AA, hearing loss incideous. First noticed mine when flying in the Nimrod. My other nav, ex-Shack, had accute hearing and could pluck a weak radio call out of the ether. OTOH a 17,000 hr Shack and Nimrod pilot became so deaf as to be grounded.
I know we did everything we could to avoid the Quacks which might threaten our flying status. With hindsight I don't know why Serving aircrew could not have hearing aids.
