Back in 1993 I was awarded £3500 as a lump sum War Pension by the MOD for hearing loss due to service in the RN as a pilot in the 1960's - I'd also had tinnitus for years. It was time limited for applications and you could almost visualise queues outside the appointed examiner, Aberdeen Hearing Services, as all the ex-service helicopter pilots on North Sea ops tried their luck for a payment.
At that time the hearing loss was not sufficient to lose my civvie pilots licence but now I wear two hearing aids. Funnily enough because I now hear more the effect of the tinnitus is less pronounced.
