Patent ID: 8350748

Claim:
A process for automatically determining meteorological conditions in the vicinity of a reference aircraft (ACr) provided with at least one meteorological radar ( 2 ), said process comprising the steps of: determining through said meteorological radar ( 2 ), primary meteorological information associated with a primary geographical area (Zp) ahead of said reference aircraft (ACr); receiving through reception means ( 3 ) on board said reference aircraft (ACr), auxiliary meteorological information associated with at least one auxiliary geographical area (Za) and coming from means (E) being external to said reference aircraft (ACr); defining with respect to said reference aircraft (ACr), at least one space meshing (M), comprising a plurality of points (P), each one of said points (P) being representative of a geographical position and each one of said primary area (Zp) and auxiliary area (Za) being defined, at least partially, by a set of points (P) of said meshing (M); associating with each one of the points (P) of said meshing, a data related to at least one of said primary and/or auxiliary meteorological information, wherein said data comprises a type, an intensity, and a date of detection of said meteorological information; determining from said primary area (Zp) and auxiliary area (Za), a geographical area (Ze) being extended with respect to said primary area (Zp), said extended area (Ze) being defined, at least partially, by a set of points (P) of said meshing (M); and determining from said primary and auxiliary meteorological information, the meteorological conditions associated with said extended area (Ze), wherein said meshing (M) is a three-dimension regular meshing, wherein said meshing (M) is normalized to facilitate data exchange.
