Sorry, dont know which 'CAA' or JAA form you filled out, but mine had lots of questions, and when the subanswers were added went near the NZ number.
We all hate forms, but I am not sure what the winge is. Incapacitation in the air kills pilots, passengers and the public. Ensuring you are not an unacceptable risk involves a lot of questions simply because non doctors dont understand the relevance; your ignorance of your father's death being significant - he may have had an inherited musculoskeletal disorder so you would need to be excluded - makes my point.
If the quaestions allow the AME to more easily exclude issues in your medical history so much the better.
If NZ grounds pilots for being left handed you have a winge, but if they ask you loads of questions and then give you a medical you dont.
