Airsense is not currently available outside the USA,  even if your drone physically has it, it will detect location and disable the feature.

Airsense is a DJI branded name for the standardized aviation protocol called Automatic Dependent Surveillance–Broadcast (ADS-B).

ADS-B distances are based on the signal strength of the transmitter which should have a standardized frequency and wattage output.  The hight and distance of the signals viability can vary greatly due to terrain and and atmospheric conditions.  But in general, from personal experience, the range is around 5-7 miles when an aircraft is at a significant altitude.

Only in North America has the ADS-B protocol widely been widely mandated and implemented.  The biggest issue with the effectiveness of ADS-B is the low level of adoption in other countries and the mandatory implementation  being delayed for non commercial aircraft.  Here is EU https://ads-b-europe.euwebsite for ADS-B implementation.  Although, the United Kingdom is no longer a member of the EU this information may be helpful starting point to better understand the mandate and adoption of ADS-B.

One of the nuances of ADS-B is that it transmitter to receiver based and does not use ground station repeaters.  I had an incident flying on the coastline in San Diego.  A low flying aircraft was flying at about 250ft altitude about 400ft from coast.  The signal was obstructed by the coastline mountains.  By the time the aircraft came round the coastline and the signal was no longer obstructed by terrain the aircraft was within a few thousand feet of my drone.   An emergency warning popped up about 5 seconds before the aircraft was a my drones location.  This was enough time to descend from 150ft to 35ft to clear the airspace.

When I last checked the Mavic Air 2 sold outside North America was not equipped with an Airsense reciever.

Hello there Ninja63. Good day and thank you for these information you have given on this matter. In addition to this the DJI AirSense is an alert system that uses ADS-B technology to give drone pilots enhanced situational awareness and help them make responsible decisions while flying. This feature gathers flight data sent automatically from nearby aircraft with ADS-B transmitters, analyzing it to detect potential collision risks and alert users well in advance through the DJI mobile application. In addition I will post a DJI link where in you can read more about the DJI AirSense ( https://www.dji.com/flysafe/airsense ). Thank you.
