The system includes an image display device, a data storage device, a flight management system, a processing unit in operable electronic communication with the image display device, the data storage device, and the flight management system. The processing unit includes a computer processor that is configured to receive a time-based requirement to a point of interest associated with operation of the aircraft. Via the image display device, a flight display includes a graphically depicted time tape. The time tape includes a time scale. Also graphically depicted within the time tape is the point of interest using a first symbology and the time-based requirement using a second symbology. Operational parameter data of the aircraft allows determination of the ability of the aircraft to achieve the time-based requirement and graphical depiction within the time tape of the ability of the aircraft to achieve the time-based requirement using a third symbology. ## Claims ### Claim 1 A display system configured to provide a display to a flight crew of an aircraft comprising: an image display device; a data storage device; a flight management system; and a processing unit in operable electronic communication with the image display device, the data storage device, and the flight management system, wherein the processing unit comprises a computer processor that is configured to: receive a time-based requirement to a point of interest associated with operation of the aircraft; provide via the image display device a flight display including a graphically depicted time tape, wherein the time tape comprises a time scale; graphically depict within the time tape the point of interest using a first symbology; graphically depict within the time tape the time-based requirement using a second symbology, different than the first symbology; query the flight management system to obtain therefrom operational parameter data of the aircraft, determine an ability of the aircraft to achieve the time-based requirement based upon the operational parameter data; and in a first mode of operation to graphically depict within the time tape the ability of the aircraft to achieve the time-based requirement using a third symbology, different than the first symbology and second symbology; and in a second mode of operation to graphically depict within the time tape an indicator of progress of the aircraft to the time-based requirement using the third symbology, wherein the mode of operation is selected by the processing unit based upon the time-based requirement. ### Claim 2 (depends on 1) The display system of claim 1, wherein the first symbology is a first color and the second symbology is a second color that differs from the first color. ### Claim 3 (depends on 2) The display system of claim 2, wherein the first symbology is a first color and the third symbology is a third color that differs from the second color. ### Claim 4 (depends on 1) The display system of claim 1, wherein the first symbology is a first shape and the second symbology is a second shape that differs from the first shape. ### Claim 5 (depends on 4) The display system of claim 4, wherein the first symbology is a first shape and the third symbology is a third shape that differs from the second shape. ### Claim 6 (depends on 1) The display of claim 1, wherein one of the first symbology and the second symbology is an alpha-numeric symbol. ### Claim 7 (depends on 1) The display of claim 1, wherein one of the first symbology and the second symbology is an alpha-numeric symbol, and the third symbology is a shape. ### Claim 8 (depends on 1) The display system of claim 1, wherein one of the first symbology and the second symbology is an alpha-numeric symbol, and the third symbology is a color. ### Claim 9 (depends on 1) The display of claim 1, wherein the point of interest comprises a required time of arrival requirement (RTA), a waypoint requirement (WPT), a mission point requirement (MPT), an arrival point requirement (APT), a reporting point requirement (RPT), a fueling point in air (FPT) or a reporting altitude requirement (ALT). ### Claim 10 A method for providing a display to a flight crew of an aircraft comprising: receiving a time-based requirement to a point of interest associated with operation of the aircraft; providing a flight display including a graphically depicted time tape, wherein the time tape comprises a time scale; graphically depicting within the time tape the point of interest using a first symbology; graphically depicting within the time tape the time-based requirement using a second symbology, different than the first symbology; receiving operational parameter data of the aircraft; determining an ability of the aircraft to achieve the time-based requirement based upon the operational parameter data; and in a first mode of operation graphically depicting within the time tape the ability of the aircraft to achieve the time-based requirement using a third symbology, different than the first symbology and second symbology; and in a second mode of operation to graphically depict within the time an indicator of progress of the aircraft to the time-based requirement using the third symbology, wherein the mode of operation is selected by the processing unit based upon the time-based requirement. ### Claim 11 (depends on 10) The method of claim 10, wherein the first symbology is a first color and the second symbology is a second color that differs from the first color. ### Claim 12 (depends on 11) The method of claim 11, wherein the first symbology is a first color and the third symbology is a third color that differs from the second color. ### Claim 13 (depends on 10) The method of claim 10, wherein the first symbology is a first shape and the second symbology is a second shape that differs from the first shape. ### Claim 14 (depends on 13) The method of claim 13, wherein the first symbology is a first shape and the third symbology is a third shape that differs from the second shape. ### Claim 15 (depends on 10) The method of claim 10, wherein one of the first symbology and the second symbology is an alpha-numeric symbol. ### Claim 16 (depends on 10) The method of claim 10, wherein one of the first symbology and the second symbology is an alpha-numeric symbol, and the third symbology is a shape. ### Claim 17 (depends on 10) The method of claim 10, wherein one of the first symbology and the second symbology is an alpha-numeric symbol, and the third symbology is a color. ### Claim 18 (depends on 10) The method of claim 10, wherein the point of interest comprises a required time of arrival requirement (RTA), a waypoint requirement (WPT), a mission point requirement (MPT), an arrival point requirement (APT), a reporting point requirement (RPT), a fueling point in air (FPT) or a reporting altitude requirement (ALT).
