When flying into Essendon, what is the appropriate squawk code?

When flying into Essendon, the appropriate squawk code is 3000. This code is specifically used for VFR (Visual Flight Rules) flights in controlled airspace when approaching or departing airports. It helps air traffic control to identify and track VFR traffic more effectively.

In the context of flying, squawk codes are essentially transponder settings that aircraft use to communicate their presence to air traffic control. The 3000 code indicates that the aircraft is operating under VFR conditions, which is typical for local traffic that does not require additional services from air traffic control. Using the correct squawk code ensures that the aircraft is visible to radar, thus enhancing safety and situational awareness in the busy air traffic environment around Essendon Airport.
