Abstract

A standardized identification code is used to identify each flight parameter used on board an aircraft and to provide some of its characteristic information. Descriptive complementary information is advantageously associated with the identification codes to form parameter identification maps stored, for example, in a shared database. The parameter identification codes may in particular be used to perform certain checks when parameter values are received. These checks make it possible to process only the monitored parameter values and to generate alerts if an inconsistency is detected.
