Abstract

The invention relates to a process for managing the activating of emission of a given warning message in an aircraft, characterized in that it comprises the following successive steps:

• • transmission (E2), from an alert system (10) to an authorization-issuing system (20), of an emission authorization request, the said request having a priority attribute known as request priority,
  • transmission (E3), from the said authorization-issuing system (20) to the said alert system (10), of an emission authorization, the transmission of the said emission authorization being effected if the said request priority attribute is higher than a current priority threshold,
  • activation of emission of the given warning message, the said activation being effected if an alert condition associated with the given warning message is detected and if a priority attribute associated with the said alert condition is higher than or equal to the said request priority attribute.

Claims

1. A process for managing the activating of emission of a given warning message in an aircraft, characterized in that it comprises the following successive steps:

transmission (E2), from an alert system (10) to an authorization-issuing system (20), of a request to authorize emission of a warning message, the said request possessing a priority attribute known as request priority,

transmission (E3), from the said authorization-issuing system (20) to the said alert system (10), of an authorization to emit a warning message, transmission of the said emission authorization being effected if the said request priority attribute is higher than a current priority threshold.

activation (E4) of emission of the given warning message, the said activation of emission being effected if an alert condition associated with the given warning message is detected and if a priority attribute associated with the said alert condition is higher than or equal to the said request priority attribute.

2. A process according to claim 1, characterized in that the step (E4) of activation of emission of the warning message comprises a sub-step (E4′

) of transmission, from the alert system (10) to the authorization-issuing system (20), of an information item known as alert in progress.

3. A process according to claim 1 or 2, characterized in that the step (E2) of transmission of an emission authorization request is preceded by a step (E1) of activation of an alert process, comprising a sub-step (E1′

) of transmission, from the said authorization-issuing system (20) to the said alert system (10), of an information item about activation of a warning message, transmission of an emission authorization request being effected if an alert condition associated with an activated warning message is detected.

4. A process according to one of claims 1 to 3, characterized in that the said given warning message is supplemented at its beginning by a silence of predetermined duration, known as cutoff, if the emission authorization comprises a time delay order.

5. A system for managing the activating of emission of a given warning message, characterized in that it comprises:

means for transmitting a request for authorization to emit a warning message from an alert system (10) to an authorization-issuing system (20),

means for transmitting an authorization to emit a warning message from the authorization-issuing system (20) to the alert system (10),

means (210) for modulating transmission of an authorization to emit a warning message, the said transmission of an authorization to emit a warning message being effected if a priority attribute known as request priority of a request to authorize emission of a warning message transmitted from the alert system to the authorization-issuing system is higher than a current priority threshold, and

means (110) for modulating activation of emission of the given warning message, the said activation being effected if an alert condition associated with the said given warning message is detected and if a priority attribute associated with the said alert condition is higher than or equal to the said request priority attribute.

6. A system according to claim 5, characterized in that the means (110) for modulating activation of emission of a warning message include means for measuring a duration known as activation duration, counted from the transmission of an emission authorization, the activation of emission of a warning message being effected during the activation duration

7. A system according to claim 5 or 6, characterized in that the means (210) for modulating transmission of an emission authorization comprise means for measuring a duration known as prohibition duration, which can be counted from a given moment, the transmission of an emission authorization being effected after the end of the prohibition duration.

8. A system according to one of claims 5 to 7, characterized in that the means (110) for modulating activation of emission of a warning message comprise means for modulating transmission of an information item known as alert in progress from the authorization-issuing system to the alert system, the transmission of an information item about an alert in progress being effected if the alert system commands the emission of the warning message.

9. A system according to one of claims 5 to 8, characterized in that it additionally comprises

means (220) for modulating transmission, from the authorization-issuing system (20) to the alert system (10), of an information item about activation of a warning message possessing a priority attribute known as activation priority,

means (120) for modulating the transmission, from the alert system (10) to the authorization-issuing system (20), of a request to authorize emission of a warning message, the transmission of an emission authorization request being effected if an alert condition associated with an activated warning message is detected.

10. A system according to one of claims 5 to 9, characterized in that the alert system (10) being a first alert system, the authorization-issuing system (20) is a second alert system, its function including emission of at least one warning message associated with an alert condition whose detection duration in flight condition is short.
