Combined altitude and height-above-ground indicator for an aircraft

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.
