Besides the incredible Girls With Wings scholarship (deadline November 1), there are so many scholarships out there - and those providing them are usually begging for qualified applicants!
One of the best sites I have found is: http://money2fly.googlepages.com/ (thanks to Dorothy!)
About FlightScholarship.info (from the website):
While pursuing my pilot certificates and ratings, I looked for and began to keep a listing of scholarships that I could apply for to help fund my flight training. Over time it grew and grew so I created a site and posted them on the internet to try and help others find money to fly too. Being female, I placed a special focus on cataloging grants for women. As such, much of my list contains awards for females only but there are some that are open to men as well.
Each scholarship has its own application deadline
Amounts may vary from year to year
Some awards may not be given every year
Contact the issuer for application or more info
The scholarships listed on this site are mostly one time awards of $250-$3,000 to help defray the cost of flight training for a pilot certificate or rating. The awards on this page are not restricted to collegiate aviation students only, hence are a resource for those pilot who cannot tap into all the money available to such students. This type of list was the goal of my scholarships website which I began to compile as I flight trained towards my goal of becoming an airline pilot.
