This database created by Tom Riley will help you learn the ICAO (International Civil Aviation Organization) codes. This is a United Nations department but the code was initially created by the U.S. Military. These are the official names for the letters of the alphabet as used by the aviation world.

To view this free database on your device you will need the SuperMemory application. It will allow you to learn the cards up to 10-50 times faster and ensure that you never forget them again.
