# Radar and Squawk Panel

## Radar and squawk panel

This system adds transponder squawk codes and a radar view for authorized jobs. It helps pilots signal their status and lets police monitor aircraft in the airspace.

### Squawk panel

A squawk code is a four-digit number set on an aircraft transponder. It lets radar users identify the aircraft and quickly spot emergency conditions.

The default operational squawk is `7000` in the EU and `1200` in the US.

Pilots can change their squawk code when their situation changes. This lets them update their status without making a radio call first.

### Emergency squawk codes

Use these codes when needed:

* `7500` — Unlawful interference or hijacking
* `7600` — Lost communications
* `7700` — General emergency

### Radar panel

The radar panel is only available to certain jobs, such as police. It gives them a live overview of aircraft in the area.

The radar shows:

* callsign
* squawk code
* altitude
* speed
* aircraft model

Pilots can change their callsign with `/callsign`.

Authorized users can also attempt to contact an aircraft through the radar panel. This can be used for routine checks or to respond to an emergency squawk.

### Radar limitations

Aircraft do not always appear on radar. The system uses a radar floor, so aircraft flying low to the ground can avoid detection.
