ON PATH WEATHER VS. OFF PATH WEATHER

The ALL/ALL WX and ON PATH/ PATH WX modes are used for the
strategic detection of weather. This fully automatic weather detection is
enabled by the 3D volumetric memory. In these modes, on path
weather, or weather near the altitude of the intended flight path, is
displayed as distinct from off path weather, which is further removed in
altitude from the flight path. The result is a presentation of weather
information that is intuitive, improves awareness of the entire weather
situation, and reduces the potential for misinterpretations, thus reducing
crew workload.
The separation of on path from off path weather is based on several
parameters:

Aircraft altitude

Flight phase (climb, level flight or descent)

Flight path

Presence of convective weather.
