Yesterday, I became an AOPA (Aircraft Owners and Pilots Association) member. Around 66 years into existence, AOPA is probably the world's largest non-profit association of pilots (2/3rd of American pilots are AOPA members). It represents pilots' and aircraft owners' interests at the federal and state level. For the representation purposes, it has a separate wing called AOPA Legislative Affairs. AOPA has chapters worldwide, and has considerable say in aviation affairs. AOPA has been quite involved in promoting the interests of GA (General Aviation) scenario in the US, something we desperately need in India.
