I have a similar problem. I've passed all phases of the interview with a mid-eastern airline and apparently I've been told that in my left ear I have moderate hearing loss (up to 60dbs I think the Dr said). I didn't realize it was so bad as I fly at the moment for an airline on my FAA license and though I've felt my left ear is weak, I can still hear from it.
Anyway, from the UAE GCAA, do I have any hope of passing an Initial Class one medical or not?
