There are many other limitations on the rating that can be found on the FAA's website but the trade-off for these limitations is that training is shorter (20 hour minimum) and does not require a medical certificate (a current and valid U.S. driver's license will work, as long as the individual's most recent application for an FAA medical certificate was not denied, revoked, suspended or withdrawn.)
There are many more details that go along with training for the Sport Pilot certificate, so we encourage you to either check out the FAA's online information or contact our airport manager, Rich MacIsaac at 413.584.7980.
