Flight Med should contact you after you make that request in IMR, but I would just give them a call. Flt med should send you and make you fill out several papers and then schedule a audiogram, labs, optometry, and chest x-ray. The paperwork is like family history, disclosure stuff, and etc. I highly recommend you call your flight medicine off and See what they would like. After all this you will have an appoint with the flight doc and he will examine you.
