Introduction
Squawk codes are issued to aircraft as part of their Airport clearance,
as well as issued to Aircraft entering an ACC airspace. Also known
as SSR's (Secondary Surveillance Radar) or Transponder Codes, a
Squawk Code is a radio identity code that allows a specific aircraft
to be identified on a radar scope by its own specific code.
In Pro Controller a Call sign is shown on radar by default, unless
an aircrafts flight plan has not been sent or received and we would
then see a Squawk Code.
Squawk Codes
In TURKEY Squawk Codes for commercial and emergency use in Numerical
Order (controllers are advised to be careful when issuing squawk codes
7000 and above due the close proximity of the Special Purposes Codes)
