My brother has all that income too and the VA gave him hearing aids because his hearing loss was caused by his service on the flight line.
He needs to check with the VA again.
He is in the process of going through the disability end, took a year to get the appointments. So far they are dud ones that took a big chunk of the day for useless tests not related, that has noting to do with his hearing or retinitis. That comes next month when he sees the internist type dr.
We got a FLAT NO you make to much statement even when the former ENT who was once a VA Doc said it was typical flight deck hearing loss.
