What is a 4096 code transponder?
Transponder codes This allows easy identification of aircraft on radar. Codes are made of four octal digits; the dials on a transponder read from zero to seven, inclusive. Four octal digits can represent up to 4096 different codes, which is why such transponders are sometimes described as “4096 code transponders.”
