
I declared my flying interest to them and got it comfirmed "in writing" that in the event of anything happening it would make no difference to the payout and neither my company nor I had to pay anymore.
Verbally being told it was ok was no good to my relatives in the event of a dispute.
