US 7,127,683 B2 · Method to detect application spoofing in mixed use avionics display

Abstract

A method to detect application spoofing in a mixed use avionics display by indicating when a mixed use avionics display is displaying information from a non-certified source. The method comprises providing an avionics display having a display area that is capable of displaying information from a non-certified source. A data connection is established between the non-certified source and the avionics display. Information is provided from the non-certified source to the avionics display through the data connection. The information from the non-certified source is then displayed on the display area so that less than the entire display area is used in displaying the information. The displaying of information from the non-certified source on less than the entire display area gives a visual indication that the information being displayed on the avionics display is from a non-certified source and susceptible to interference by a remote party and possible application spoofing.

A method of detecting application spoofing in a mixed use avionics display by indicating when the mixed use avionics display is displaying information from a non-certified source, the method comprising the steps of:

providing an avionics display having a display area that is capable of displaying information from a non-certified source;
displaying a certified display on the display area;
providing a data connection between the avionics display and the non-certified source;
providing information from the non-certified source to the avionics display;
displaying the information on the display area so that less than the entire display area displays the information;
maintaining the displaying of the certified display on the display area while simultaneously displaying the information from the non-certified source;
displaying the information on the display area in front of the certified display so that the information is visible on the avionics display, at least a portion of the certified display is visible on the avionics display and the information covers a portion of the certified display that would otherwise be displayed;
and
indicating to a user that application spoofing is possible by partitioning the display area so that at least a portion of the display area cannot display the information from the non-certified source.

A method of allowing an aircraft certified flight deck display to be used as a mixed use avionics display by indicating when the certified flight deck display is displaying information from a non-certified source, the method comprising the steps of:

providing an aircraft having a certified flight deck display;
providing a data connection between the certified flight deck display and a non-certified source of information;
providing information from the non-certified source to the certified flight deck display;
limiting space on the certified flight deck display in which the information can be displayed so that an entire display area cannot be used to display the information by partitioning the display area so that at least a portion of the display area cannot display the information from the non-certified source;
providing the non-certified source with a false indication of the size of the display area so that the non-certified source is not capable of addressing the entire display area;
and
indicating that a potential for application spoofing exists by displaying the information in the limited space on the certified flight deck display.
