Abstract

A configured aircraft flight management aid system comprises: means of interpretation receiving data taken from external instructions from an external control center, data relating to aircraft equipment failures, cabin problems and problems related to the environment of the aircraft; means of determination receiving data from the means of interpretation and determining at least one reference constraint associated with at least one parameter representative of a flight path, a reference constraint associated with a reference parameter comprising a new constraint, different from the initial constraint when the item of data effectively necessitates following a new path, different from the initial path, and a reference constraint comprising the initial constraint when the means of determination do not have access to any data relating to an event effectively necessitating following a new path; warning means generating a warning to an operator when the path actually flown does not comply with said reference constraint.

Claims

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 the aircraft is supposed to follow initially, characterized in that it is furthermore configured to have access to the effective values of said parameters, said values being representative of the path actually followed by the aircraft, said system comprising:

means of interpretation capable of receiving data D relating to events likely to necessitate the following of a new path, different from the initial path, and of determining if they effectively necessitate the following of a new path, said data being taken from among;

external instructions coming from an external control center,

data relating to aircraft equipment failures,

data relating to cabin problems,

data relating to problems related to the environment of the aircraft;

means of determination capable of receiving data D from the means of interpretation and of determining, at regular time intervals, at least one reference constraint associated with at least one parameter representative of a flight path, a reference constraint associated with a reference parameter comprising a new constraint, different from the initial constraint associated with this parameter when the means of determination have access to an item of data D relating to an event effectively necessitating the following of a new 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 path,

checking means, capable of checking, at regular time intervals, from an effective value of said at least one parameter, if the path actually flown by the aircraft complies with said reference constraint associated with this parameter; and

warning means capable of generating a warning to an operator when the path actually flown by the aircraft does not comply with said at least one reference constraint.

2. The system as claimed in claim 1, wherein the means of interpretation comprise a database, storing data relating to reference events effectively necessitating the following of a new path and means of checking that an item of data D is relative to a reference event.

3. The system as claimed in claim 1, wherein when the means of determination have access to an item of data D effectively necessitating the following of a new path, the warning means generate a warning to an operator when the path actually flown by the aircraft does not comply with said at least one reference constraint solely when a non-zero duration d has elapsed since a reference time corresponding to the reception of said item of data.

4. The system as claimed in claim 1, comprising means for determining a duration d and possibly a reference time from an item of data D.

5. The systems as claimed in claim 1, wherein said at least one reference constraint relating to a parameter comprises a tolerance regarding the compliance with said reference constraint.

6. The system as claimed in claim 1, comprising means for generating an audible or visual warning in the cockpit and/or in the cabin and/or means for transmitting a warning to an external center.

7. The system as claimed in claim 1, comprising an inhibition database listing conditions for inhibiting a warning, said warning means being capable of checking if an inhibiting condition is valid and generating a warning only if no inhibiting condition is valid.

8. The system as claimed in claim 1, comprising selection means capable of determining, when the system has access to several items of data D, a priority item of data among said items of data according to the event to which they relate, only said priority item of data being transmitted to the means of determination.

9. The system as claimed in claim 8, wherein the priority item of data is moreover selected from the following list in which the events are listed from the one of highest priority to the one of least priority:

terrain problem, warning coming from a TCAS system, windshear zone warning, storm zone, major failure, instruction coming from an external center.

10. The system as claimed in claim 1, said system being integrated in a centralized FWS warning management system.

11. The system as claimed in claim 1, wherein the means of interpretation comprise first means of interpretation able to receive data coming from first monitoring means able to be informed of cabin problems and to receive data on problems related to the environment of the aircraft and flight instructions, the first means of interpretation being integrated in a dedicated module furthermore integrating the checking means and the means of determination, the means of interpretation furthermore comprising second means of interpretation able to receive data coming from second monitoring means able to be informed of aircraft equipment failures, said second means of interpretation being integrated in a centralized FWS warning management system furthermore integrating the warning means.

12. The system as claimed in claim 11, wherein the first monitoring means comprise first acquisition means integrated in the dedicated module able to determine effective values of flight parameters from the instructions transmitted to the flight controls, second acquisition means integrated in the FMS and being able to determine effective values of flight parameters, and third acquisition means integrated in an automatic pilot device and being able to determine effective values of flight parameters from flight controls generated by this device.
