The invention relates to a method for verifying a character to be displayed on a screen, compared to a reference character. The character to be displayed and the reference character each comprise at least several characteristic points. The method comprises: The character to be displayed is considered correct only if the computed deviation is below the predetermined threshold.

Method and electronic device for verifying a character to be displayed on a screen compared to a reference character, associated computer program product and graphics processor

Device for viewing the aerial environment for aircraft, including a display, a processor and memory configured to generate and to provide a first data processing resource, the data being a graphical representation of the aerial environment composed of colored zones, each color being associated with a danger level for the aircraft, said data comprising environmental data; and a second data processing resource for cartographic data. The device further comprises a graphical mixer to overlay the graphical representation arising from the environmental data onto a representation of the cartographic data on one viewing screen, each zone of a color of the representation of environmental data having a transparency coefficient dependent on the danger level.

Viewing device intended for comprehending the aerial environment

Device for servoing graphical representations of the aerial environment for aircraft, an avionics the device including a display, a computer and memory in communication with the computer, the memory storing means for generating images of environmental data, said data being servoed by the first calculation resource and periodically refreshed in a first time interval. The device comprises a calculation resource providing an angle of heading of the aircraft relative to North and its geo-referenced current position, these data being servoed, periodically, in real time in a second time interval. The representation of a part of the environmental data on the viewing screen of the device is servoed and refreshed during the second time interval and positioned and oriented graphically, by the display, according to the last current angle of the position of the aircraft calculated and of the last geo-referenced current position.
