I've just purchased an Aeronca 7AC and plan on getting a SP certificate. I've read the FAR and just get more confused each time I re-read. Is there actually a STUDENT sport pilot certificate? If so is it only issued after the practical test? If that is the case is my log book with CFI endorsement all that is needed for solo once I reach that stage? Is there a recommended time along the way to take the knowledge test? Is early in the process any better/worse than later? Thanks to those of you who have done this navigation already.Keith Wortman
