After January 1, 2020, DJI will be including AirSense technology in all consumer drones weighing more than 250 grams. This will allow drones to receive ADS-B signals from nearby airplanes and helicopters and warn drone pilots if they appear to be on a collision course. AirSense can detect airplanes and helicopters from miles away – farther than a drone pilot can hear or see them.
