Method and device for automatically adjusting an image of an aircraft navigation screen

A method for automatically adjusting an image of a navigation screen (2) of an aircraft, said navigation screen (2) being capable of displaying an image according to one of a plurality of different display modes and with one of a plurality of different scales, according to which method, in a step a), a monitoring of the environment of the aircraft is performed automatically so as to be able to detect an event liable to be dangerous for the aircraft, wherein the following step b) is carried out moreover, in an automatic manner:

• b) if such an event is detected in step a):
• b1) the display implemented on the navigation screen (2) is analyzed so as to be able to detect the necessity for a change of display corresponding:
• to a change of display mode;
• and/or
• to a change of scale;
• b2) if the necessity for a change of display is detected in step b1):
• α) a new display configuration is determined, namely a new display mode and/or a new scale, which is suited to the current environment of the aircraft and which makes it possible to present on the navigation screen (2) the event detected in step a);
• and
• β) a change of display of the navigation screen (2) is carried out automatically by applying thereto the new display configuration determined in step a).

A device for automatically adjusting an image of a navigation screen (2) of an aircraft, said navigation screen (2) being capable of displaying an image according to one of a plurality of different display modes and with one of a plurality of different scales, said device comprising monitoring means (3) for performing an automatic monitoring of the environment of the aircraft so as to be able to detect an event liable to be dangerous for the aircraft, wherein it comprises, moreover:

• first means (4, 5) for automatically analyzing the display implemented on the navigation screen (2), if such an event is detected by the monitoring means (3), so as to be able to detect the necessity for a change of display corresponding:
• to a change of display mode;
• and/or
• to a change of scale;
• second means (8, 9) for automatically determining, if the necessity for a change of display is detected by the first means (4, 5), a new display configuration, namely a new display mode and/or a new scale, which is suited to the current environment of the aircraft and which makes it possible to present on the navigation screen (2) the detected event;
• and
• display means (12) for automatically carrying out a change of display of the navigation screen (2), by applying the new display configuration determined by said second means (8, 9).
