If you're owner of the ADS-B setup RealADSB app can show air traffic in close vicinity on a big (or very big) screen TV connected to Apple TV. In order to optimize ADS-B feed you will need FREE Java server application called adsb_hub running on desktop, laptop or Raspberry Pi 2+. Also USB receiver and antenna with good sensitivity on frequency 1090MHz are necessary. Wi-Fi is used to establish connection between Apple TV 4th generation (tvOS 10+) and adsb_hub server application. Using different configuration files on server you can pull the data from dump1090/PiAware or directly from USB receiver.
