Connect to an ADS-B In receiver and stay aware of potentially dangerous weather as it develops with the FAA’s new Graphical AIRMETs in ForeFlight. G-AIRMETs appear just like regular AIRMETs in ForeFlight as part of the AIR/SIGMET/CWAs map layer and can be filtered by hazard type. Unlike regular AIRMETs and SIGMETs, G-AIRMETs include a new time slider so you can filter them based on their effective times. One type of G-AIRMET, Freezing Levels, appears as its own layer, using colored lines to indicate where freezing occurs at different altitudes for the contiguous U.S.
