Hi Mark,
You raise some interesting issues. Unfortunately, some of the replies might lead you to believe the pprune community is a little unhelpful but the truth is that the hearing community is often not Deaf Aware and that creates communication difficulties
My understanding from what you are saying is that you would like to become a commercial pilot and are struggling to find a way forward.
I am always happy to try and help. I have lots of contacts so feel free to pm me if you like.
Good luck in your endeavours
Greg
Ps A friend of mine in Frinton is a profoundly deaf pilot!
