Special codes:

7700 - Emergency, this will be an indication on the controller's screen that your aircraft has experienced an emergency.

7600 - Communication Failure, this code is not used very often on IVAO because we have both Text and Voice communications. If you would like to simulate lost comms procedures, make sure to check with your controller first.

7500 - Hijack, this code is a part of the tutorial for information only. Although terrorism and war exist in the real world we in IVAO do not allow the simulation of any kind of aggression or armed violence on our network.

For Visual Flights:

Codes for all visual flights: 7000, 7001, 7002, etc.

Pilots! If your departure aerodrome placed in uncontrolled airspace,
please, don't set your own squawk! In this cases, use the default transponder code: 2000.
