I got my Private Pilots Cert many years ago, but have not flown in a number of years. I am now taking steps to get curent on everything and begin flying again. I even bought an interest in a plane. I have taken my medical exam but am waiting on FAA response regarding any special requirements. Must I have the Med Cert in hand before flyin with a CFI? Keep in mind, I already have my pilot cert and am just wanting to take lessons to "refresh" thoroughly. I do understand that I will have to have the Med Cert to checkride.
