Unless things have changed in a few years, you'll still do an applicant aviation physical at OCS. If you're at an aviation squadron, you can ask your flight doc about it or see if they could contact NAMI and get more information. Most NAMI flight docs I met either through treatment or at the HTs were great and willing to answer any questions. There were quite a few priors who either had an existing flight physical or had one down prior to OCS that had to reapply for their waviers. I would review the NAMI waiver guide to get as much informaiton as possible.
