Claim:
1. A system for activating a distress beacon of an aircraft, the system being configured to determine a positional difference between a theoretical position of the aircraft determined from data of a flight plan and a real position of the aircraft determined from navigation and monitoring equipment installed in the aircraft and a control being configured to deliver an instruction to arm the distress beacon when one or more conditions are met, one of such conditions being that the determined positional difference exceeds a first predetermined value, wherein after the arming of the distress beacon, the control delivers another instruction to activate the distress beacon when an amplitude of a signal delivered by an acceleration sensor of the distress beacon exceeds a second predetermined value, and before the arming of the distress beacon, the control deactivates at least one cockpit warning based on a comparison between a first predetermined time period after the positional difference has exceeded the first predetermined value, and a second predetermined time period after the first predetermined time period when a false warning associated with the distress beacon is detected.
