Great places to start networking with other pilots and aviation professionals can vary from a pilots’ lounge in the local FBO, to the airport cafe get-together Friday evenings, to Internet chat rooms and message boards.

Just by letting people know that you are interested in a career or hobby that they are already participating in will bring lots of advice. Fly-ins are also a great way to get started. They can range from a pancake fly-in that attracts a few dozen pilots all the way to the AOPA, Sun ‘n Fun, and Oshkosh fly-ins that attract thousands of people each year.
