Abstract

A display system and method is provided for deployment on board a vehicle and includes a data source that provides the display system with data indicative of at least time, position, and velocity of the vehicle. The system comprises a monitor, a display included within the monitor for displaying range data indicative of a specific distance and time data indicative of time it takes to travel the specific distance, an input device, and a processor coupled to the monitor and to the input device and configured to (1) render symbology on the display visually representative of the time data and the range data, and (2) update the range data, and correspondingly change the time data in response to the change in range data made via the input device.

Claims

1. A method for displaying range and time on a display in an aircraft display system and visually rendering on the display a textual representation of the distance between a first location to a second location and a predicted travel-time from the first location to the second location, the method comprising:

generating range symbology in the form of a range ring visually representative of the distance;

displaying the range symbology on the display;

generating symbology visually and textually representative of the predicted travel-time;

displaying the travel-time symbology on the display;

changing the displayed travel time via an input device;

generating updated range symbology corresponding to the change in travel-time;

displaying the updated range symbology;

changing the displayed range via the input device;

generating updated time symbology corresponding to the change in range; and

displaying the updated time symbology.

2. A method according to claim 1 wherein the first location is a predetermined location.

3. A method according to claim 2 wherein the first position corresponds to the location of the aircraft.

4. A method according to claim 3 further comprising:

generating symbology visually representative of a range window;

displaying the range window on the display; and

displaying the range symbology inside the range window.

5. A method according to claim 4 further comprising:

generating symbology visually representative of a time window;

displaying the time window on the display; and

displaying the time symbology inside the time window.

6. A method according to claim 5 wherein the range window is positioned on the range ring.

7. A method according to claim 5 wherein the time window is positioned on the range ring.

8. A method according to claim 5 wherein the time window and the range window are positioned on the range ring.

9. A method according to claim 2 wherein the first location is remote from the aircraft.

10. A method according to claim 9 the second location is a position on the aircraft'"'"'s intended travel path.

11. A display system for deployment on board an aircraft including a data source that provides the display system with data indicative of at least time, position, and velocity of the vehicle, comprising:

a monitor included within the display system;

a display coupled to the monitor for displaying range data indicative of a specific distance and time data indicative of time it takes to travel the specific distance;

an input device for changing the range and the distance; and

a processor coupled to the monitor and to the input device and configured to (1) render symbology on the display visually representative of the time data and the range data, and (2) update the range data;

(3) update the distance data;

(4) correspondingly change the time data in response to the change in range data made via the input device; and

(5) correspondingly change the range data in response to the change in the distance data.

12. A display system according to claim 11 wherein the processor is further configured to generate symbology visually representative of a range window containing range data and a time window containing time data.

13. A display system according to claim 11 wherein the input device comprises:

a cursor control device for selecting one of the range window and the time window; and

a rotary knob for varying data in the selected window.

14. A process to be carried out by an avionics display system including a cockpit display, a monitor, a processor, and input device coupled to the processor, deployed on a host aircraft, for visually rendering on the cockpit display the distance between a first location and a second location and the predicted flight-time from the first location to the second location, the process comprising:

generating range symbology in the processor visually representative of the distance between the first location and the second location;

displaying the range symbology on the vehicle display;

generating time symbology in the processor visually representative of the time to fly from the first location to the second location;

displaying the time symbology on the cockpit display;

changing the time symbology via the input device;

updating the range symbology responsive to changing the time symbology;

changing the range symbology via the input device; and

updating the time symbology in response to the change in range symbology.

15. A process according to claim 14 further comprising generating symbology in the processor visually representative of a range window graphic for enclosing the range symbology and a time window graphic for enclosing the time symbology.
