First Claim
Patent Images
1. A combined altitude and height-above-ground indicator for an aircraft, comprising:
- a first sensor and a second sensor which respectively sense altitude and height-above-ground information;
means for processing the altitude and height-above-ground information supplied by said first and second sensors, respectively; and
means for displaying said altitude and height-above-ground information, showing said altitude and height-above-ground information against each other to a same linear and vertical scale, comprising a first part represented by a first graduated strip showing the altitude and a second part represented by a second graduated strip, adjacent to the first graduated strip, showing the height-above-ground, wherein said first part scrolls past a first stationary pointer, and movement of said first part is automatically controlled by the altitude information produced by the first sensor and processed by the means for processing, wherein said second part scrolls past a second stationary pointer, and movement of said second part is automatically controlled by the height-above-ground information produced by the second sensor and processed by the means for processing, and wherein said first and second stationary pointers are stationary at the same level.
