Which code is assigned to a VFR departure that is not in communication with an ATC facility?

The code assigned to a VFR (Visual Flight Rules) departure that is not in communication with an ATC (Air Traffic Control) facility is 1200. This code is used by pilots flying under VFR conditions who have not established communication with ATC. When a pilot operates under VFR, they are expected to maintain visual separation and fly in accordance with the rules that govern their specific airspace.

Using code 1200 indicates that the aircraft is operating in VFR and is not receiving ATC services. This is the standard transponder code for general VFR operations, ensuring that the aircraft can still be depicted on radar for situational awareness while staying clear of controlled airspace, unless otherwise indicated.

The other codes serve different purposes: 7700 is used for general emergencies, 7600 indicates a loss of communication, and 4000 is not a standard code associated with VFR operations. Understanding these distinctions helps pilots and controllers communicate and manage air traffic effectively.
