1. A data updating system for computer devices included in an aircraft, the computer devices being, when the data of the computer device are updated, liable or not to affect the safety of an operator carrying out maintenance, wherein the system is included in the aircraft and comprises:
a data loading device,
a communication device,
a data router,
a module for detecting at least one maintenance operation on the aircraft, the data router being connected to the data loading device, the communication device being configured for receiving commands from a device located outside the aircraft, and
circuitry causing the system to perform:
receiving, by the communication device, a command for updating a computer device,
controlling, by the communication device, the data loading device for transferring data for updating the computer device to the data router in response to the command for updating the computer device being received,
controlling, by the communication device, the data router for transferring the updating data to the computer device in response to the command for updating the computer device being received,
detecting that at least one signal indicating that a maintenance operation is being performed on the aircraft is received by the module for detecting at least one maintenance operation, and
blocking, by the module for detecting at least one maintenance operation on the aircraft, the data for updating the computer device or at least one command for transferring the updating data in response to detecting that at least one signal indicating that the maintenance operation is being performed on the aircraft is received by the module for detecting at least one maintenance operation.
