TCAS VSI display

1. An electronic display on an aircraft for presenting “fly-to” commands on a vertical speed indicator during a TCAS traffic or resolution advisory condition, wherein said display comprises:

a full range, semicircular depiction of a vertical speed indicator scale;

a vertical speed indicator marker;

a viewing window showing a digital readout of the current vertical speed of said aircraft; and

TCAS resolution advisory indicators along a periphery of said vertical speed indicator scale,

wherein said vertical speed indicator scale is comprised of graduations along an arc;

wherein said vertical speed indicator marker shows the current vertical speed of said aircraft on said vertical speed indicator scale; and

wherein the size of said display is enlarged relative to the size of a vertical speed indicator scale shown during non-TCAS traffic or resolution advisory conditions.

2. The electronic display of claim 1 , wherein said display overlies at least a portion of adjacent depictions of other flight information on a common viewing device.

3. The electronic display of claim 2 , wherein said common viewing device is a LCD screen.

4. The electronic display of claim 1 , wherein said adjacent depictions of other flight information is comprised of altitude.

5. The electronic display of claim 1 , wherein said adjacent depictions of other flight information is comprised of heading.

6. The electronic display of claim 1 , wherein said vertical speed scale has a continuous range with indices at 0 (zero) feet per minute, ±500 feet per minute, ±1000 feet per minute, ±1500 feet per minute, ±2000 feet per minute, ±2500 feet per minute, ±3000 feet per minute, ±4000 feet per minute, ±5000 feet per minute, and ±6000 feet per minute.

7. The electronic display of claim 1 , wherein said vertical speed indicator marker is comprised of a pointer.

8. The electronic display of claim 1 , wherein said vertical speed indicator marker is comprised of a numeric display.

9. The electronic display of claim 1 , wherein said vertical speed indicator marker is comprised of a pointer and a numeric display.

10. The electronic display of claim 1 ,

wherein said TCAS resolution advisory indicators are comprised of at least one red arc and at least one green arc;

wherein said red arc indicates a no-fly segment; and

wherein said green arc indicates a fly-to segment.

11. The electronic display of claim 10 , wherein said vertical speed indicator marker is shown in a red color when said current vertical speed of said aircraft is within said no-fly segment of said TCAS resolution advisory indicators.

12. The electronic display of claim 10 , wherein said vertical speed indicator marker is shown in a green color when said current vertical speed of said aircraft is within said fly-to segment of said TCAS resolution advisory indicators.

13. The electronic display of claim 10 , wherein at least a portion of said vertical speed indicator scale lying along said no-fly segment is shown in a red color.

14. The electronic display of claim 10 , wherein at least a portion of said vertical speed indicator scale lying along said fly-to segment is shown in a green color.

15. The electronic display of claim 10 , wherein said digital readout in said viewing window is shown in a red color when said current vertical speed of said aircraft is within said no-fly segment of said TCAS resolution advisory indicators.

16. The electronic display of claim 10 , wherein said digital readout in said viewing window is shown in a green color when said current vertical speed of said aircraft is within said fly-to segment of said TCAS resolution advisory indicators.
