Squawk 7700 tracker

Wingwait's SOS mode checks the whole world for aircraft transmitting the three emergency transponder codes and puts them on the map in red — usually within a minute of the crew setting the code.

What the codes mean

7700 is a general emergency — anything from a medical situation onboard to a technical problem. 7600 means radio failure: the aircraft is fine but can't talk to controllers. 7500 signals unlawful interference and is, thankfully, extremely rare — and often set by accident.

“Is it still an emergency?” — the question other trackers fumble

A screenshot of an aircraft that squawked 7700 an hour ago is not an aircraft in trouble now. Wingwait tracks the full lifecycle and says exactly which it is: ACTIVE EMERGENCY SQUAWK while the code is currently being received, LAST HEARD SQUAWKING 7700 · 24 min ago when the signal has gone quiet, and NO LONGER TRANSMITTING EMERGENCY CODE once the crew resets it — which usually means the situation is handled. Most 7700s end in a normal, safe landing.

Tap the ⚠ bell in the app and Wingwait notifies you the moment a new emergency appears anywhere on Earth (while the app is open).
