A method for troubleshooting an aircraft system failure, the method comprising: - displaying on at least one interactive interface associated with a hardware processor and configured for troubleshooting and repairing an aircraft system failure: - at least one or more graphic object (614, 616, 620, 618, 622, 630, 632, 634, 636) representing at least one or more aircraft system associated with the aircraft system failure, each of graphic object being configured for receiving interaction from a user, the interaction including at least one or more of: activating or deactivating one aircraft system among the at least one or more aircraft system; and activating a safeguard mechanism embedded in the activated/deactivated aircraft system; - at least one or more energy flow icon (134, 138, 142, 146) representing a direction of circulation of an energy flow; and - at least one or more macro action icon configured for performing on at least one of the aircraft system a prescribed system function (532, 534) sequence including one or more predefined system functions (532, 534) - at least one or more manual control icon for navigating to a next predefined system function (532, 534) in the sequence - activating a series of macro actions; and - carrying out a task-specific actions sequence (6A, 6B) for troubleshooting and repairing the system failure; and - performing an action not listed in the task-specific actions sequence (6A, 6B) by interacting directly with one graphic object to activate or deactivate one aircraft system among the at least one or more aircraft system for investigating a source of the system failure; characterized in that the method further comprises activating the safeguard mechanism (640, 638) to prevent the aircraft system from executing an inappropriate operating procedure by: - determining dynamically a potential risk of action not listed in the task-specific actions sequence to identify the inappropriate operating procedure; - blocking the inappropriate operating procedure; - displaying a zone at risk icon over the graphic object representing the activated/deactivated aircraft system; - displaying the potential risk on a command icon; and - requiring to drag the command icon into the center of the zone at risk icon to confirm an execution of the inappropriate operating procedure. - displaying on at least one interactive interface associated with a hardware processor and configured for troubleshooting and repairing an aircraft system failure: - at least one or more graphic object (614, 616, 620, 618, 622, 630, 632, 634, 636) representing at least one or more aircraft system associated with the aircraft system failure, each of graphic object being configured for receiving interaction from a user, the interaction including at least one or more of: activating or deactivating one aircraft system among the at least one or more aircraft system; and activating a safeguard mechanism embedded in the activated/deactivated aircraft system; - at least one or more energy flow icon (134, 138, 142, 146) representing a direction of circulation of an energy flow; and - at least one or more macro action icon configured for performing on at least one of the aircraft system a prescribed system function (532, 534) sequence including one or more predefined system functions (532, 534) - at least one or more manual control icon for navigating to a next predefined system function (532, 534) in the sequence - at least one or more graphic object (614, 616, 620, 618, 622, 630, 632, 634, 636) representing at least one or more aircraft system associated with the aircraft system failure, each of graphic object being configured for receiving interaction from a user, the interaction including at least one or more of: activating or deactivating one aircraft system among the at least one or more aircraft system; and activating a safeguard mechanism embedded in the activated/deactivated aircraft system; activating or deactivating one aircraft system among the at least one or more aircraft system; and activating a safeguard mechanism embedded in the activated/deactivated aircraft system; - at least one or more energy flow icon (134, 138, 142, 146) representing a direction of circulation of an energy flow; and - at least one or more macro action icon configured for performing on at least one of the aircraft system a prescribed system function (532, 534) sequence including one or more predefined system functions (532, 534) - at least one or more manual control icon for navigating to a next predefined system function (532, 534) in the sequence - activating a series of macro actions; and - carrying out a task-specific actions sequence (6A, 6B) for troubleshooting and repairing the system failure; and - performing an action not listed in the task-specific actions sequence (6A, 6B) by interacting directly with one graphic object to activate or deactivate one aircraft system among the at least one or more aircraft system for investigating a source of the system failure; - determining dynamically a potential risk of action not listed in the task-specific actions sequence to identify the inappropriate operating procedure; - blocking the inappropriate operating procedure; - displaying a zone at risk icon over the graphic object representing the activated/deactivated aircraft system; - displaying the potential risk on a command icon; and - requiring to drag the command icon into the center of the zone at risk icon to confirm an execution of the inappropriate operating procedure.
