System and method for managing audio warning messages in an aircraft

Abstract

The present invention relates to a system (1) and an associated method for managing audio warning messages in an aircraft. The system (1) comprises a plurality of monitoring systems (10, 20) capable of detecting the establishment of at least one warning condition (CA), and comprises a central broadcasting module (40), to which each of the monitoring systems is connected and which is capable of broadcasting an audio message (SIG) corresponding to a detected warning condition. In particular, in this system (1), the said central broadcasting module (40) comprises means (402, 420) for determining at least one priority warning condition among the warning conditions detected by the monitoring systems, and means (410, 430) for generating at least one audio message (SIG) corresponding to the at least one determined priority warning condition, in order to broadcast it.

Description

technical field [0001] The present invention relates to systems and methods associated with the control of alert sound messages in aircraft. Background technique [0002] In the cockpit of an aircraft, different monitoring systems are responsible for sending alarm messages in case of abnormal conditions detected, which are used to alert the crew. [0003] These systems together form an overall alert system: the on-board system used to notify the crew of abnormal conditions involving the aircraft (stall, overspeed) or the aircraft's monitored systems. [0004] The monitored system may include detectors or computers related to, for example, the engine, fuel tank or landing gear. [0005] An example of a monitoring system is a monitoring system for flight conditions (or FWS - Flight Warning System). The system can, for example, issue an alarm when flight conditions are abnormal, and can also issue an automatic report of the altitude when the aircraft passes a certain altitude...

AI Technical Summary

Problems solved by technology

These cables thus weigh the aircraft

[0023] Second, there is at least one audio circuit board at each monitoring system level, which causes an increase in the cost of these systems

Furthermore, this complexity makes the development of systems implementing the protocol slow, especially for the integration of a new surveillance system

[0025] Finally, the addition of new alarm conditions and thus new alarm sound messages is relatively complex and expensive, not least because the information encoding of each of these relevant monitoring systems has to be intervened
