A device for monitoring a plurality of systems of an aircraft, the said monitoring device including at least: - a monitoring unit for monitoring the said systems and for detecting any failure of one of the said systems; and - display means linked to the said monitoring unit and capable of presenting, on at least one visual-display screen, information relating to the monitoring of the said systems, and, upon detection of a failure of one of the said systems, information relating to the said failure, as well as at least one corresponding failure-handling procedure comprising at least a list of actions having to be carried out by at least one operator; namely if appropriate, a list of the actions already carried out relating to the said failure-handling procedure; and if appropriate, a list of the actions still having to be carried out relating to the said failure-handling procedure, highlighting the next action having to be carried out, as well as one characteristic sign signalling the completion of this failure-handling procedure; - an information means capable of being actuated by the said operator and allowing the latter to inform the said monitoring device, if appropriate, of the carrying-out of at least one particular action relating to the said failure-handling procedure; - a validation means capable of being actuated by the said operator and allowing the latter to validate information which he has supplied to the said monitoring device, information previously supplied not being taken into account by the said monitoring device unless it has actually been validated by the operator, characterized in that the said monitoring is a centralized device of the ECAM type, in that the said display means, upon detection of a failure and at least throughout the corresponding failure-handling procedure, display, on the said visual-display screen, at least an information identifying the said failure-handling procedure, and in that the said monitoring device further includes: - a deletion means capable of being actuated by the said operator and allowing the latter to delete from the said visual-display screen all the information relating to a failure-handling procedure; - an information means capable of being actuated by the said operator and allowing the latter to inform the said monitoring device of the occurrence of a failure that cannot be detected by the monitoring unit; and - an interrogation means capable of being actuated by the said operator and allowing the latter to ask the said monitoring device to have the display means present, on the said visual-display screen, the failure-handling procedure relating to the said failure. - a monitoring unit for monitoring the said systems and for detecting any failure of one of the said systems; and - display means linked to the said monitoring unit and capable of presenting, on at least one visual-display screen, information relating to the monitoring of the said systems, and, upon detection of a failure of one of the said systems, information relating to the said failure, as well as at least one corresponding failure-handling procedure comprising at least a list of actions having to be carried out by at least one operator; namely if appropriate, a list of the actions already carried out relating to the said failure-handling procedure; and if appropriate, a list of the actions still having to be carried out relating to the said failure-handling procedure, highlighting the next action having to be carried out, as well as one characteristic sign signalling the completion of this failure-handling procedure; - an information means capable of being actuated by the said operator and allowing the latter to inform the said monitoring device, if appropriate, of the carrying-out of at least one particular action relating to the said failure-handling procedure; - a validation means capable of being actuated by the said operator and allowing the latter to validate information which he has supplied to the said monitoring device, information previously supplied not being taken into account by the said monitoring device unless it has actually been validated by the operator, - a deletion means capable of being actuated by the said operator and allowing the latter to delete from the said visual-display screen all the information relating to a failure-handling procedure; - an information means capable of being actuated by the said operator and allowing the latter to inform the said monitoring device of the occurrence of a failure that cannot be detected by the monitoring unit; and - an interrogation means capable of being actuated by the said operator and allowing the latter to ask the said monitoring device to have the display means present, on the said visual-display screen, the failure-handling procedure relating to the said failure.
