aviation medicals
I just had an avmed (not with cathay) and they tested for:
reflexes
colour blindness
eyesight
Stigmitism and associated eye tests
Hearing and looking at the ear drums etc...
check for hernes!
electrodes on different bits of the body. ecg
blood test
urine test
listening to the beat of the heart..etc
and much more
cant remember anything else. but there is more. The doctor said that they are checkin for any lasting and non repairing injuries that may may affect your flying. I hope this helps. I had a shoulder injury that was quite serious and the doctor didnt seem too bothered.
Hope this helps.
