Get that done ASAP and have the Recruiter request AET or have that Flight Physical done (Approved from Airman Program Manager) and in your records before Cape May. (Keep a copy)
It sure would be nice to know before you go in the Coast Guard that you can pass the flight physical. (AMT,AST,AET or Pilot)
You may be able to request the Flight Phy's at Cape May or the first unit.
