ADS-B
If you have two ADS-B receivers connected simultaneously, they will compete within ForeFlight, which may lead to traffic or weather information errors. Therefore, you should only have one ADS-B receiver connected to ForeFlight at any one time.
GPS
When GPS data is provided by multiple connected devices, ForeFlight Mobile will default to the panel mount GPS data source, following a predetermined hierarchy to utilize the most accurate GPS source. If the primary GPS source is lost, the app will fall back to using the next best option based on a predetermined hierarchy.
AHRS
When AHRS data is provided by multiple connected devices, ForeFlight Mobile will default to the panel mount AHRS data source, following a predetermined hierarchy to utilize the most accurate AHRS source. If the primary AHRS source is lost, the app will fall back to using the next best option based on a predetermined hierarchy.
