AC ZERO What's the meaning of ....

HI EVERYONE, I'M A RECENT PROUD OWNER OF AC ZERO AND I'V FINISHED IT ONCE. COULD ANYONE EXPLAIN THE MEANING OF THE SYMBOLS (SQUARE, TARGETS, ETC.) THAT APPEAR UNDER THE PLANE'S NAME YOU POSSES IN THE HANGAR SCREEE.

THANK TO ALL AC FANS

Try Heat Seeker, heh. I dont really know what the symbols mean but if i had to guess its probably just a quick way to tell either what type of planes they are(fighter,bombers, both) or what they are loaded out with(air2surface, bombs, air2air).
