"This is november-seven-nine-echo-sierra-uniform" - a radio message from an imaginary airplane N79ESU. If you always use these phonetic substitutions when spelling names and other important data over noisy communication channels, you will minimize the possibility of error. More importantly, you will be more likely to be identified as what Roger Bacon refers to as a Total Aviation Person in his column in Flight Magazine.

The quiz program displays a letter and pauses for a certain length of time before displaying the correct word substitution. After another pause, another randomly selected letter is shown and the process continues. Your faithful quizmaster will continue until you can call them all with proficiency.

There are three other quizzes included with the program - Morse code and some dimensionless numbers of fluid mechanics and three-letter airport codes. Of course, the main idea here is to show you how to set up such a program so you can create the tables for the subject you need to learn. Some other suggestions are

  1. State capitals
  2. Capitals of various countries
  3. Foreign language vocabulary drill
  4. Important supreme court cases
  5. Nicknames of sporting teams
  6. Names of airplanes, e.g. P-51 == Mustang

The complete source code for the program is included and you should be amazed at its short length. This program is written in Delphi, so the use of the Windows Application Programming Interface in nearly invisible. You will need a Delphi compiler to modify the program, but you do not need the expensive versions. This program was written with the Standard version, which is quite reasonably priced.
