1. A method for automatically monitoring a flight path of an aircraft during at least one required navigation performance operation, comprising the steps:
- determining said flight path, which is intended for the required navigation performance operation, by a flight management system of the aircraft using navigation data stored in a database on board the aircraft,determining, on the ground, during a validation of the navigation data intended to be stored in said on-board database, a path using a simulator which simulates the functioning of the aircraft, and to which said navigation data are applied, the path thus determined being considered to be the reference path,said method also comprising the following steps a) and b), taking place on the aircraft, of;
a) logging the reference path in a memory on board the aircraft, said memory being independent of a sequence for calculating the flight path comprising at least said flight management system, the reference path representing the path defined in the previous step during the ground validation of said navigation data; and
b) using said reference path to monitor a current flight path determined by the flight management system by verifying the consistency between said current flight path and said reference path.

Abstract
A monitoring device including a memory containing a reference path, the memory being separate from a flight management system. The reference path corresponding to a path that is defined during a navigation data validation on ground for the flight management system. A monitoring unit is configured to monitor a current flight path that is determined by the flight management system, by monitoring if this current flight path is in conformity with the reference flight path that is recorded in the memory.
