Want to fly for fun? Become a Sport Pilot! You'll get to fly recreationally in Light Sport Aircraft, and even take a passenger with you. No medical certificate is required, as long as you have a valid Driver's License!
As a CFII, you can teach students who are looking to earn their Instrument Rating, or fellow CFI's who want to get their CFII add on.
Our Flight School in Los Angeles has what you need to become a CFII!
