Sometimes it’s as Simple as Knowing Where to Look

Get help in “seeing and avoiding” with dynamic traffic display in ForeFlight. Receive air-to-air traffic information from ADS-B Out equipped aircraft and rebroadcast traffic information from FAA ground towers (ADS-R / TIS-B).

Note that if your aircraft is not ADS-B Out equipped, your view of traffic may be limited.
