Method and system for aiding the navigation of an aircraft

A method for aiding the navigation of an aircraft, via a system comprising:

• at least one navigation database;
• a display system comprising at least one display screen capable of displaying navigation information;
• and
• a central unit connected to said navigation database which manages the display implemented by said display system, and which comprises at least one unit for receiving current parameters relating to the aircraft and its environment based on performance data for the aircraft, a flight phase of the aircraft, and a trajectory of the aircraft, said method comprising the steps:
• performing a contextualized filtering of the information intended to be displayed on said screen and originating at least in part from a global type of navigation database, said database containing all the data necessary for the air navigation and airport navigation of the aircraft, as well as data given on navigation maps, said contextualized filtering being performed in accordance with predefined rules depending on current parameters relating to the aircraft and its environment, and comprising at least the following parameters:
• performance data of the aircraft, the flight phase and the trajectory of the aircraft, and dynamic parameters updated in real time, said contextualized filtering comprising different levels of contextualization, and at least one of the following levels:
• a selection of information with a view to display relevant to a given context;
• a highlighting of displayed information for the given context via visual signals;
• and
• an offer of access to information displayed in a separate graphic element having at least one text instruction relating to a current flight phase;
• and wherein said contextualized filtering is performed based on said current parameters and said levels of contextualization;
• and
• displaying on one and the same screen, namely on said display screen, information produced by said contextualized filtering such that the information required by the contextualized filtering is displayed on said display screen.

An aircraft comprising:

• a system for aiding the navigation of an aircraft, said system comprising:
• at least one navigation database;
• a display system comprising at least one display screen capable of displaying navigation information;
• and
• a central unit that is connected to said navigation database, which manages the display implemented on said display system and which comprises at least one unit for receiving current parameters relating to the aircraft and its environment based on performance data for the aircraft, a flight phase of the aircraft, and a trajectory of the aircraft, wherein:
• said system comprises at least one navigation database of a global type, which contains all the data necessary for the air navigation and airport navigation of the aircraft, as well as data given on navigation maps;
• said central unit configured to perform a contextualized filtering of the information intended to be displayed on said display screen and originating at least in part from said navigation database of a global type, said contextualized filtering being performed in accordance with predefined rules depending on said current parameters relating to the aircraft and its environment, comprising at least the following parameters:
• the performance data for the aircraft, the flight phase and trajectory of the aircraft, and dynamic parameters updated in real time, said contextualized filtering comprising different levels of contextualization, and at least one of the following levels:
• a selection of information with a view to display relevant to a given context;
• a highlighting of displayed information for the given context via visual signals;
• and
• an offer of access to information displayed in a separate graphic element having at least one text instruction relating to a current flight phase;
• and wherein said contextualized filtering is performed based on said current parameters and said levels of contextualization;
• and
• said display system produces a display on one and the same screen, namely on said display screen, of information produced by said contextualized filtering performed by the central unit such that the information required by the contextualized filtering is displayed on said display screen.
