Method and apparatus for display of an image to a pilot of an aircraft
First Claim
1. A method for displaying an image to a pilot of an aircraft, the method comprising:
- acquiring, by one or more processors operatively linked to a helmet mounted display, a first value, the first value being a measurement of the velocity of the aircraft relative to a runway upon which the aircraft is to be landed;
displaying, by the helmet mounted display, to the pilot of the aircraft, a first image component, the position of the first image component on the helmet mounted display being dependent upon the first value, said position of the first image component being a horizontal position relative to the helmet mounted display;
displaying, by the helmet mounted display, to the pilot, a second image component, the second image component being such that, if, from the pilot'"'"'s point of view, the first image component and the second image component are in a pre-specified configuration on the helmet mounted display, the aircraft is established on a predefined glide slope;
displaying, by the helmet mounted display, to the pilot, a third image component, the position of the third image component on the helmet mounted display being dependent upon the position on the helmet mounted display of the second image component;
displaying, by the helmet mounted display, to the pilot, a fourth image component, the fourth image component indicating a first position on the helmet mounted display, the first position being such that if, from the pilot'"'"'s point of view, the third image component is located at the first position, the first image component and the second image component would be in the pre-specified configuration on the helmet mounted display from the pilot'"'"'s point of view;
acquiring, by the one or more processors, a second value, the second value being a value for the velocity of the aircraft relative to the runway, the second value being different to the first value; and
displaying, by the helmet mounted display, to the pilot, a fifth image component, the fifth image component indicating a second position on the helmet mounted display, the second position being such that if, from the pilot'"'"'s point of view, the third image component is located at the second position, the second image component would be located at a position on the helmet mounted display that it would have if the first image component was calculated using the second value instead of the first value, and, from the pilot'"'"'s point of view, the first image component and the second image component were in the pre-specified configuration on the helmet mounted display.

Abstract
A method for displaying an image to a pilot (20) of an aircraft (2). The method comprises, using a first value of the velocity of the aircraft (2) relative to a runway (4), displaying, on a HMD (24), an indication of a first position for an image component (e.g. a FPM) (36), the first position being the position, from the pilot'"'"'s point of view, that the image component (36) would occupy if the aircraft (2) was established on a predefined glideslope (16); using a second value different to the first value, displaying, on the HMD (24), an indication of a second position for the image component (36), the second position being the position, from the pilot'"'"'s point of view, that the image component (36) would occupy if the aircraft (2) was established on a different glideslope.

acquiring, by one or more processors operatively linked to a helmet mounted display, a first value, the first value being a measurement of the velocity of the aircraft relative to a runway upon which the aircraft is to be landed; displaying, by the helmet mounted display, to the pilot of the aircraft, a first image component, the position of the first image component on the helmet mounted display being dependent upon the first value, said position of the first image component being a horizontal position relative to the helmet mounted display; displaying, by the helmet mounted display, to the pilot, a second image component, the second image component being such that, if, from the pilot'"'"'s point of view, the first image component and the second image component are in a pre-specified configuration on the helmet mounted display, the aircraft is established on a predefined glide slope; displaying, by the helmet mounted display, to the pilot, a third image component, the position of the third image component on the helmet mounted display being dependent upon the position on the helmet mounted display of the second image component; displaying, by the helmet mounted display, to the pilot, a fourth image component, the fourth image component indicating a first position on the helmet mounted display, the first position being such that if, from the pilot'"'"'s point of view, the third image component is located at the first position, the first image component and the second image component would be in the pre-specified configuration on the helmet mounted display from the pilot'"'"'s point of view; acquiring, by the one or more processors, a second value, the second value being a value for the velocity of the aircraft relative to the runway, the second value being different to the first value; and displaying, by the helmet mounted display, to the pilot, a fifth image component, the fifth image component indicating a second position on the helmet mounted display, the second position being such that if, from the pilot'"'"'s point of view, the third image component is located at the second position, the second image component would be located at a position on the helmet mounted display that it would have if the first image component was calculated using the second value instead of the first value, and, from the pilot'"'"'s point of view, the first image component and the second image component were in the pre-specified configuration on the helmet mounted display. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 14, 15)

12. Apparatus for displaying an image to a pilot of an aircraft, the apparatus comprising:
-
one or more processors configured to determine respective specifications for a first image component, a second image component, a third component, a fourth component, and a fifth component; and a helmet mounted display operatively coupled to the one or more processors and configured to display, to the pilot, the first image component, the second image component, the third component, the fourth component, and the fifth component in accordance with the determined specifications;
whereinthe position of the first image component on the helmet mounted display is dependent upon a first value for the velocity of the aircraft relative to a runway upon which the aircraft is to be landed, said position of the first image component being a horizontal position relative to the helmet mounted display; the second image component is such that, if, from the pilot'"'"'s point of view, the first image component and the second image component are in a pre-specified configuration on the helmet mounted display, the aircraft is established on a certain glide slope; the third image component is such that the position of the third image component on the helmet mounted display is dependent upon the position on the helmet mounted display of the second image component; the fourth image component indicates a first position on the helmet mounted display, the first position being such that if, from the pilot'"'"'s point of view, the third image component is located at the first position, the first image component and the second image component would be in the pre-specified configuration on the helmet mounted display from the pilot'"'"'s point of view; the fifth image component indicates a second position on the helmet mounted display, the second position being such that if, from the pilot'"'"'s point of view, the third image component is located at the second position, the second image component would be located at a position on the helmet mounted display that it would have if the first image component was calculated using a second value of the velocity of the aircraft relative to the runway instead of the first value, and, from the pilot'"'"'s point of view, the first image component and the second image component were in the pre-specified configuration on the helmet mounted display; and the second value is different to the first value. - View Dependent Claims (13)
