IS-0406 — Aircraft Dissemination of Information on Weather Hazards to Other Aircraft
Significant weather events captured by on-board system such as wake vortices or severe turbulence are broadcast to other airspace users.
The objective is to inform other airborne users of significant conditions, e.g. wake turbulence, icing, etc. which may be of safety concern to individual aircraft or multiple aircraft (e.g. increased vertical separation).
