Squawk 7000: VFR conspicuity (ICAO / Europe)
Squawk 7000 is the standard VFR conspicuity code in the UK, Europe and many other ICAO countries.
Squawk 7000 is the VFR code used in the UK, Europe and many other countries. It does the same job as 1200 in the US: it shows a VFR aircraft that is not receiving an air traffic service.
What 7000 means
ICAO recommends 7000 as the conspicuity code for VFR flights that have not been assigned another code. Most European states, the UK and many countries in Africa, Asia and the Middle East follow that recommendation. The US and Canada are notable exceptions and use 1200.
Why you might see 7000 in US data
- Foreign-registered aircraft whose pilots are used to European procedures.
- New or imported transponders set to a default of 7000.
- Typos by pilots meaning to set another code.
It is harmless, but it is worth knowing because 7000 sits close to the emergency codes. A pilot dialling 7000 on an old rotary transponder can pass through 7500, 7600 or 7700, which is why tracker data sometimes shows a flash of an emergency code followed by 7000.
How 7000 appears on heywhatsflying
Within our US box you may see 7000 on light aircraft near the Canadian or Mexican border, or on the occasional foreign-registered aircraft. It is not highlighted as anything special. For more on emergency-code false alarms, see emergencies now.
VFR codes around the world
| Region | Typical VFR code |
|---|---|
| United States, Canada | 1200 |
| United Kingdom, most of Europe | 7000 |
| Australia | 1200 |
| Many ICAO states in Asia, Africa and the Middle East | 7000 or a locally published code |
Local rules always take priority, so pilots check each country's aeronautical information publication before flying there.
Related codes: 1000 (European IFR Mode S conspicuity) and 2000. See the squawk code index.
Questions
What does squawk 7000 mean?
It is the VFR conspicuity code used in Europe, the UK and many ICAO countries. It is the equivalent of the US code 1200.
Why is 7000 linked to false emergency alerts?
On older transponders that change one digit at a time, setting 7000 can pass through 7500, 7600 or 7700. Pilots are trained to avoid this, but brief false readings still appear in data.
