Abstract:
1. An aircraft flight management aid system configured to have access to a flight plan comprising initial constraints relating to respective parameters representative of an initial flight path that an aircraft is supposed to follow initially, the initial constraints corresponding to values that values of respective parameters must take or ranges of values wherein the values of respective parameters must be included and is furthermore configured to have access to the effective values of said parameters, said values being representative of a path actually followed by the aircraft, said system comprising: means of interpretation configured to receive data D relating to events likely to necessitate the following of a new path, different from the initial path, initial constraints corresponding to values that the values of respective parameters must take or ranges of values wherein the values of respective parameters must be included when receiving a datum D, to determine if said datum effectively necessitate that the aircraft follow a new flight path different from the initial flight path, said data being taken from among: means of determination configured to receive data D from the means of interpretation and to determine, at regular time intervals, at least one reference constraint, representative of unexpected flight path, each reference constraint being associated with one parameter among said parameters, the reference constraint associated with said parameter comprising a new constraint, different from the initial constraint associated with said parameter when the means of determination have access to a datum D relating to an event effectively necessitating the following of the new flight path, different from the initial path, and a reference constraint comprising the initial constraint associated with this parameter when the means of determination do not have access to any data D relating to an event effectively necessitating the following of a new flight path, checking means configured to check, at regular time intervals, if an effective value of at least one reference parameter among said parameters complies with said reference constraint associated with said reference parameter, the effective value of a reference parameter being representative of a flight path actually flown by the aircraft; and warning means capable of generating a warning to an operator when the effective value of said reference parameter does not comply with said reference constraint.
