The Radar (Lowest-Tilt) layer only depicts radar returns obtained at the lowest angle of the radar’s sweep, which better correspond to where precipitation is reaching the ground in the form of rain or snow.
The new layer benefits from significantly reduced latency of six minutes or less and also provides enhanced spatial resolution, although the layer doesn’t yet support storm track markers.
Release 16.4 also provides enhancements to ForeFlight’s Runway Analysis product for jets and select turboprops, including an expanded workflow for selecting your flight’s Landing Distance Factor and a printer-friendly TOLD card for pilots.
