FAQ
What do the squawk codes mean?
7700 = General emergency — most common, covers medical issues, low fuel, and engine problems. 7600 = Lost radio contact — the aircraft can no longer communicate with ATC. 7500 = Hijacking — extremely rare and usually a transponder entry error.
Is this data live?
Yes. Data comes from the OpenSky Network, a free public ADS-B aggregator. Aircraft positions are refreshed every 60 seconds. There is a small inherent delay from ADS-B ground station coverage.
Do I need an account?
No. The OpenSky Network's anonymous API is completely free with no signup, no API key, and no rate-limiting for casual use. This tool never requires any login.
Why are there so few or no emergencies?
Genuine emergency squawks are rare. Most 7700s are brief and resolve within minutes. 7500 is extremely uncommon — pilots occasionally dial the wrong code accidentally. Most flights operate without incident.
Why is a specific flight missing?
ADS-B coverage relies on ground stations. Aircraft over remote oceans, polar regions, or areas with sparse receiver coverage may not appear. Some older aircraft use transponders with limited or no ADS-B capability.
What should I do if I see a 7500?
Nothing — you are observing a situation already being managed by Air Traffic Control and relevant authorities. They are aware and responding. Contacting airlines or airports is unhelpful and could interfere.
