Image display
First Claim
1. A method for displaying an image to a pilot of an aircraft, the method comprising:
- displaying, by a display, to the pilot of the aircraft, an image comprising guidance symbology for use by the pilot when landing the aircraft, the position of the guidance symbology on the display being dependent upon an output of an Internal Navigation System of the aircraft wherein the display is a helmet mounted display of a helmet for wearing by the pilot;
providing, to one or more processors, an indication that the output of the Internal Navigation System is incorrect;
determining, by the processor, a further value for the output of the Internal Navigation System;
determining, by the one or more processors, a specification of further guidance symbology including a position for the further guidance symbology on the display, wherein the position on the display of the further guidance symbology relative to the position on the display of the guidance symbology is dependent upon the difference between the further value for the output of the Internal Navigation System and the incorrect output of the Internal Navigation System; and
displaying, by the display, to the pilot of the aircraft, an image comprising at least the further guidance symbology.

Abstract
A method and apparatus for displaying an image to an aircraft pilot (20). The method comprises: displaying, by a display (24), to the pilot (20), an image comprising guidance symbology (34) for use by the pilot (20) when landing the aircraft (2), the position of the guidance symbology (34) on the display (24) being dependent upon an output of an INS of the aircraft (2); providing, to a processor (26), an indication that the INS output is incorrect; determining, by the processor (26), a further value for the INS output and a specification of further guidance symbology (40); and displaying, by the display (24), to the pilot (20), an image comprising the further guidance symbology (40). The position on the display (24) of the further guidance symbology (40) relative to that of the guidance symbology (34) is dependent upon the difference between the further value and the incorrect INS output.

11. Apparatus for displaying an image to a pilot of an aircraft, the apparatus comprising:
-
a display configured to display, to the pilot of the aircraft, an image comprising guidance symbology for use by the pilot when landing the aircraft, the position of the guidance symbology on the display being dependent upon an output of an Internal Navigation System of the aircraft; and one or more processors configured to; receive an indication that the output of the Internal Navigation System is incorrect; determine a further value for the output of the Internal Navigation System; and determine a specification of further guidance symbology including a position for the further guidance symbology on the display, wherein the position on the display of the further guidance symbology relative to the position on the display of the guidance symbology is dependent upon the difference between the further value for output of the Internal Navigation System and the incorrect output of the Internal Navigation System;
whereinthe display is further configured to display, to the pilot of the aircraft, an image comprising at least the further guidance symbology. - View Dependent Claims (12)
