A method for updating a software application stored in an equipment item on board an aircraft. The method comprises downloading update files to an on-board dataloader, checking the integrity and authenticity of the new software application version, transmitting this new software application version to the equipment item concerned, storing the new software application version in question into a standby memory zone of said equipment item, while this equipment item is still controlled by a previous version of said software application stored in an active memory zone, distinct from said standby memory zone, and finally, switching said standby and active memory zones, said equipment item being then controlled by the new software application version stored in the active memory zone after the memory zones have been switched.
